Everything that this guy said is absolutely what is happening to our car exactly I mean it’s very dangerous and I can’t believe the number of people who have this issue and I can’t believe Mercedes has not had a recall on this I mean it’s a crime and it’s a shame
I'm a 2012 c250 owner and have experienced this same problem since 2014. This is a horrible issue for anyone that has experienced this problem. I'm hoping there hasn't been any fatalities do to this problem. I'm also upset that Mercedes consistently denies how serious this problem is. I understand that there's wear and tear on vehicles but there's people who have this problem driving out the dealership. I'm reaching out to all of you to help support on starting a recall on this problem. Below is a link on where to file a complaint. I hope you all share 5 minutes of your time to submit your complaint. Flexx keep up the good work bud. NHTSA link: www.safercar.gov/
I have had the same problem twice now whilst on the interstate trying to overtake. I agree this is a serious safety issue and I have completed a report (only took 5 minutes) at the link you provided, thanks. I think everyone should file a complaint to force the issue and make Mercedes Benz take responsibility before (if it’s not too late already) a fatal accident occurs. I have a 2014 C250 with 67k miles on the clock.
I took 10 minutes to file a detailed report for same issue 2012 C250 with P0002 code power loss while accelerating, I hope something is done about this, Thanks for all the great info.
I thought I was the only one with this problem this happens so much to me when I push down pretty heavy on the gas and after a couple times of turning the car off it will go away but still is a problem because I can never actually press down hard GREAT VIDEO FLEXX
Truly appreciate Flexx Alexander for posting this video. FYI to all, this high pressure fuel pump is indeed part of extended factory vehicle warranty/recall by MB USA. They finally recognized this to be a major issue. I have a 2013 MB C250, so check with MB USA. My car had this issue for years, initially thought to be the turbo, but after turbo was repaired the acceleration issue continued for years and no one could really figure out the problem. Recently tried to sell my car and the buyer test driving it floored the gas and the issue came back and I panicked but scanned my car, got the P0002 code and came across this video. Took my car to dealership and got it repaired for free, saved me thousands. My car finally drives perfect as it should.
Yes, I already shared that a few months back. I got the letter as well. Only thing that sucks is that most people already got it repaired (not by MB) so they can’t get reimbursed or their car is way out of the extended warranty period. I feel like MB knew about it but didn’t want to do anything until the last second so it’s less exposure to them covering the fix. This is the same exact route they took with the camshaft adjuster issue on the c250.
Thanks a million! Happened to my W204 too. The dealer could not find the root cause. Since I had watched your video, I insisted on double-checking and they finally confirmed it's the High Pressure Fuel Pump!
One thing everyone should know is the way this turbo setup up is built you can't just punch the gas , I've noticed if you treat it like it has a big turbo setup and want to pass someone, if u hold the downshift lever to the left and the car will shift to the safest gear and then just gradually give it gas all the way down as your buildin boost until youve passed traffic or merged etc. Never step on the gas all at once and the kickdown function on this model is just terrible so I personally don't use it , hope this helps
Yo Alex, as you probably knew already, YEP, I had this problem last year where the dealership had my car for over 3 months on hold because the high pressure fuel pump was on back order and there was only 5, THAT's 5 HFP's in the entire USA available for distribution. but this is a known issue with Mercedes Benz. I'd say though that the real problem is that MB hasn't made enough inventory of these HFP's to send out to the US for replacements. Also, for all those who may not know, these same 2012-2015 C250's also have a passenger air back recall on them as well. AND AGAIN, this issue can not be resolved because the original company that made the airbags went out of business. So MB had established another company who was suppose to take this up, but again, the airbags are on back order.
I had that issue with mine. I was told where I got my 2013 c250 w204 that I had a bad coil?? It got replaced and hasn’t happened to me again….yet. But good to know this info. Thanks flex.
I’m having this issue right now. I found a kool little solution besides shutting the car off. I just put the car into sport mode and only hit the gas about a quarter ways to the floor. The car gets moving and doesn’t put it into limp mode. Now it’s not a fix at all but you’ll definitely get more power to pass on the freeway and you’ll be able to continue to drive until you have enough to get the problem fixed. I’m about to buy another HPFP soon and try to replace it myself.
Leave it in eco and just hold the lever in the downshift position and it will put it in the safest gear , then treat it like you have a big turbo setup and gradually step on the gas till it's all the way down and shift accordingly (reason for eco is because in sport it will shift closer to redline , and will require more work and fuel from the pump)
@@BC2FITTY even when I do that, eco mode still doesn’t have the power I’m looking for or need to pass, sometimes. So what I’ve learned is to just hit the paddle and upshift the car on my own before it gets close to redline. I have the power to pass and don’t have to worry about the pump putting in too much work.
Flexx!! My man with the best videos and content💪🏼 this has happened to me at least 3 times and now it makes sense the high pressure fuel pump I’ve known how to fix it, by shutting the car on and off a few times to reset it. Thank you for seriously posting this! You are awesome brother! 🤙🏼
I have this issue in my 2013 C200. I called Mercedes Benz Australia head office and informed them in order to recall all those model cars .they said we haven't receive any complaint except you. So all those who have this kind of issue contact Mercedes Benz Australia and let them know. They will for sure recall and will be fixed for free. Thanks
So I have had the issue for 2 years. I have found 2 ways to minimize the issue: 1. Always put the car is (S) Sport mode and not (E) Eco. 2. Add Octane booster to your tank at each fill-up, I get the $3.49 Oreilly octane booster. Keep in mind I am in California, and most stations are limited to octane 91. My confusion is if it is the HPFP pump, why have I been able to drive it for 2 years without complete failure. I get the issue about twice a week P0002, limp mode, turn it off and restart. Is there not some way to rebuild it yourself?
Stan Nelson I'm having the same issue now going on one year but it is now happening more frequently. Shut off the car and restart the car resets everything. No one can find a code or what's what wrong. My car is always in sport now so I won't buck but since last night it's doing it on all accelerating. I'm actually scared now so I'm here reading and googling.
I made a comment of this b4. Pretty much my rule of thumb is not to floor it when ur gas is low, and when I mean low. I'm talking about little below a quarter. I had this happen b4 and it's not a fun time trying to fix it in a middle of a commute. In my case, all I had to do is clear the code and it was back to normal.
I have a '13 C250 Coupe. I love it! What contrast from my '72 280Se 4.5 or my 89 560SEL. The C Class handles like a go-cart. Just twice now, when I nail it the bogs, check engine goes on and looses power as what seems like its turbo is not responding, but does not go to limp mode. I runs at whatever speed you want to go, shifts fine but just as if it does not have the extra boost. If I shut off and re-start. it still runs like described above. If I clear codes it will run fine, and will provide high power as long as I load it slower, not nailing it instantaneously. The effect is akin to an old 4 barrel without secondary accelerator pump. A big bog that is, but eventually gets up and goes. This just started, so no trouble shooting yet, and the only thing I loose it the ability to nail it. ANy suggestions or insight would be appreciated.
I ran into this issue and as soon as I turned my car off and waited about 5min, before starting it again, and it was 100% normal, however if you try to start it right after you turn it off it is likely that the car will not start the first time and the check engine light will be on!!! Car needs to have 5-10 min before it is started again, I have noticed that other people have been doing this as a temporary solution just to get where you need to go!
