3.0t TDI AdBlue Heater Failure ~ P205B Check Engine Light
Вставка
- Опубліковано 25 сер 2024
- A VW Check Engine Light? NO WAY! Today we repair a TDI Touareg with a P205B code for reductant tank temperature sensor. I will show you how to replace the Adblue heater in a 2015 Touareg. This should be similar on Audi Q5 and Audi Q7 3.0t TDI. The 3.0t TDI is generally pretty reliable, but Adblue and DPF issues can happen. This issue may also be covered on TDI warranty. Before you DIY this repair, check warranty status! Thanks to @BlueDEF for partnering on this video.

So many of you guys have been asking about TDI stuff. Hopefully this video is helpful and does well. That is the biggest motivator LOL
I did not know they actually sold Diesels in the US. For the Touareg a 3.0 or even better 4.2TDI is the best engine anyway.
TDI content always appreciated. 👍
@@lukasmeyer1992 WE never got the 4.2 TDI! but the 3.0 is pretty solid!
my TDI is in the dealership with low comp. waiting to see what happens!
Love it! I have the same Touareg. Bought it because you never work on it, so it must be reliable (lol jk I did more research than this!).
I do want to see more content on it though! Love knowing the ins and outs of the cars I own.
Lots of steps involved but now that you have explained the process I believe many people could do this themselves and save lots of money. Great job Charles.
I completed this repair today with the help of your video.
Thank you for saving me thou$and$. Trickiest part was separating some of the wiring connectors. Took about four hours working slowly and carefully. Cheers
Glad to see a Tdi video where the fix isn't just deleting the emissions stuff. I mean there is a reason why it's there. In a time when we are moving to electric or hydrogen cars, I think it is important that we keep emotions down so that we still can drive gas and diesel cars
I feel the same way, to be honest
Deleting is probably the better solution in the long run
Was able to swap it out within a couple hours thanks to this detailed tutorial. You're the man. Love the Touareg content
Always something to learn from this channel. I'm not even that big a VW fan but the information is worth the watch regardless. Keep it up!
I appreciate that!
We have a ‘14 TDI Touareg. Nice to see these TDI Vids.
Great video Charles, thanks! Would love to see more TDI content. Especially CKRA or CVCA repairs if you come across them.
Hello there very nice video. As here in Europe we have a lot of those diesels it's nice to check a video of this kind.
those fuel pump tools are amazing for not smashing the plastic up i have the two bar one (bar either side with a 1/2 in the middle to rotate) makes it tons more efficient!
I worked for Citroen/Peugeot as I'm from the UK and being French the urea systems constantly broke so did a lot of diagnoses and tsb bulletin work on them..... sometimes replacing the full tank as in their infinite wisdom made the pump integral to the tank! At least VAG group made this pump separate.... I reckon I will one day work on one of these so this video has educated me for this.... Thank you sir. As a tech still always learning and done it 20 years now
P20E8 and P20EE FUCK THEM
Thanks for posting this video. I just changed my Adblue heater tonight, took about 2.5 hours, by myself, with just putting the rear of my Touareg on ramps.
If you haven't done it yet, could you go through cleaning the soot out of your intake, throttle body, egr pipe? I've cleaned the throttle body a couple of times, but haven't gone as far as removing the intake manifold on my Touareg. Would be interesting to see the whole process by a pro.
Love this ask! Would definitely appreciate a vid on this.
My top tip is to buy the 1L AdBlue bottle from VW/Audi and cut the bottom off.
Use that as your funnel. It has a check valve built into the head that screws on so you can't overflow your tank.
that takes way too long and is equally as messy.
Would be great to see something on repairing the keyless access system.
Excellent video, thanks!
My 2014 Sharan has the "P205B Reductant tank temp sensor - implausible signal code 9688" error message on VCDS. My question is: Can the sensor be replaced on its own, or do I have to replace the whole AdBlue tank heater unit like in your video?
