Swirl Flap Motor BYPASS on JEEP / MERCEDES Engine OM642 (FIX Limp Mode)
Вставка
- Опубліковано 3 лис 2020
- Hi, this 'how to' video shows an in depth installation of an emulator (resistor mod) on a OM642 engine (3.0 CRD) commonly found on various vehicles (Jeep/Mercedes/Dodge/Chrysler) commonly manufactured between 2005-2010. The vehicle in the video is a 2008 Jeep Grand Cherokee.
This will allow your vehicle to come out of limp mode by tricking it into thinking the swirl flap motor is still functioning. Once fitted the car will not perform as well (not as good low speed engine performance/fuel economy/emissions) but in 'real world' driving you will be unlikely to notice any difference.
Here is the UK eBay Affiliate link for the Bypass Emulator ebay.to/2GriAAk
Remember this is a workaround to get your vehicle going again. Obviously it would be better to replace the failed swirl flap motor, but access to it can be time consuming. If you are getting the garage to do the work it may not be cost effective, OR maybe you need to save up the money, and this resistor trick will get you motoring again until the funds allow the proper fix.
Many thanks, Vince :-) - Навчання та стиль
Exceptionally well done. Remember: do not over tighten the air intake clamps at the turbo. That plastic can break easily especially when old. Costly to replace.
Always it's nice watching you repair car. Also I love that you said every screw sizes - I hate when automotive videos don't mention that.
You're the best UA-camr ever, absolutely professional output, like a high school professor, so clear, so easy...Thank you very much indeed
Great, GREAT description. very helpful. better explanation than all you can hear or see on youtube.
Well DONE!
4 or 5 years now I done this fix and its still working fine ,I don't even think about it now.
I don't even have a Jeep, but I watched to help support you. I like the way that you take the job through showing every step, showing every bolt head size, etc. You explain everything..."this goes here, that goes there, watch out for this, etc." That is the way these videos SHOULD be done. Too often the content provider glosses over things and assumes that the audience understands what was skipped over. Keep it up!
Great video Vince, nice, clear and easy to follow.
Great educational video Vince simple and well laid out for both professionals and novice.Thanks again and keep your style for other videos please!
I really like your automotive videos, please keep them coming
That's a great tech tip not only for jeep owners but other vehicles
just done this to my 2008 ml280 , works great , its been in limp mode for agers , thanks for the great video bud
man of many talents , well in vin
Thanks for good detailed explanation of every single step. Thats the way I like video tutorials.
Thanx Vince, for the informative Bypass Emulator fitting, on the OM642 engine !!
Where do u get them from
Excellent. Couldn’t get the emulator local in remote Western Australia but I did fit a 4.7k ohm resister to the plug. Fixed the problem and now gets more boost (power). Saved me over $2000.
Did you put the in the hol 3 and 4?
It looks like there are variations to this resistor like different watts etc. which one did you use?
@@Thecreekysailboat I doubt it matters, the controller input uses very little power, you just want the computer to see that something consumes a bit of electricity when it sends the signal to move the flaps, that's it.
Thanks a lot for this film, excelent job. I had the same problem in Chrysler 300C 3.0 CRD and I put the 4.7 kOhm resistor into the plug with hot glue and tape and it works total cost about 0,5EUR.
Likewise. Perfect fix.
I have the same car where did you buy the resistor?
We had a similar issue with a ford galaxy it was the EGR VALVE but we blocked it off with a blanking plate
It had the same issue with lack of power
Great video vince
Perfect video, 10/10, unlike the majority of presenters.
Hose clamps Vince! What in the world jubilee clip? Never heard of such a critter. Awesome that you've made a vid of working on a vehicle
Jubilee brand are the original hose clamp manufacturer.
@@ianhaylock7409 learned something new thanks bud
Super video, incredibly clear. Very helpful
Nice work Vince I might look you up if my 2.2 diesel Civic needs doing. I used to have that same engine in the old Mercedes C320 cdi that I used to own a few years ago.
Great info about the impact of a non working part
Doing mine today . Cheers for the video
ML w163 om612 same issue, removed swirl flaps and put in the resistor, works perfectly!