Same thing happened to me. How do we go about getting Mercedes to do a recall it's such a common issue surely there's a way to bring it to their attention. Any suggestions?
Hey Flex man thanks for the info. Just got off phone with my service rep and he confirmed the warranty extension on the high pressure fuel pump does qualify my car so taking it in this Thursday.
Amazing how many people have this problem .. so with me it happens when I pass .. and when I pass and push down on the Accelerator quickly and forcefully it then goes limp .. and suddenly I can’t even go over 30 miles an hour .. it’s incredibly dangerous and a really serious issue
There was finally an extended warranty on it (I think). You’d have to reach out to Mercedes Benz USA and give them your vin and ask. Still a little late by Mercedes’ if you ask me.
@@TheFlexxGarage there was and I took mine in and they said the fuel pump wasn’t the issue and it came back with a broken charge pipe that they wanted $1k to fix
I appreciate this b/c i just started having this issue. The dealership said its like a 12oo-15oo job. Any one know how to or have instructions on how to fix it once you get the part. I'm pretty decent in repairing things my self and would enjoy not having to pay for the labor Thanks guys !!
My 2014, C250 has same issue with no 0002 code but check coolant level light was on. After an hour I drove, it ran fine. Lately coolant has been disappearing but there isn't any visible sign of leaks or not seen in engine oil either. Any suggestions? Thank you.
If you have a “low coolant” light and you checked your overflow coolant reservoir and it’s full, then you’re just experiencing the common known issue of the floating sensor inside the reservoir that’s stuck on the bottom making the car think it’s low on coolant. Coolant does evaporate over time but if coolant is truly disappearing (a lot), then you have a leak externally that should show up under the car on the floor or (worst case) you might have a leak where the coolant is mixing with the oil. If you check under your oil cap and it looks milky, you may have a head gasket leak allowing coolant to mix with oil. That’s not good cause oil could be going into the cylinders and cause the spark plugs to underperform and sometimes not even detonate. All speculations. You should def seek a qualified mechanic before things get worst or dangerous.
2 days ago I picked up a slightly used like new 2014 C250 with the same identical problem. Thank you for this information. I just saw further below the MB Warranty extension for 10 years. You are the BEST!!! Thank you for making a very informative video on this subject!!!
@@hyperbull8450 , I just now saw your response. Sorry for the delay. The best thing to do is have your VIN number checked at the Mercedes-Benz dealership for any type of warranty extension. The 10-year 100K warranty extension on my car is a factory warranty extension for a known flaw on the high pressure fuel pump.
I have this problem with my Mercedes the first time I pushed the gas pedal all the way in I did get the same thing u say I did it like 3 times and I did get the check engine light so I don’t push my pedal gas all the way anymore ☹️ but good to know how to fix this problem thanks a lot bro you have a lot of information very interesting things about Mercedes thanks bro
My 2014 C250 did the same thing in January 2023. I saw this video and thought, that has to be it. (I've been a professional VW/Audi Technician since 1985 with Mercedes experience). I was passing a car on freeway and "boom" the car went into Limp mode with the check engine light turning on immediately. I erased the fault and all was fine for 6 months until it happened again when merging almost full throttle on the freeway in June 2023. I saw here in the past comments that there was a warranty extension still available on my car with only 64K miles. I visited the MB dealer in Bellevue Washington and told them about the high psi fuel pump warranty extension for 10 years or 100K miles. They charged me $250 to check and said that there was a low-voltage fault software update that has to be done first. I said OK, do the update. My car went into LIMP mode again 3 days later when punching the gas pedal quickly to beat the light from turning red. I was at 35MPH and hit the gas. It went into LIMP mode again with the check engine light turning on immediately. I brought it back to the dealer in July 2023 in Bellevue Washington and said,,, " I'll will bet you $100 that the repair is 100% for sure the high psi fuel pump" The dealer ordered the FUEL pump, installed the high psi fuel pump in August 2023. I'm HAPPY to report that the car is 100% fixed. I drove the car hard on the freeway, and top speed with ZERO issues. I've made sure it fixed before typing this info. I'm happy. Thank you for the useful information.
Wow…wish they didn’t give you a runaround the first time. That type of stuff pisses me off when shops just throw parts and services at the problem and make you pay instead of truly diagnosing the issue and fixing it right the first time. I’m glad the issue was resolved. This is not the first time with Mercedes, they also had the camshaft adjuster issue on the c250 that they didn’t issue a warranty extension until like 8 years afterwards. They just sent me a warranty extension for a purge valve on my 2016 w205 c300….after I already paid a third party shop over $1,000 to replace because I was out of warranty. Let’s see if Mercedes will even reimburse me for their defect.
@@TheFlexxGarage ,, 🙋🏻♂️. I know, and I paid $250 for a software update that I knew was NOT going to fix it but I paid it anyway. I really like the service advisor at the dealer. He called me and told me they accidentally broke a vacuum line while replacing the high pressure fuel pump. They ordered the vacuum line which put my car down for a total of 10 days for a 2 day repair. The advisor was really really good at taking care of me with car rental and loaner cars. But, 3 days after the repair, the check engine light came on with an EVAP system small leak detected fault. I'm diagnosing on my own, I saved the screenshots. (Before I smoke the lines I will replace the gas cap and maybe the evap purge valve). Thanks again for everything and your cool UA-cam channel 🙋🏻♂️🙋🏻♂️🤙🤙
I dont get a check engine light but if I gun it from a stop the car jerks as if I'm pressing the gas and letting up repeatedly. I wonder if its the same fuel pump issue
Is this the same in a diesel??? I was told it’s the boost gauge or turbo but the mechanic said he couldn’t see any cracks or issues with the turbo piping it’s very well maintained. He then said it could be the suction of the turbo….. my car is intermittent it goes like the clappers but then decides to space out and do what is noted in this video so it could be a fuel pump….. 💁🏼♂️ even told it could be catalytic converter but chucked Catclean down and that cleared up
I have the exact same problem. I’ve been taking it to the dealership and they “can’t seem to figure it out,” which is possibly BS. Took it in again today with the code P000277. Here’s the notes from the mechanic: “the quantity control valve has a malfunction, the commanded position can not be reached. Followed guided tests and fuel pressure testing all passed. Passed test resistance in high pressure pump. Passed test resistance from ME through engine harness.” The dealership even told me they called Mercedes because they had never seen the issue. My car does not do it every time I hit the gas. It’s done it many times over the past few months. This week it did it on Monday and Wednesday. I get that maybe it’s a glitch right now, not a complete fail which is why the dealership “can’t diagnose the problem”, but I don’t really want to wait until it completely fails. I kinda feel like they just fed me a load of bullshit. I literally found very similar issues with a single Google search. Grrrrr! Sorry, I’m a little pissed right now.