Thanks
I have a 2014 diesel passat sel with 64,680 miles and the check engine light just came on with p205b this video helped me understand the system and as soon as I get it fixed I'm selling this car and I'm going back to my Japanese cars because I know how to work on them. This volkswagens evething is a pain in the knee to work on
Back at it again. keep up the good work..
thank you!
Got code P208A on my wife’s Cayenne, Porshe was going to charge 3 hours to drop and check what’s faulty, thanks to your video I dropped the tank in 45 minutes, now the fun part, I need to check wiring pump and heater… full of cristallisation everywhere…
The warranty saved me 9.5k with a crazy repair on my wife’s Q7. Dieselgate was the best thing that ever happened to us lol
Wow!!! That’s awesome
Right. Diesel gate worked out great for me too.
Humble, thank you for taking time to post all of these great vids, im not mechanically inclined and don't have your skills & knowledge appreciate seeing all the technical stuff. I have a 2015 Sportwagen 2.0 TDI sitting at a VW dealership one year still waiting on the def tank, lucky me im still under warranty, pretty frustrating. Are there after market companies marking this tank for future problems when im out of warranty ? Do I stay with TDI or do I go ? Thanks for your time man, subscribed ✌
I have a 02 1.9 tdi golf with 322k miles. Would love to see some videos on that. Great job!
how about golf 7 tdi adblue injector leaking
common issue on these
thanks!
love the TDI content
Ill have to find one locally not covered under warranty.
As a farmer and a farm machinery mechanic theese AdBlue systems can be very expensive and annoying. New harvesters have AdBlue and regularly fail because harvesters sit over the winter, here in Finland we regularly see -30°c temps so freezing is common.
nothing says saving the environment like expensive systems that fail, and tons of cardboard and plastic to house the fluid it requires.
@@HumbleMechanic Yeah, and it's nasty corrosive stuff. Leaves a big white stain on concrete floors.
that stuff probably dries up and clogs the pump or the pipes
This is awesome. Got a 2015 TDI that I bought from Copart, so it's not under warranty. But doing it myself also means they won't neuter my car with the ECM mod that they're supposed to do.
MORE TOUAREG TDI CONTENT PLZ!!!
I need to do some big maint on this one. Its going to depend on how well this video does. If it does okay, I will. If it flops, I have to commit resource to other projects. :(
Do a transmission service!
I enjoyed the video. I love that Volkswagen technical service bulletin. Replace the whole thing. Thank goodness for factory info
Great video, thank you. Was the exact same for my 2014 Cayenne
Great video again Charles 👌. Always informative and fun to watch. I always take away a new word from each of your videos, “glurble” was the pick from this one 😄. Good work my dude 🤙
Charles, the one VW owner that looks forward to any new check engine lights on his cars: "A new video opportunity!"
I use Blue driver code reader scanner, have been getting that code past 6 months, I just keep resetting it lol. Problem is winter is here and well I am not really sure if the adblue heater works, or if it was just a sensor glitch, so I i will order the part on Amazon found it for 96.00 the main heater part. Mine is a 2014 Passat TDI.
Awesome video! Thanks!! The dealer just told us on our 2011 Toureg that we had till 128k, or end of 2024. We're at 119k, so they're going to do it this time! (I hope...)
Thanks for posting this video! I have a 2016 TDI Touareg and one morning, I notice my exhaust tips are cloudy followed by a check engine light. I ran a scan with VCDS and there were two codes, P229F & P20EE. I pulled the DEF injector and noticed right away that the nozzle had dried DEF. I cleaned the injector, reinstalled, cleared codes and have not seen the light again. But I still get some cloudy exhaust tips, but no check engine lightMy suspicion was since the crust on the injector was disrupting the spray pattern, it kept spraying continuously while at the same time a sensor was not detecting for the correct amount of spray that it was looking for. Also, while I had the DEF injector pulled, I looked inside of the exhaust hole, It has tons of buildup inside. Have you ran into this issue? Thank you for all that you do.
amazing content as always Charles! can't wait to see more
Love the torque spec..