Fitted the resistor to my Jeep WK yesterday, incredible work around, would recommend it.
Where do you get this resistor
Any difference in performance?
Great video Vince! Thank you! I will be trying this on my 2008 Jeep Diesel 3.0 CRD. Do you suggest I order the gaskets as well before I open it up or do you think they won't be needed?
Stay safe and keep it coming 😊
I enjoyed the video like always 👍
Thanks for this video, I had exactly the same problem, paid £14.99 for the resistor plug and £14.99 for the new turbo pipe seals.
Hi Gary, are you in the UK? Guessing so by £ symbols! Please could you provide a link to where you got these parts? My car is doing this and so is my dad's, both Merc E320 2008 and 2007!! Thanks
Vince, please advise where to purchase resistor plug. Thank you.
My new favorite expression: the nobbly bits.
It's a typical English informal expression lol
The rails that move all the flaps on both intake banks were broken on my vehicle, replaced the entire intake with brand new parts (vehicle still had the original factory PCV valve, never changed, so that was probably the source of all the carbon....). I just ordered this resistor dongle from ebay and put it on, should be good to go with zero issues from now on. Thanks mate!
Carbon comes from the EGR . Combines with oil from the PCV to create gunk .
Great work around they must sell a few of those devices to bother putting a 4k7 in a plug in the first place let's hope it passes the MOT for you like you said let's hope it runs for many years to come for your brother.
Our merc currently this problem and gone into limp mode. We have ordered this peice of tackle in hope it solves the problem cheaply. Thank you for such a clear explanation of how to do it all. Great job Vince!
Hi mate where can u buy this resistor plug from cheers
@@jezkhan5448 amazon
Cheers for the reply much appreciated does it Matter if their a cheap China copy?
@@jezkhan5448 no....not at all, it basically fools the car computer telling it the swirl flaps are in a closed position. You need to get the correct rating resistance for your car though. Forums will help with that. Good luck its sorted ours perfectly
@@PClem59 aw mate your star honestly didn’t expect a reply as your comment was from over 10 months ago! And what are those? I thought it was just the resistor plug and go? Am I missing something here lol 😂
Hello Vince,
Just did the swirl flap motor bypass in my OM642 G-Wagen 320CDi and as i expected the limp mode is gone. My engine is a little different because in my car it has a "T" intake and 02 MAF sensors. I feel the engine a little louder and it seems that sound like it "breaths" different. Do you find any long term problems with this mod?
I used a 4.7K Ohms resistor and i think its a little bit bigger so its probably 1watt and not 0.5 watts as the ones you showed in your video.
Thank you for the great video.
Great work 👍
Fantastic work-around Vince! maybe a start into motor vehicle maintenance for some future vids? Or a long term side project like converting an old fossil fuel car into an EV?
You can do the same thing with older Toyota secondary air injection systems that fail - you can install a resistor in the temperature sensor circuit so that the truck always thinks it is over a certain temperature so that it just never runs the secondary air system. Typically people will remove the air pumps and valves as well and block the holes off with a plate, but it is a neat little trick to fool the ECU into never activating the system and therefore never throwing a code. (Secondary air is a total joke anyways as all it does is blow air into the exhaust system when the air temps are cold enough on start to "reduce" emissions by diluting them - lol. That is basically all it does.)
You guys call it a swirl flap!!!?!?? That’s hilarious and accurate, I love it!
What do you call it then? :)
@@cidercecil well on the Gm cars I’m used to working on they like to call them intake tuning valves..... I’m going to start calling them swirl flaps from here on out!
That is a recognised description. Used in service bulletins.
Where can that emulator/resistor plug be ordered from as I like it. Thanks and keep informing us Vince.
이곳은 서울입니다. 제차량은 ml350d bluetek 입니다. 림프 모드여서 저항 4.7k 구매하여 영상처럼 설치 하여 해결했던거에 대해 진심으로 감사합니다. 다만한가지 팁은 엔진경고등 을 지우는 오토미션 초기화(다른 유튜브 참고)해주니 경고등이 사라지고 정상으로 돌아 왔어요 할렐루야! 다시한번 본 영상에대해 감사를 드립니다.