I just thought a conductor plate and my CL500 2003 I am not getting no accelerate when I step in the gas the car feel like it's going to limp mode that's why I do not take the highway no more trying to correct this problem my work on my car myself my check engine light was clear first after I did the conductor plate but it popped back on not sure if it's the throttle position sensor
I have a mercedes C200 with w204 engine 1800cc turbo year 2012 amg when I start the engine no acceleration when I press the gas pedal what could be the issue
Hi, I have a 2010 c250 same problem it only happen once but it was pretty scary I didn't know at the time but if I would pot the shift on neutral shot the car off and turn it back on quickly it would be O.K. , I went to the Mercedes dealer the guy never mentioned the fuel pump he said something else that it could cost me if rebuild $700 I can't remember what, now I don't know if there is any difference between 2010 and 2012 C250 models as I sad it only done once but if you know any thing for the 2010 C250 please let me know. Thanks Roman
Yes sir, I had 2009model c200 kompresor, troble code p2263 ,supercharger boost system performance, what is coz of problems sir,what should I do,hope you will share me your idea,tnx
I had the same code and it kept going into limp mode. Took it to Mercedes...and it was the pump. Luckily it was still under the cpo warranty. It was on back order for 3 months but no $ out of pocket
I bought an used 2013 C250 from a private party and had what you described happen to me driving on fwy. Car is at local MBZ mechanic for going on 1 day and check engine light isn't coming on and he cannot see what issue is. So waiting game. He said I may have to take it to MBZ dealership if he cannot figure out what is going on with my car.
hello, thanks for vid. Had the same replaced the pump, was fine for 3 months and now again the same happens. I replaced it with a new OEM original pump. Any idea what else might be the real culprit here? I don't believe I was so unlucky that the new one got broken so fast. Any ideas??
@@TheFlexxGarage Is there any fuel filter on this engine? I found air and oil filter parts but no fuel filter to be replaced. Maybe it has a different name?
I have this problem with my 2013 Mercedes I was looking for why my Mercedes is doing this and I got a notification for Mercedes today that I need to take my Mercedes to the dealer to fix this problem for free just amazing they going to replace the high pressure fuel pump they don’t say why but I think is because this problem u talking about great 👍
After clearing the same error code, the malfunction light did not come on again, but the sound in the car's engine changed. Do you think it would be harmful for me to continue like this? Some people told me that there is a possibility of mixing gasoline with oil.
Have had a similar issue only when doing hard pulls either at a stand still or slow rolling around 10 mph in manual mode and it’d cut power and engine brake immediately around 5-7k rpm’s so I’d immediately put it back into normal drive mode and just drive normally and it’d be fine. Didn’t really think much about it for a while as I daily drive it and stopped doing so many pulls or just being hard on the car because I don’t want anything else to break but here recently I just started having starting issues where the engine will continuously turn over for at least 3 seconds before finally a very rough start. Runs fine after that even when idling. Tested battery and was good replaced alternator after testing it and still didn’t fix so made a post online and one guy said it could possibly be the fuel pump pressure regulator as it sounds like it’s having to build up pressure from the videos I posted of me starting it up. Definitely could use some advice if there’s a chance that could be potentially the issue or at-least part of as I had other people saying I might need a whole new spark/coil pack kit, coolant possibly leaking into a cylinder from a bad head gasket, etc. so I don’t feel like spending more time and money on parts I don’t need. I could and probably should just take it to a shop but don’t feel like spending the money and would rather do it myself if feasible.
Also forgot to mention my cars a 2012 c63 amg base model which has the M156 engine so I figured it’d all be pretty similar parts and configuration given the year model you have.
Had the same issue with power loss on my MB c250 2012 and P0002 error or P008A (low pressure fuel system - pressure too low), sometimes both at the same time. First thing you need to do is to replace fuel filters (there is regular fuel filter under the left back seat and coarse filter before the low pressure pump under the right back seat, you'll have to disassemle fuel pump a little bit to find that kind of pouch filter). After replacing first filter and cleaning second I can accelerate up to 6200rpm without any errors. Hope this help to somebody
I experienced this same issue. i am ordering a new fuel pump and also checking the filter sock you mentioned. on the xentry it shows low fuel pressure.
Nope. Cause I had the issue at 30k miles on my 2012 C250 and I had a different issue at 40k miles on my 2016 C300. Good ole Mercedes! Definitely check to see if there’s a recall or extended warranty coverage. Cause if it’s a common problem, Mercedes usually has an extended warranty for it.
I have a 2014 C250 with 42000mi. I was sent a letter from mercedes on this issue. I have the same issue, the service manager said that only if it sets a certain code will they warranty it. He didnt tell me what the code was. He said they have to use the mercedes scanner. i reset my engine light and had a p0002 fuel pressure circuit code. The light went out but the code said it was permanent on my scanner.
Hi can you help me my C250 coupe 2012 is on limp mode and It's been involved in a accident I fixed the car body and air bags put the car is on limp mode and not fixing using your method any help
I have the same problem with my 2010 c350. When I press the pedal down all the way it goes limp. But it rarely happens. Once every 10-15 times I floor it. I’m not sure if it is the same reason because mine has a different engine
I have the issue of car shaking on acceleration and can’t go up to speed, it happens every time but there is no CEL and no codes on the scanner! It is really frustrating and I am not sure what to do. I have c250 2014 coupe.
I had the same issue I changed out the ignition coil but the trick is you have to find out which one is failing I did it buying just one and swapping it out with each coil one by one I did it the cheap way to find out which failing just to make sure it was the ignition coil instead of buying all of them and it not being the problem but once I found out it was the ignition coils I did replace all of them and no more shaking on acceleration or weird vibrations
I have a c300 2008 and i m having this problem but the mechanical plugged my car to a scanner and he told me that everything is fine...idk does the w203 c300 2008 have that problem too?
That’s not a permanent fix. Everyone has done that temporarily but you should def get it checked out before you get stranded. There was an extended warranty on the fuel pump. You should have your local Benz dealership run your vin number to see if you’re qualify for a free replacement.
I have a 2012 c300 with a front left malfunction service required and the airbag light is on what’s the problem with this just start a few months back please help
Hi Flexx. 2012 C250 with 128k miles just got the turbo replaced. I just experienced the limp mode you mentioned. It wasn't pretty. p0002 error code. Do you have a video on replacing the HPFP?
I just recently replaced my HPFP. If you haven’t done the job yet, just reply to this message and I’ll help you out. It’s a pretty annoying job but I’ve managed to learn a few short cuts to expedite the process. Always willing to share to help others out.
Hi flexx. my car is 2009 mercedez benz c class. My problem is that my car won't accelerate, it's not engaging in gears, it's like it's In limp mode. The check engine light came on and it's me 3281 fault code saying the boost pressure control flap is malfunctioning. Kindly help me out
This just happened to me a few days ago for the first time. I was literally leaving my local Mercedes dealership after getting an oil change. I was trying to pass a car and pressed hard on the gas. Loss acceleration. I made a U turn and went straight back to the dealership. They told me what the code read but also said the check engine light turned off by itself. “If it happens again, bring it back in.” 😑
Did you find out I'm having the same problem on hard acceleration. Changing into next lane merging into the freeway. Limp mode check engine light blinks then stays on. Then when I restart the car it dissapeared no codes.
Hi. So I had the light just come on and I bought my own battery tester to check it. I’m getting this code to. Does that mean it needs to go into the shop? Or can I clear it and just watch the speed? I’m lost in what to do.