GuudNtight !!
I miss my '15 but traded it when I needed space for 3 car seats. It also coincided with the odometer hitting 119,000 miles. I ended up with a crew cab 5.0 f150 and thought I would miss the mpg but now it's actually cheaper to fill a 36 gallon tank with gas than the 26 gallon diesel tank and has the same 600+ mile range.
Crazy world we live in rn lol
That spare is insane looking!!!!
KNOWLEDGEABLE HumbleMechanic
Tutorial brilliant video amazing footage 👏 👍👌 Thank you very much helpful information video HumbleMechanic
From Nick Ayivor from London England UK 🇬🇧
I foresee a lot of these dieselgate TDI’s becoming “off-road” vehicles once they’re out of warranty
I sure hope
Got a reductant heater code on a diesel Transit 250. Same repair, but only takes 1.7 hours, because big-ass work van.
Awesome vid. I didn’t get the check engine light but the “low ad blue” message. After adding this time around the message didn’t clear on the dash. Would this mean a sensor in the tank went bad? And if so can that be replaced or better off replacing the whole tank? Thanks in advance to anyone with some insight.
I don't suppose you know if the TPMS module has any wiring associated with the connectors you highlight @ 5:20 - have intermittent power to the module and have discounted fuses so now musing high resistance or dislocated pin in a plug but can't think where to start looking...
Great video as usual, however according to my local Volkswagen dealer in Salt Lake City you can not use any other AdBlue but the original one they sell. A very close friend of mine got a bad experience with that. He was buying the fluid at "Costco" thinking all fluids are the same. Then he got a check engine light on for bad quality of the DEF and not ODIS, vcds or any other tools were able to turn off the check engine light. My friend went to the dealership since it's under warranty and apparently they have a way to test the fluid and told him they won't cover this repair. He ended up draining the non original fluid out and filled with the original AdBlue fluid and the error actually cleared itself immediately after. Since then I only buy the original one and keep the receipts so if that happens to me, they can not play the same game. I know I can get free refills until the extended warranty expires, but they told me 1.5-2 hours wait time, so I just buy it. They will use any little thing to deny warranty work and I am not giving them any chance to win. Just my opinion (experience) and hopefully more people will be aware of this now.
Keep up the good work mang!
That’s very much not the case. It does have to meet the proper spec. But it doesn’t have to be VW
@@HumbleMechanic, unfortunately for him they documented that he was using non oem fluid and even call to Volkswagen of America didn't helped. The fluid in question was exactly the same as yours, widely available at Costco, gas stations and car parts stores. It's very hard to fight the big corporation and in his case was totally not worth it. Just don't give them a chance to play you when it's in your control, have a great one!
I agree with@@HumbleMechanic you don’t need to go to the dealer to buy their AdBlue. The required spec is 33% checked with a spectrometer. That is what the VW system is looking for when it does it’s quality check. Some places in the UK have been found to be watering the fluid down to improve their profit margins, but it just results in an error code and probably an expensive bill if it is still under warranty.
To be safe, make sure you buy a good quality brand in a sealed container from a recognised petrol station or parts supplier and you will be fine. Look at the spec number on the side of a VW AdBlue bottle and match it to the spec you want to buy.
After all, Volkswagen Group (VAG) don’t make the fluid themselves, someone else does.
Agree with everything, however having lived in several large cities, SLC, hands down has the worst VW Dealer service network. Humble Mechanic has helped me circumvent these sorry excuses for dealer service.
Ugh I’m so sorry. :(
I had the NOx sensor and reductant tank sensor replaced by VW service (Under warranty) on a CKRA Passat 2013. Got the car back from the shop and as we left, the ABS system started barking. took it back to VW and they said the pump needs to be replaced ($4500). ABS was working just fine before. I've seen a video where you run out of AdPiss and it locks the system down, the ABS starts going off, even after resetting the SCR lock. Something is going on here and i've tried to trouble shoot the issue (wheel speed sensors are working as I see them thru VCDS). Don't knmow what to do other than replace ABS pump and control module and recode it.
