3.0t TDI AdBlue Heater Failure ~ P205B Check Engine Light

[@HumbleMechanic]

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

[@lukasmeyer1992]

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.

[@mattkrazit6414]

TDI content always appreciated. 👍

[@HumbleMechanic]

@@lukasmeyer1992 WE never got the 4.2 TDI! but the 3.0 is pretty solid!

[@TraceyAllen]

my TDI is in the dealership with low comp. waiting to see what happens!

[@bcredeur97]

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.

[@wyattoneable]

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.

[@gordonfarnham-zc6kw]

Today I followed this information from your video to remove and replace the ad blue reductant heater ,completed with ramps on the driveway , all went to plan took around 2.5 hours from start to finish, no real issues, thank you Charles

[@pwilson920]

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

[@thatsabadmrkitty]

Was able to swap it out within a couple hours thanks to this detailed tutorial. You're the man. Love the Touareg content

[@MartinBalle7]

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

[@psnmadracer27]

I feel the same way, to be honest

[@ernie334]

Deleting is probably the better solution in the long run

[@PerfDayToday]

We have a ‘14 TDI Touareg. Nice to see these TDI Vids.

[@MacLeanLunko]

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.

[@DesolationTech]

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!

[@DJNokem]

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!

[@HumbleMechanic]

I appreciate that!

[@sauls8250]

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

[@VWRalf]

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.

[@wblbearshockeyfan07]

Love this ask! Would definitely appreciate a vid on this.

[@gilbertocrisostomo9857]

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…

[@RooflessVW]

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.

[@pilotd]

that takes way too long and is equally as messy.

[@baileyphillips1519]

Great video Charles, thanks! Would love to see more TDI content. Especially CKRA or CVCA repairs if you come across them.

[@AndyDento21]

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

[@victordiez2085]

P20E8 and P20EE FUCK THEM

[@mcpaintball]

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.

[@teovm]

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.

[@kevinbarry71]

I enjoyed the video. I love that Volkswagen technical service bulletin. Replace the whole thing. Thank goodness for factory info

[@lovevwltd7114]

Would be great to see something on repairing the keyless access system.

[@theryanwitski]

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

[@HumbleMechanic]

Wow!!! That’s awesome

[@KT-en8pq]

Right. Diesel gate worked out great for me too.

[@nicostenfors5690]

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.

[@HumbleMechanic]

nothing says saving the environment like expensive systems that fail, and tons of cardboard and plastic to house the fluid it requires.

[@nicostenfors5690]

@@HumbleMechanic Yeah, and it's nasty corrosive stuff. Leaves a big white stain on concrete floors.

[@alf3071]

that stuff probably dries up and clogs the pump or the pipes

[@dominikszafran5514]

how about golf 7 tdi adblue injector leaking common issue on these thanks! love the TDI content

[@HumbleMechanic]

Ill have to find one locally not covered under warranty.

[@1polly]

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

[@TheNotimprezed]

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.

[@bcredeur97]

[@jettaguy2]

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 ✌

[@turgeo2004]

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.

[@neil3858]

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.

[@lijoima]

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?

@15:34 "go back connect all the connectors that we unconnected to make the connections for connecting" LMAO i died a few times...

[@radoadamov9201]

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!

[@HumbleMechanic]

That’s very much not the case. It does have to meet the proper spec. But it doesn’t have to be VW

[@radoadamov9201]

@@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!

[@Flyingspann3r]

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.

[@b1r260]

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.

[@HumbleMechanic]

Ugh I’m so sorry. :(

[@mizer89]

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.

[@jsejosh]

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

[@claytonwodiany]

Great video, thank you. Was the exact same for my 2014 Cayenne

[@PaulMurphy-o1j]

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...

[@ChrisFaulkner]

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.

[@saarekas8177]

[@camerondeacon4450]

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.

[@davidwestra8181]

Would this same fix potentially also address a P204B code?

[@fortypath22]

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?

Thanks again for you videos Charles.

[@wblbearshockeyfan07]

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.