I currently have a vehicle I purchased at Auction... looks like they replaced the HPFP but I'm not sure .. I say that because the hose clamps are aftermarket, unless all they did was change hoses. I cant get car to run unless I use a starter fluid. Any idea how to check fuel pressure? Cant seem to find a Schrader valve.
hello every one I do have this problem today, it is safe drive the car for a few days? or I do have to stop the car, of course jut to wait some. money to fix it
I just fixed the high pressure fuel pump but got code 0705 now for the transmission and i think the transmission code caused the fuel pump code! So i think i fixed the pump for nothing! Make sure to check all codes before spending 1500 on the fuel pump. Now i gotta fix the transmission electrical circuit fml
I bought a MB c250 at an auction and I seem to have the same concern about stalling and lossing it's power when accelerating plus engine light turns on. Auction return policy is good for only 7 days. Where can I get a used high pressure fuel pump and how much will labor cost to install it. Is there any recall for this part by MB dealer. When I change it how can I better take care of it to make it last or how many times will this happen to me for it's(car)lifetime.
it never happened to me but happened to alot of people. I suggest you read through the comments and see where people bought their pumps and if there's any news on MB covering it.
I have a 2013 C250 same problem I'm super tired of cars with the same problem and no one does anything about it I had a Nissan with the same problem with a catalytic converter soooo many complaints
I have a 2018 c300 4matic w205. Two days ago I got a service B, yesterday when I turned on the engine, once I started driving, I couldn’t accelerate, the power was low. Do you think is the same issue of your video?
Don’t know. Could be anything. If you experienced that issue, then your car should of thrown a check engine light. Only way to know the true issue is to hook up a OBD2 scan tool/reader to the car and see what fault made the check engine light come on.
I have a Benz c250 2013 For some reason when I drive it doesn’t let me pass 3rd gear It simply goes back down There was a p0002 code that popped up and then went away What would you recommend I do?
My mercedes a200 w176 no power sometimes when press full accelerating no check engine light blinking and fault code NO1 P059700 the coolant thermostat has an electrical fault or open circuit No2 P233827 the knock limit of cylinder 3 was execeed(the signal change rate is above the permissible limit value) No3 P029921 the boost pressure of turbocharger 1 is too low(the signal amplitude is less than the minimum amplitude...anyone has ever had something like this?
Hey so question guys, Im a DIY type of guy and dont want to pay crazy $$$ to the dealership. Anyone have instructions on how to fix this? Any steps or guides ???
I recently bought a 2009 Mercedes c300 and the gas gage stopped working. Do you think it's the fuel level sensor or the Fuel pressor sensor? The runs amazing and has lots of power but the gage doesn't work and some times it shows a full tank. Anyone else have this problem?
Hi guys, I'm owner of a SLK 250 2014 with only 10.000 km, and I'm having this issue occasionally. I've already replaced the HPFP pump wondering it could fix, but it happened again last week while I was travelling. Does anyone have another clue to fix this issue?
Many causes for the code alone, the acceleration setting it may be the pump indicator, just tuning on without acceleration could be one of the other problems. Someone gave general problems associated with this code (Disconnected plug to the fuel regulator, Possible corrosion in the sensor connector, Damage to the sensor wiring to the ECM, Leaking or defective fuel pressure regulator, Damaged fuel pump, The ECM is damaged), this was general info, I don't know if Mercedes even has a separate regulator or if that is part of the pump.
Hard to tell cause any could fail. Could be a defective brand new one or a fully serviced refurbished one. It’s gonna come down to your risk level. In my opinion, I would wanna do this once and be done so I would get one directly from a dealership.
Same thing happening with my 2014 c250 coupe my car battery has died 4 times in less than 3 weeks and every time I try to start the car makes a noise which it goes away after a couple seconds …
check your codes; i had this happen with a misfire from an ignition coil. Could also be spark plugs - change out all four coils if you want to get it over with because all four of mine misfired in a month, but not after.
I have s63 amg w222 year 2015. I cannot get rid off of this misfiring. I changed sparkplugs, i changed ignition coil pack. Same . Now its going into limp mode only when i press hard the acceleration. What could be ? Anyone had something similar?
What’s the fault code when your car is plugged to a code reader? Your car doesn’t have to have a check engine light on, for there to be a fault. The check engine light only comes on if the same fault occurs more than once within a certain time frame. If you have the issue once and car shuts down, fault is there but not enough for a check engine light to pop up.
Most don’t have the check engine light when it happens. But if you plug in a code reader, a fault maybe stored. Cause check engine light won’t come unless a fault happens multiple times within a certain time frame. Again, doesn’t mean there no issue. Just means the issue happened but not enough to trigger the light.

Everything that this guy said is absolutely what is happening to our car exactly I mean it’s very dangerous and I can’t believe the number of people who have this issue and I can’t believe Mercedes has not had a recall on this I mean it’s a crime and it’s a shame
I'm a 2012 c250 owner and have experienced this same problem since 2014. This is a horrible issue for anyone that has experienced this problem. I'm hoping there hasn't been any fatalities do to this problem. I'm also upset that Mercedes consistently denies how serious this problem is. I understand that there's wear and tear on vehicles but there's people who have this problem driving out the dealership. I'm reaching out to all of you to help support on starting a recall on this problem. Below is a link on where to file a complaint. I hope you all share 5 minutes of your time to submit your complaint.
Flexx keep up the good work bud.
NHTSA link: www.safercar.gov/
I have had the same problem twice now whilst on the interstate trying to overtake. I agree this is a serious safety issue and I have completed a report (only took 5 minutes) at the link you provided, thanks. I think everyone should file a complaint to force the issue and make Mercedes Benz take responsibility before (if it’s not too late already) a fatal accident occurs. I have a 2014 C250 with 67k miles on the clock.
I took 10 minutes to file a detailed report for same issue 2012 C250 with P0002 code power loss while accelerating, I hope something is done about this, Thanks for all the great info.
I thought I was the only one with this problem this happens so much to me when I push down pretty heavy on the gas and after a couple times of turning the car off it will go away but still is a problem because I can never actually press down hard GREAT VIDEO FLEXX
Me too. It sturtles
Truly appreciate Flexx Alexander for posting this video. FYI to all, this high pressure fuel pump is indeed part of extended factory vehicle warranty/recall by MB USA. They finally recognized this to be a major issue. I have a 2013 MB C250, so check with MB USA. My car had this issue for years, initially thought to be the turbo, but after turbo was repaired the acceleration issue continued for years and no one could really figure out the problem. Recently tried to sell my car and the buyer test driving it floored the gas and the issue came back and I panicked but scanned my car, got the P0002 code and came across this video. Took my car to dealership and got it repaired for free, saved me thousands. My car finally drives perfect as it should.
Yes, I already shared that a few months back. I got the letter as well. Only thing that sucks is that most people already got it repaired (not by MB) so they can’t get reimbursed or their car is way out of the extended warranty period. I feel like MB knew about it but didn’t want to do anything until the last second so it’s less exposure to them covering the fix. This is the same exact route they took with the camshaft adjuster issue on the c250.