My Q7 has this problem right now.
Great detailed explanation on this job! I did tackle this last weekend and went very well however I now have an add Adblue message that started and stated 160kms till no engine start. I don’t have VCDS however would a scr reset fix this issue?
The only fluid that's in my spare tire well is rain water 😅
More diesel Audi and Volkswagen please 👏🏻👏🏻👏🏻
QUESTION. Adblue light came on at 1500 miles. Check engine light come on 2 days later and I figured the adblue was the reason for the code. Filled DEF at 1000 miles with 2.5 gallons and figured this would also clear the code. Adblue still says to refuel and check engine light still on does this mean I need to replace the entire unit?
Dear Volkswagen, why couldn't you just add a top access point in the trunk above the ad blue tank 🙄. Digging into mine this weekend
I have changed thouse on porsches many times.
This video gave me PTSD from doing the fuel pump on my old MKIII Jetta. Trying to get the ring off was 🤬🤬, but getting the main section of that fuel pump to lock into the bottom of the tank was 🤬🤬🤬🤬🤬. All done with the tank still in the car because removing it looked like way more work, lol.
My Cayenne has the same issue. Will anything bad happen if I just live with the CEL?
My vw touareg tdi just failed but is it hard to delete
Yes.. I as well would never delete my DEF, DPF or EGR and then tune it for better milage. Nope, no sir! 🤔
If I were to delete this would I need a tune? Wouldn’t it be better overall … off-road of course
Asalamaleikum. Greetings from Kosoves.Thankyou USA.
Is this the same process as a 13 Porsche cayenne?
notification squad!🔥🔥🔥
WOOO!!
Where did you purchase the temp. sensor kit? Thank you
Any chance you have any info on the Passat TDI, with the same code?
How much would this job cost at the dealership?
4:08 if only i can have many Charles working on my Mk7R during mods and servicing.
I have a Tiguan MKII 2.0 TDI Engine EA-288 2019 with AdBlue tank, I was told that AdBlue should NOT be in the tank more than 2 years, if that was the case the tank should be drained. Can I drain the tank by myself or should I take it to the dealer (there’s a discharge valve that I can use)?
New subscriber! Thanks for the video content you add! Quick 2022 Golf R question for you...do you know the location of the Harmon Kardon factor amp in the new Golf R?
There few vw in uk first time you refill it the sensors dies . It not to occur if garage dose it but at home user seem to set it of. Has put me off upgrading. Far im concerned you only need air con dsg and upgrade alpine media player. Every thing else on offer is a waste of time
Instead of bolted back up, maybe “nutted back up”?!? Lol hahaha
I had 2 of these fail in a 5 year period on my 2012 TDI Touareg.....there was a RECALL FYI and they should replace.
...and of course, you explained it and I commented before watching the whole video! #yeahinternet
Bahhahaha
spreading lube on connectors - need a note, what kind of lube, otherwise people may damage wires/pins
I’m glad you posted this video. It only pays 2 hours and I’d rather not do all that!!
Next question, is this header on national backorder like it is for heavy duty vehicles.
Dear mr humble. I have a mk6 gti sitting in my driveway rotting away bc i have no clue whats wrong with it. I was told the engine has no compression. Got one laying around? I miss my baby. I need her back in the road
Would this same fix potentially also address a P204B code?
Hey . I have a 2107 vw amarok pick up truck . Some times the fuel gauge stop working and the needle goes all the way down , and the low fuel light doesn't turn on , distance to empty says - - - instead of 0 . I turn the key off and then turn on and the gauge works again and the distance to empty says the number . No fault code showing. Do you have any idea what can it be ? Thanks !!! Great vids !!!
hi very informative videos can release advise my mk1 hold when rev down the engine seems to vibrate meaning once i Lev the trottel the engine vibrates had guys check it out one say valve bounce one say fueling not returning very fast one said to much of fueling on the map thats one what will ur input say thanks
Pretty sure the regular mechanic and home owner cannot buy a dealer level computer that can work on any Def system on American vehicles and trucks. Pretty sweet that we can service our own VW’s and keep them going.