Good practical tutorial
good luck mate
great fix
You just saved yourself $3k at the shop here in the States ✌
Good fix!
Worked perfectly... thanks for the vid, saved me £1500 that I was quoted lol
Still working without issue? Have you had an MOT over the past 10 months - How did it get on?
Thanks a ton bro
I have a w211 e280cdi
Will try the mod with resistor
Lets see how it works out
Thanks in advance
Hi Vince it looks like I’m going to have to do this to my old Mercedes can you tell me did your brother have any issues afterwards? Thanks George
A handy workaround, but will it get through the emissions test like that?
Damn swirl flaps are a major design flaw. They are problematic on BMWs too. Good workaround though. 👍
Hi
A great video you made there 👍
I am having the same fault now ( grand cherokee 3,0 CRD , 2006)
My question is, what difference does the installing of the resister do ?
I mean is it healthy for the engine ?
Regards
Leif, Denmark
The swirl valves stop working and stay open . Doesn't have any negative impact on the engine .
Well done👍😁
V8 is the way to go man
My swirl flap motor packed up , this has been done for over a year now and seems to go better and slightly quicker off the mark .
Do you know if there’s an electrical diagram that depicts how this resister functions in the cpu circuit?
Always remember to line up your knobbly bits!
The oil that caused that problem in the first place comes from the crankcase vent valve and should be treated as a consumable,
bad diaphragm or weak spring allows turbo to suck oil vapor or in extreme cases oil, some goes through the turbo and some leaks past the seal onto flap motor.
Hi there I've got resistor. but I was just wondering were can I connect my resistor which wire colour
Super.
Thank You
Did this today on our Merc. with the resistor - problem seems fixed and no more limp mode.
I have a 2007 Jeep larodo Australian model - I would like to know if turning on and off the key 3 times shows the codes on the dash board?.
I have the same problem as you and will try your method to correct this issue.
Hello, i have exactly the same car and problem. First I tought tht the problem was the throttle. What is exactly the brand and model of the emulator you plugged in?
And how can the car still run without the Flap motor? Thanks
Loving the auto electronics fix. Hopefully you’ll do another for a Mitsubishi Colt CZT. 👍
Hola disculpa dónde se compra la resistencia tendrás el link del producto
When you do this modification still can you pass the emissions inspection?? (TÜV in germany ) ??
I had the same issue with a 2018 Jeep Liberty!
Dear Mr Vince
I have had this for two years but i could not get rid of engine amber light. Is there anything you could suggest? Thanks in advance.
Danke!
Thank you 👍👍
I used a old abs sensor it was giving 5 ohms reading and plug it into the middle to pins it done the job and reset the engine light
I have a chrysler 300c with the same engine can you please send me the link where you bought the resistor .. I want yo purchase my self to because I have the same problem
What is the name of that part to bypass and where do I get it
Nice easy fix to get out of limp mode =D I am wondering what the Swirl Flap does now lol
That just sounds way too sexual for No Nut November...
"Oooooh, naughty naughty" 😜
Are the swirl flaps stuck closed now? Doesn't that create issues?
Plus it's saves you money
Hi 'Vince'. Great Vid. Maybe make a Transmission fluid and coolant change ones?
Why did you put his name in quotation marks...?
@@RWL2012 Just a goof on my part that's all.
I have the same car same problem pls what is that resistor called need more info about it and where to get it from
Awesome!
Can you show how to replace the throttle body location please or show me where it's located please? Thanks
Can you tell what type bypass emulator you used ? The link you shared is removed. The dealer did a oil cooler seal job and they messed up my car.
COULD ANYONE TELL ME WHERE THE MANIFOLD ABSOLUTE PRESSURE SENSOR (MAP) IS ON THESE CARS. I HAVE A 3.0l 2005 TURBO DIESEL JGC. PICTURES PLEASE. THANK YOU.
Hi there i want one of these but i live in Houston Texas, how can i get one shipped to USA ? Any help would be appreciated, thanks
Well I guess the turbo is going to be the next thing that lets go, if its leaking all that oil.
No, the oil comes from the „Kurbelwellenentlüftung“ crankcase breathing.