@@huantsai9406 does w205 have that recall or what is it called
Thanks a million! Happened to my W204 too. The dealer could not find the root cause. Since I had watched your video, I insisted on double-checking and they finally confirmed it's the High Pressure Fuel Pump!
Nice!
so they replaced only the high pressure fuel pump and the problem was solved?
And how much did it cost?
One thing everyone should know is the way this turbo setup up is built you can't just punch the gas , I've noticed if you treat it like it has a big turbo setup and want to pass someone, if u hold the downshift lever to the left and the car will shift to the safest gear and then just gradually give it gas all the way down as your buildin boost until youve passed traffic or merged etc. Never step on the gas all at once and the kickdown function on this model is just terrible so I personally don't use it , hope this helps
Yo Alex, as you probably knew already, YEP, I had this problem last year where the dealership had my car for over 3 months on hold because the high pressure fuel pump was on back order and there was only 5, THAT's 5 HFP's in the entire USA available for distribution.
but this is a known issue with Mercedes Benz. I'd say though that the real problem is that MB hasn't made enough inventory of these HFP's to send out to the US for replacements.
Also, for all those who may not know, these same 2012-2015 C250's also have a passenger air back recall on them as well. AND AGAIN, this issue can not be resolved because the original company that made the airbags went out of business. So MB had established another company who was suppose to take this up, but again, the airbags are on back order.
Thank you so much for this. I had the same problem on 1.8 petrol w204 face-lift. Replaced the High pressure fuel pump and it works perfectly now.
I had that issue with mine. I was told where I got my 2013 c250 w204 that I had a bad coil?? It got replaced and hasn’t happened to me again….yet. But good to know this info. Thanks flex.
Flex, you are the MAN!! This is twice you've helped me with my car.
I’m having this issue right now. I found a kool little solution besides shutting the car off. I just put the car into sport mode and only hit the gas about a quarter ways to the floor. The car gets moving and doesn’t put it into limp mode. Now it’s not a fix at all but you’ll definitely get more power to pass on the freeway and you’ll be able to continue to drive until you have enough to get the problem fixed. I’m about to buy another HPFP soon and try to replace it myself.
Leave it in eco and just hold the lever in the downshift position and it will put it in the safest gear , then treat it like you have a big turbo setup and gradually step on the gas till it's all the way down and shift accordingly (reason for eco is because in sport it will shift closer to redline , and will require more work and fuel from the pump)
@@BC2FITTY even when I do that, eco mode still doesn’t have the power I’m looking for or need to pass, sometimes. So what I’ve learned is to just hit the paddle and upshift the car on my own before it gets close to redline. I have the power to pass and don’t have to worry about the pump putting in too much work.
Flexx!! My man with the best videos and content💪🏼 this has happened to me at least 3 times and now it makes sense the high pressure fuel pump I’ve known how to fix it, by shutting the car on and off a few times to reset it. Thank you for seriously posting this! You are awesome brother! 🤙🏼
I have this issue in my 2013 C200. I called Mercedes Benz Australia head office and informed them in order to recall all those model cars .they said we haven't receive any complaint except you. So all those who have this kind of issue contact Mercedes Benz Australia and let them know. They will for sure recall and will be fixed for free. Thanks
Described the problem with my 2014 C250 perfectly. Thanks for the video explanation.
So I have had the issue for 2 years. I have found 2 ways to minimize the issue: 1. Always put the car is (S) Sport mode and not (E) Eco. 2. Add Octane booster to your tank at each fill-up, I get the $3.49 Oreilly octane booster. Keep in mind I am in California, and most stations are limited to octane 91.
My confusion is if it is the HPFP pump, why have I been able to drive it for 2 years without complete failure. I get the issue about twice a week P0002, limp mode, turn it off and restart. Is there not some way to rebuild it yourself?
Stan Nelson I'm having the same issue now going on one year but it is now happening more frequently. Shut off the car and restart the car resets everything. No one can find a code or what's what wrong. My car is always in sport now so I won't buck but since last night it's doing it on all accelerating. I'm actually scared now so I'm here reading and googling.
I made a comment of this b4. Pretty much my rule of thumb is not to floor it when ur gas is low, and when I mean low. I'm talking about little below a quarter. I had this happen b4 and it's not a fun time trying to fix it in a middle of a commute. In my case, all I had to do is clear the code and it was back to normal.
I have a '13 C250 Coupe. I love it! What contrast from my '72 280Se 4.5 or my 89 560SEL. The C Class handles like a go-cart. Just twice now, when I nail it the bogs, check engine goes on and looses power as what seems like its turbo is not responding, but does not go to limp mode. I runs at whatever speed you want to go, shifts fine but just as if it does not have the extra boost.
If I shut off and re-start. it still runs like described above. If I clear codes it will run fine, and will provide high power as long as I load it slower, not nailing it instantaneously. The effect is akin to an old 4 barrel without secondary accelerator pump. A big bog that is, but eventually gets up and goes.
This just started, so no trouble shooting yet, and the only thing I loose it the ability to nail it. ANy suggestions or insight would be appreciated.
I ran into this issue and as soon as I turned my car off and waited about 5min, before starting it again, and it was 100% normal, however if you try to start it right after you turn it off it is likely that the car will not start the first time and the check engine light will be on!!! Car needs to have 5-10 min before it is started again, I have noticed that other people have been doing this as a temporary solution just to get where you need to go!
this guy just saved me from fixing sm other shit i thought was the problem thank you brotha !
Same thing happened to me. How do we go about getting Mercedes to do a recall it's such a common issue surely there's a way to bring it to their attention. Any suggestions?
I got that code twice already. Last year and just recently....customer support for Mercedes to make a complaint for a recall 1-800-367-6372
Wow I’ve been looking for this answer forever thank you sir
Hey Flex man thanks for the info. Just got off phone with my service rep and he confirmed the warranty extension on the high pressure fuel pump does qualify my car so taking it in this Thursday.
Nice
If you have a salvaged car do you think it still works
Amazing how many people have this problem .. so with me it happens when I pass .. and when I pass and push down on the Accelerator quickly and forcefully it then goes limp .. and suddenly I can’t even go over 30 miles an hour .. it’s incredibly dangerous and a really serious issue
There was finally an extended warranty on it (I think). You’d have to reach out to Mercedes Benz USA and give them your vin and ask. Still a little late by Mercedes’ if you ask me.
@@TheFlexxGarage there was and I took mine in and they said the fuel pump wasn’t the issue and it came back with a broken charge pipe that they wanted $1k to fix
I had the same issue mine was under aftermarket warranty. They changed my spark plugs coils and inner cooler. and that fixed it.
Did you have to pay anything?
@@GamingLife114 did you had to change all coils an would hesitate when you would step hard on the gas
I had the same issue on my 2013 C250, Mercedes replaced the high pressure fuel pump for free under the warranty extension!
There you go. Nice!
Was is forsure the problem and how was the difference with the new one
I appreciate this b/c i just started having this issue. The dealership said its like a 12oo-15oo job. Any one know how to or have instructions on how to fix it once you get the part. I'm pretty decent in repairing things my self and would enjoy not having to pay for the labor
Thanks guys !!