I would like more touarer videos, but I have a 2014 gas, not TDI.
I had no idea this technology existed in tdi's, very interesting. What is your opinion on sencond hand vw's, tdi vs tsi models, from a reliability and longevity point of view? Are there any partcular models/engines in the last 5-8 years that you would especially recommend from a reliability point of view etc. Particularly interested in the golf, jetta and tiguan models. Thanks again for you videos Charles.
I've had a golf TDI for the last 3 years and 50k miles (for a total of 100k miles). Never done anything except routine oil and filter changes (oil plus fuel). I also do a fuel additive every 5k to keep the injectors healthy since diesel quality in the states isn't all that great, and often times have a larger than spec'd % of biodiesel. Engines are rock solid but the emissions systems are always the first thing to have issues (fingers crossed nothing yet). I love it I average 41-45 to the gallon spring through fall with a lot of 75+ mph driving. Worth the extra dollar per gallon IMO.
I have a 2011 Q7 TDI with the CATA engine is there anything I should keep in mind, I had two injectors replaced under warranty a few months back.
Will it hurt to drive my Passat before I get it fixed I have a P205B lighting up just now
HB= is it worth rebuilding a 957 cayenne VR6? I think its the 32v option. I would like more HP out of it if possible. Cayenne is paid off, just wondering what you advise?
Great video! I love the content!
dumb question time! why the WD before disconnecting the cables?
Helps lube them up to make it easier
Had this done under warranty a few months ago and it failed again but now I'm over 150,000 will the part have warrenty?
Has your Touareg needed the manual regen? My 2012 Touareg tdi was in limp mode and the only resolution the dealer had was the manual regen covered under the warranty.
That tool is awesome
How about the level sending unit for the DEF. is that apart of this "repair kit" as well? i have the issue where the tank is full yet it thninks its empty... been debating on getting the 3C0 sensor or this unit to remedy the situation. riding around with a laptop to reset the scr lockout is getting kind of annoying haha.
Thank god i have an old tdi with non of that emmissions crap
Would LOVE to see thoughts on v12 TDI
I’ve never seen a v12. We had the v10 in the US A while ago.
Check out Dark Side Developments channel. They are out of UK. These V12 TDIs were way more popular in Europe. Sick engines but you would have to be nuts to own one, or really stinking rich.
I'm assuming you get this constantly, but I have an 09 Jetta TDI just off warranty. I'd love to see a video of you doing a delete. For off-road use only, of course!
Lol I am not sure I’m willing to put my out there for the epa to rail me
@@HumbleMechanic the gubment wouldn't go after the little guy, would they?!
I don’t think so. But those rollin coal fools kinda wrecked it for everyone
@@HumbleMechanic no doubt!
Humble… the picture for this video!!!!😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
LOL ;)
@@HumbleMechanic 😂😂😂😂 love it bro!!!
Does Malone stage2 tune will turn this cel off? I am just out of warranty and probably will go that route instead of fixing it
I’d confirm with them, but I think I may
Are Xemodex DEF system repair parts worth it?
10:59 I'm thinking about how many fuel pumps that tool must be effective on. It might pay off for the professional to own one.
@22:32 do you know by any chances what are the specs of the wheels? I too agree they would fit nice on a car! and/or how to shop a spare tire!
Where did you get the fuel pump tool ? Its wicked
What's it smell like? My TDI never had that
I want one of these to tow my other POS to shows haha cuz it wont make it on its own
How come you did'nt use your homemade DEF funnel jug? i made one for my old Sprinter after watching that video.
Don't need it now since I've upgraded to a Man TGL 8.220 servicetruck.
I have no idea where its at LOL
Wow😳 nice Work
Thank you so much 😀
who makes this 9:45 hex socket set?