@@jasperlongman7668 and the torn oring inside intercooler hose. mine was so.
I kinda missed a description of this swirl flap motor in your video, how it affects engine operation if it's not working, and how the resistor would make the engine computer believe nothing is wrong... So...........
The flap closes part of the flow in the intake when idle. This creates some turbulence which creates a better mix between the diesel fuel and the air, which results in a cleaner burn. On higher RPMs, there's more air flow and that will have enough turbulence by itself and the flap can be open, to make sure enough air can be drawn into the engine.
If that flap is stuck open, it causes slightly more emissions when idling. The car owner won't mind that. Problem is at the government: cars need to meet emission standards, no matter what. So car manufacturers probably decided to impose 'limp mode' on a swirl flap motor failure. Limp mode usually drives the car owner to fix the problem. Just a dash light: not so much.
If the flap is stuck closed, I think, limp mode would be justified: car will not be able to get enough air: incomplete fuel burn, more turbo wear, more soot, more particulate filter regeneration cycles, which may not succeed when there's not enough air.
I think, this flap has a spring that keeps it open and it closes when the motor gets actuated. But I'm not sure.
The resistor is weird.
4700 Ohms is not accurate for representing a motor coil. That would allow for just 2.5 mA. That's 0.03 Watt of power. That will not move a flap, for sure. But then again... if it's enough for the ECU, it's okay. If the resistor would be more in the range of what the motor would use, it would heat up too much.
4700 Ohms would be okay for a sensing circuit. But a fixed resistance would then indicate that there's nothing moving.
So... weird value.
I think this is a nice cheap fix that will keep this car usable until the next big thing goes. This car's turbo seems to be a bit of a concern.
(edited: fixed some grammatical and spelling)
I think the position of the flap is measured by a potentiometer, nothing to do with the motor it just measures the change in resistance with the change of the position of the flap. It's possible the motor still works.
@@coyote5735 If that would be so, then, replacing the potentiometer with a resistor would make the ECU believe that the flap is always in the same position. That would surely generate an error.
@@fluffyblue4006 Obviously not that's why this fix works. ECU enables the valve to open and looks for an open confirmation, the designers didn't think to make it self testing, not an overly important system. I suspect the valve only makes a minimal difference to emissions.
Looks like a service is also needed.
I did not come right with that method maybe it is because of my resistor
Which is 4.67k
Do you have any tips
2nd from india. mymate vince is the only reason i watch his videos.
Well I’d hope you watch the mymatevince channel for Vince, it’s his channel lol
Hello Vince
good afternoon
Can You Help me in this situation please.
I have a jeep grandCherokee 2009 crd 3.0 limited (OM642 Mercedes) after driving 30km shows failure in the fuel sensor past failure P2264 Fuel/water separator sensor circuit.
I have already changed the sensor and filters and use only good diesel the obd always shows the same fault as before.
could you give me some guidance?
it makes me crazy
Give me a tip Please..
Work for every om642
Car goes vrooooomm
I thought my headphones were broken when i couldnt hear the intro..
same here
same here also
I legit went and checked everything xD
I’m looking for help. Can you please tell me the exact resistor number please. I’m having the same problem with my 2008 Jeep. The dealership asked for 1200$ US.
Still have the issue with mine limp mode all the time after few miles
I had my swirl flaps removed years ago, already had 3 children
Does it still drive okay with this bypass?
Hello, where can you buy this plug? Thanks in advance.
The link to buy this is longer valid , can i still purchase this somewhere?
Why didn't you attach the resister as you advised..
What does the swirl flap motor even do anyway. What part of the engine does it connect to/control?
They are used to make the incoming air swirl around at certain engine speeds, which helps improve the mixing of the air and fuel, increasing efficiency and decreasing pollution.
They are almost always attached to the inlet manifold.
How can I get that adapter? Any links?
Full Pro 👍
Your link for the emulator does not work. Could you please let me know where to get one in Canada?
the screen text said it helped reduce emissions . will it pass the MOT emissions test like that ?
Probably, the tests on diesel engines are extremely lenient, hence the state of the air quality in most cities these days.