My 2014, C250 has same issue with no 0002 code but check coolant level light was on. After an hour I drove, it ran fine. Lately coolant has been disappearing but there isn't any visible sign of leaks or not seen in engine oil either. Any suggestions? Thank you.
If you have a “low coolant” light and you checked your overflow coolant reservoir and it’s full, then you’re just experiencing the common known issue of the floating sensor inside the reservoir that’s stuck on the bottom making the car think it’s low on coolant.
Coolant does evaporate over time but if coolant is truly disappearing (a lot), then you have a leak externally that should show up under the car on the floor or (worst case) you might have a leak where the coolant is mixing with the oil. If you check under your oil cap and it looks milky, you may have a head gasket leak allowing coolant to mix with oil. That’s not good cause oil could be going into the cylinders and cause the spark plugs to underperform and sometimes not even detonate.
All speculations. You should def seek a qualified mechanic before things get worst or dangerous.

2 days ago I picked up a slightly used like new 2014 C250 with the same identical problem. Thank you for this information. I just saw further below the MB Warranty extension for 10 years. You are the BEST!!! Thank you for making a very informative video on this subject!!!
when did this extended warranty start? or do i have to purchase that? im having the same problem at this moment!
i have a 2012 would my 10 year pass already?
The vehicle must be less then 120k miles
@@hyperbull8450 , I just now saw your response. Sorry for the delay. The best thing to do is have your VIN number checked at the Mercedes-Benz dealership for any type of warranty extension. The 10-year 100K warranty extension on my car is a factory warranty extension for a known flaw on the high pressure fuel pump.
I have this problem with my Mercedes the first time I pushed the gas pedal all the way in I did get the same thing u say I did it like 3 times and I did get the check engine light so I don’t push my pedal gas all the way anymore ☹️ but good to know how to fix this problem thanks a lot bro you have a lot of information very interesting things about Mercedes thanks bro
My 2014 C250 did the same thing in January 2023. I saw this video and thought, that has to be it. (I've been a professional VW/Audi Technician since 1985 with Mercedes experience). I was passing a car on freeway and "boom" the car went into Limp mode with the check engine light turning on immediately.
I erased the fault and all was fine for 6 months until it happened again when merging almost full throttle on the freeway in June 2023. I saw here in the past comments that there was a warranty extension still available on my car with only 64K miles.
I visited the MB dealer in Bellevue Washington and told them about the high psi fuel pump warranty extension for 10 years or 100K miles. They charged me $250 to check and said that there was a low-voltage fault software update that has to be done first. I said OK, do the update.
My car went into LIMP mode again 3 days later when punching the gas pedal quickly to beat the light from turning red. I was at 35MPH and hit the gas. It went into LIMP mode again with the check engine light turning on immediately.
I brought it back to the dealer in July 2023 in Bellevue Washington and said,,, " I'll will bet you $100 that the repair is 100% for sure the high psi fuel pump" The dealer ordered the FUEL pump, installed the high psi fuel pump in August 2023.
I'm HAPPY to report that the car is 100% fixed. I drove the car hard on the freeway, and top speed with ZERO issues. I've made sure it fixed before typing this info. I'm happy.
Thank you for the useful information.
Wow…wish they didn’t give you a runaround the first time. That type of stuff pisses me off when shops just throw parts and services at the problem and make you pay instead of truly diagnosing the issue and fixing it right the first time. I’m glad the issue was resolved. This is not the first time with Mercedes, they also had the camshaft adjuster issue on the c250 that they didn’t issue a warranty extension until like 8 years afterwards.
They just sent me a warranty extension for a purge valve on my 2016 w205 c300….after I already paid a third party shop over $1,000 to replace because I was out of warranty. Let’s see if Mercedes will even reimburse me for their defect.
@@TheFlexxGarage ,, 🙋🏻♂️. I know, and I paid $250 for a software update that I knew was NOT going to fix it but I paid it anyway.
I really like the service advisor at the dealer. He called me and told me they accidentally broke a vacuum line while replacing the high pressure fuel pump. They ordered the vacuum line which put my car down for a total of 10 days for a 2 day repair. The advisor was really really good at taking care of me with car rental and loaner cars.
But, 3 days after the repair, the check engine light came on with an EVAP system small leak detected fault.
I'm diagnosing on my own, I saved the screenshots.
(Before I smoke the lines I will replace the gas cap and maybe the evap purge valve).
Thanks again for everything and your cool UA-cam channel 🙋🏻♂️🙋🏻♂️🤙🤙
How much was it to get the new part installed
@@talkncough888 ,, under the warranty extension it does not cost anything to have the high pressure fuel pump replaced. $0
But how to know if my our car are under this warranty?@@MotoTouringWorldWide
I dont get a check engine light but if I gun it from a stop the car jerks as if I'm pressing the gas and letting up repeatedly. I wonder if its the same fuel pump issue
John Ray yes that's exactly what's happening to my c250 and I'm here trying to figure out what to do without getting ripped off by the dealership
Cumbias Con Sabor did you ever get it fixed?
any of you got the problem fix ??
Is this the same in a diesel??? I was told it’s the boost gauge or turbo but the mechanic said he couldn’t see any cracks or issues with the turbo piping it’s very well maintained. He then said it could be the suction of the turbo….. my car is intermittent it goes like the clappers but then decides to space out and do what is noted in this video so it could be a fuel pump….. 💁🏼♂️ even told it could be catalytic converter but chucked Catclean down and that cleared up
Hey flex , are there any DIY’s on how to replace the high pressure pump? I only see the secondary pump replacement located in the rear
I had a similar problem as well and I replaced it as well. But it's very expensive. Afterwards my problem was solved.
David Mofolo How long does it take to replace the unit?
What was the Cost David....
I have had my C250 for over 6 years. It has gone into limp mode in the first 2 years of owning it (only happen twice). It hasn’t happen ever again
what did you do to it to not have it happen again?
I have the exact same problem. I’ve been taking it to the dealership and they “can’t seem to figure it out,” which is possibly BS. Took it in again today with the code P000277. Here’s the notes from the mechanic: “the quantity control valve has a malfunction, the commanded position can not be reached. Followed guided tests and fuel pressure testing all passed. Passed test resistance in high pressure pump. Passed test resistance from ME through engine harness.” The dealership even told me they called Mercedes because they had never seen the issue. My car does not do it every time I hit the gas. It’s done it many times over the past few months. This week it did it on Monday and Wednesday. I get that maybe it’s a glitch right now, not a complete fail which is why the dealership “can’t diagnose the problem”, but I don’t really want to wait until it completely fails. I kinda feel like they just fed me a load of bullshit. I literally found very similar issues with a single Google search. Grrrrr! Sorry, I’m a little pissed right now.
Msbral Shotner did you fix your problem?
I just thought a conductor plate and my CL500 2003 I am not getting no accelerate when I step in the gas the car feel like it's going to limp mode that's why I do not take the highway no more trying to correct this problem my work on my car myself my check engine light was clear first after I did the conductor plate but it popped back on not sure if it's the throttle position sensor
I have a mercedes C200 with w204 engine 1800cc turbo year 2012 amg when I start the engine no acceleration when I press the gas pedal what could be the issue

Hi, I have a 2010 c250 same problem it only happen once but it was pretty scary I didn't know at the time but if I would pot the shift on neutral shot the car off and turn it back on quickly it would be O.K. , I went to the Mercedes dealer the guy never mentioned the fuel pump he said something else that it could cost me if rebuild $700 I can't remember what, now I don't know if there is any difference between 2010 and 2012 C250 models as I sad it only done once but if you know any thing for the 2010 C250 please let me know. Thanks

Yes sir, I had 2009model c200 kompresor, troble code p2263 ,supercharger boost system performance, what is coz of problems sir,what should I do,hope you will share me your idea,tnx
I had the same code and it kept going into limp mode. Took it to Mercedes...and it was the pump. Luckily it was still under the cpo warranty. It was on back order for 3 months but no $ out of pocket
What warranty did you have?
Had these symptoms in an SLK with same engine. Replaced hp pump, ended up being fuel pressure sensor .
Yeah. It could be the fuel pump for some cars as well.
I bought an used 2013 C250 from a private party and had what you described happen to me driving on fwy. Car is at local MBZ mechanic for going on 1 day and check engine light isn't coming on and he cannot see what issue is. So waiting game. He said I may have to take it to MBZ dealership if he cannot figure out what is going on with my car.
hello, thanks for vid. Had the same replaced the pump, was fine for 3 months and now again the same happens. I replaced it with a new OEM original pump. Any idea what else might be the real culprit here? I don't believe I was so unlucky that the new one got broken so fast. Any ideas??
Don’t know. Check your fuel filter too.
@@TheFlexxGarage Is there any fuel filter on this engine? I found air and oil filter parts but no fuel filter to be replaced. Maybe it has a different name?
I have this problem with my 2013 Mercedes I was looking for why my Mercedes is doing this and I got a notification for Mercedes today that I need to take my Mercedes to the dealer to fix this problem for free just amazing they going to replace the high pressure fuel pump they don’t say why but I think is because this problem u talking about great 👍
Yup. A few days ago I posted on my UA-cam community feed the warranty extension. Mercedes finally owned up to the issue I presented in the video.

Going to pick up my Benz today I bought a high pressure fuel pump and got them to replace it pray for me it worked haha
Update ?
Update ?
After clearing the same error code, the malfunction light did not come on again, but the sound in the car's engine changed. Do you think it would be harmful for me to continue like this? Some people told me that there is a possibility of mixing gasoline with oil.
Have had a similar issue only when doing hard pulls either at a stand still or slow rolling around 10 mph in manual mode and it’d cut power and engine brake immediately around 5-7k rpm’s so I’d immediately put it back into normal drive mode and just drive normally and it’d be fine. Didn’t really think much about it for a while as I daily drive it and stopped doing so many pulls or just being hard on the car because I don’t want anything else to break but here recently I just started having starting issues where the engine will continuously turn over for at least 3 seconds before finally a very rough start. Runs fine after that even when idling. Tested battery and was good replaced alternator after testing it and still didn’t fix so made a post online and one guy said it could possibly be the fuel pump pressure regulator as it sounds like it’s having to build up pressure from the videos I posted of me starting it up. Definitely could use some advice if there’s a chance that could be potentially the issue or at-least part of as I had other people saying I might need a whole new spark/coil pack kit, coolant possibly leaking into a cylinder from a bad head gasket, etc. so I don’t feel like spending more time and money on parts I don’t need. I could and probably should just take it to a shop but don’t feel like spending the money and would rather do it myself if feasible.
Also forgot to mention my cars a 2012 c63 amg base model which has the M156 engine so I figured it’d all be pretty similar parts and configuration given the year model you have.
Had the same issue with power loss on my MB c250 2012 and P0002 error or P008A (low pressure fuel system - pressure too low), sometimes both at the same time. First thing you need to do is to replace fuel filters (there is regular fuel filter under the left back seat and coarse filter before the low pressure pump under the right back seat, you'll have to disassemle fuel pump a little bit to find that kind of pouch filter). After replacing first filter and cleaning second I can accelerate up to 6200rpm without any errors. Hope this help to somebody
Thank you for sharing your experiences!!!!
I experienced this same issue. i am ordering a new fuel pump and also checking the filter sock you mentioned. on the xentry it shows low fuel pressure.
My 2021 c300 is having this problem, gonna take it to the shop tomorrow.
Good luck!
@ isn’t it crazy I’m getting these problems at 45k miles
Nope. Cause I had the issue at 30k miles on my 2012 C250 and I had a different issue at 40k miles on my 2016 C300. Good ole Mercedes!
Definitely check to see if there’s a recall or extended warranty coverage. Cause if it’s a common problem, Mercedes usually has an extended warranty for it.
I have a 2014 C250 with 42000mi. I was sent a letter from mercedes on this issue. I have the same issue, the service manager said that only if it sets a certain code will they warranty it. He didnt tell me what the code was. He said they have to use the mercedes scanner. i reset my engine light and had a p0002 fuel pressure circuit code. The light went out but the code said it was permanent on my scanner.
Hi can you help me my C250 coupe 2012 is on limp mode and It's been involved in a accident I fixed the car body and air bags put the car is on limp mode and not fixing using your method any help
I have the same problem with my 2010 c350. When I press the pedal down all the way it goes limp. But it rarely happens. Once every 10-15 times I floor it. I’m not sure if it is the same reason because mine has a different engine
It’s not so much about the engine but the fuel pump/fuel filter that’s the culprit.
I have the issue of car shaking on acceleration and can’t go up to speed, it happens every time but there is no CEL and no codes on the scanner! It is really frustrating and I am not sure what to do. I have c250 2014 coupe.
Probably can be as easy as a fuel filter change. If not, take it somewhere to get the fuel pump checked out.
I had the same issue I changed out the ignition coil but the trick is you have to find out which one is failing I did it buying just one and swapping it out with each coil one by one I did it the cheap way to find out which failing just to make sure it was the ignition coil instead of buying all of them and it not being the problem but once I found out it was the ignition coils I did replace all of them and no more shaking on acceleration or weird vibrations
I have a c300 2008 and i m having this problem but the mechanical plugged my car to a scanner and he told me that everything is fine...idk does the w203 c300 2008 have that problem too?
Thanks for the video! I had similar instance the other day. All seems OK with tuning engine off and giving it a rest for a while.
That’s not a permanent fix. Everyone has done that temporarily but you should def get it checked out before you get stranded. There was an extended warranty on the fuel pump. You should have your local Benz dealership run your vin number to see if you’re qualify for a free replacement.
I have same problem with my w212 CGI 2010. But i have a question is this possible for fixing or cleaning ?

This just happened to me a few days ago for the first time. I was literally leaving my local Mercedes dealership after getting an oil change. I was trying to pass a car and pressed hard on the gas. Loss acceleration. I made a U turn and went straight back to the dealership. They told me what the code read but also said the check engine light turned off by itself. “If it happens again, bring it back in.” 😑
Indeed very disappointing response from the dealership!!
Did you find out I'm having the same problem on hard acceleration. Changing into next lane merging into the freeway. Limp mode check engine light blinks then stays on. Then when I restart the car it dissapeared no codes.
Had that issue on my C250, it was the fuel pump. Had the factory warranty so it was a free fix
Hi. So I had the light just come on and I bought my own battery tester to check it. I’m getting this code to. Does that mean it needs to go into the shop? Or can I clear it and just watch the speed? I’m lost in what to do.
I currently have a vehicle I purchased at Auction... looks like they replaced the HPFP but I'm not sure .. I say that because the hose clamps are aftermarket, unless all they did was change hoses. I cant get car to run unless I use a starter fluid. Any idea how to check fuel pressure? Cant seem to find a Schrader valve.
There is no Schrader valve. I use a laptop with Autoenginuity enhanced for Mercedes.

I just fixed the high pressure fuel pump but got code 0705 now for the transmission and i think the transmission code caused the fuel pump code! So i think i fixed the pump for nothing! Make sure to check all codes before spending 1500 on the fuel pump. Now i gotta fix the transmission electrical circuit fml
I bought a MB c250 at an auction and I seem to have the same concern about stalling and lossing it's power when accelerating plus engine light turns on. Auction return policy is good for only 7 days. Where can I get a used high pressure fuel pump and how much will labor cost to install it. Is there any recall for this part by MB dealer. When I change it how can I better take care of it to make it last or how many times will this happen to me for it's(car)lifetime.
it never happened to me but happened to alot of people. I suggest you read through the comments and see where people bought their pumps and if there's any news on MB covering it.
I have a 2013 C250 same problem I'm super tired of cars with the same problem and no one does anything about it I had a Nissan with the same problem with a catalytic converter soooo many complaints
Thanks, it just happened to me on my way home. Pulled out to pass and halfway around she stumbled.
I have a 2018 c300 4matic w205. Two days ago I got a service B, yesterday when I turned on the engine, once I started driving, I couldn’t accelerate, the power was low. Do you think is the same issue of your video?
Don’t know. Could be anything. If you experienced that issue, then your car should of thrown a check engine light. Only way to know the true issue is to hook up a OBD2 scan tool/reader to the car and see what fault made the check engine light come on.
I have a Benz c250 2013
For some reason when I drive it doesn’t let me pass 3rd gear
It simply goes back down
There was a p0002 code that popped up and then went away
What would you recommend I do?
Don’t know. Better off to take it to a mechanic and get it diagnosed.
My mercedes a200 w176 no power sometimes when press full accelerating no check engine light blinking and fault code NO1 P059700 the coolant thermostat has an electrical fault or open circuit No2 P233827 the knock limit of cylinder 3 was execeed(the signal change rate is above the permissible limit value) No3 P029921 the boost pressure of turbocharger 1 is too low(the signal amplitude is less than the minimum amplitude...anyone has ever had something like this?
Hey so question guys, Im a DIY type of guy and dont want to pay crazy $$$ to the dealership. Anyone have instructions on how to fix this? Any steps or guides ???
Its only two bolts.. there is a video on YT
If the code p0002 cane up and my car jerks a little do you think it would be from the fuel pump?
I recently bought a 2009 Mercedes c300 and the gas gage stopped working. Do you think it's the fuel level sensor or the Fuel pressor sensor? The runs amazing and has lots of power but the gage doesn't work and some times it shows a full tank. Anyone else have this problem?
Replacing mine now at Mercedes of Lafayette. Entire job is $1,700! This is my second one! Part is $725.00 the rest is labor. 3.5 to 4 hour job!
Ouch...
They dropped the price of this pump to around $440 now.
This happen to me but on 2013 C300 4matic, only happen once so far.
Same here! Pretty frustrating having to restart the car a few times to get it out of limp mode ..
I had this come up around 60k miles on my 2014. Covered under warranty. At 117k mikes now and it’s back. 😢
Oh no! That’s sucks. Wonder if they replaced it with another crap one that’s why it only last like 60k both times.
Hi guys, I'm owner of a SLK 250 2014 with only 10.000 km, and I'm having this issue occasionally. I've already replaced the HPFP pump wondering it could fix, but it happened again last week while I was travelling.
Does anyone have another clue to fix this issue?
Are you getting the check Engine light while its doing it ?
Many causes for the code alone, the acceleration setting it may be the pump indicator, just tuning on without acceleration could be one of the other problems. Someone gave general problems associated with this code (Disconnected plug to the fuel regulator, Possible corrosion in the sensor connector,
Damage to the sensor wiring to the ECM,
Leaking or defective fuel pressure regulator, Damaged fuel pump,
The ECM is damaged), this was general info, I don't know if Mercedes even has a separate regulator or if that is part of the pump.
I have w204 c180 2013 i have some problem what I have to do?
Did you find the solution?
where can you buy a used high pressure fuel pump for a Mercedes SLK250. What sites are the best to go to? I am having this problem with my SLK250
eBay. There’s tons of refurbished ones for under $300
@@TheFlexxGaragedo they fail after a while too? I mean refurbished ones? Thnx for feedback
Hard to tell cause any could fail. Could be a defective brand new one or a fully serviced refurbished one. It’s gonna come down to your risk level. In my opinion, I would wanna do this once and be done so I would get one directly from a dealership.
I have the same issue on my 2012 W204 and its doing exactly what you just mensioned
Common issue
Is this HPFP responsible for P0001?
And what about for p0004 my c63 w205
Same thing happening with my 2014 c250 coupe my car battery has died 4 times in less than 3 weeks and every time I try to start the car makes a noise which it goes away after a couple seconds …
That’s not the same thing. You have a different issue and it’s probably this. ua-cam.com/video/rwtAdVvZqdk/v-deo.html
hey Flexx! is there any way to message you for some help? or should i just comment my issue. really looking for your help you know all!
Will this also cause the car to shake as well when idling?
check your codes; i had this happen with a misfire from an ignition coil. Could also be spark plugs - change out all four coils if you want to get it over with because all four of mine misfired in a month, but not after.
if you have a diesel check dpf as it could be blocked
Same thing happened to me but the code was p0008 ?
Hi.. I recently experienced with my ML250, it went to limp mode.. I was panicking. What is wrong?
Its 2014.. I know if i take it to dealership it will cost me thousands of $$$ 😫😫
Hey Flexx I have a c250 2011. Same problem??
I have s63 amg w222 year 2015. I cannot get rid off of this misfiring. I changed sparkplugs, i changed ignition coil pack. Same . Now its going into limp mode only when i press hard the acceleration. What could be ? Anyone had something similar?
What’s the fault code when your car is plugged to a code reader? Your car doesn’t have to have a check engine light on, for there to be a fault.
The check engine light only comes on if the same fault occurs more than once within a certain time frame. If you have the issue once and car shuts down, fault is there but not enough for a check engine light to pop up.
I have the same problem on my w205 but I don’t have check engine light tho
Most don’t have the check engine light when it happens. But if you plug in a code reader, a fault maybe stored.
Cause check engine light won’t come unless a fault happens multiple times within a certain time frame. Again, doesn’t mean there no issue. Just means the issue happened but not enough to trigger the light.
@ do you think is the pedal sensor or throttle sensor
@@TheFlexxGarage do you think by cleaning the sensor
