- I got this engine management fault code P202A, which means "Reductant Tank Heater Control Circuit / Open". So there is a problem with with the heater for AdBlue fluid.
This is the video how I fixed it and solved the problem.
Here are some useful links:
Here's a link to relevant page at our website, also available in printer friendly PDF format:

Repair kit (replacement parts) - you can get them from your local dealership or from eBay. Please, check the price from dealership, because it can be not too different to those on eBay. Please check compatibility with your car (especially if it's not VW Sharan/SEAT Alhambra). Anyway, here is the link to eBay search results that will give you part number and few choices at a good price:

i watched this once and that was enough instruction to replace the part myself. Thanks for the great instruction! took about 1.5 hours start to finish
It took me longer :)
Thank you so so so much for putting this video content together, our 2012 Alhambra has thrown an error code for the AdBlu heater (reported by dealership), however Seat want £695 for the part and then £180 plus VAT to replace…
Thanks to your video I will most definitely be doing this myself.
You have a new subscriber here too 👍
You're welcome, I hope it helps
Hi, Thanks for the video.
My 2011 Seat Alhambra threw up an engine management light and my VCDS software showed fault P202B, which indicated the adblue heater had a sort you ground.
Checked with Seat UK that the VW part code you showed in the video was the same for my Alhambra, and it was. Ordered one from ebay supper in Germany for £170 including postage, it arrived 4 working days.
All fitted and car back on the road in about 3.5 hours.
Saved me a packet of money and the joy of beating the dealership system.
Interestingly found out that VW cover this part under warranty, but the idiots at Seat deny there is a problem.
Thanks again for the great video .
Thanks Nige :) Glad if it helps! VW dealers in UK also deny the problem - recall could be applied for US only..
So useful. My AdBlu heater packed up and the local garage wanted £750 to fix it(inc. VAT & parts). I followed the guidance in this video and did it myself saving £500. Excellent video - thanks so much.
You're welcome Paul :) Glad if it helps.
Another brilliant and reliable video saving me a small fortune and keeping my old vw ticking along nicely. Thank you so much.
You're welcome, I hope it helps 👍
Love your videos. You really go the extra mile for your viewers to properly explain. Great job
Thanks :)
Lifesaver! I just got a quote for replacing my Sharan 2012 Adblue heater, 1200 euros (12 000 NOK). No effing way. So I'll watch your video a couple of times and do it myself.
You're welcome
My engine light came on and got the P20BE/P20BD engine codes on my 2014 Sprinter. Took it to Mercedes to confirm... was quoted $2,976.50 to replace AdBlue Heater Element. Found Bosch (OE) replacement on Amazon for $246.59. Will replace myself thanks to your video. Thank you!
You're very welcome 👍 Hope Sprinter is not too much different.
Hello, after replacing the timing belt I installed this repair kit following your video, BIG BIG thanks for your effort and sharing it. More beers!!!
Definitely going to Madrid now 😊
Youre a really good mecanic, great that is so detaljed and you comment on things that are important, graet JOB MATE!!!
Thanks, but I'm not really a mechanic 😉
Maybe this is why my videos are so detailed..
Amazing video, so clear, I just did this myself. The only thing I noted is that my kit came with new seals for the pump, check if your kit does and make sure to add them if needed!
Great video sir. I am adding myself to the long list of people you've helped do this job and save some cash. Very much appreciate the time you've taken to make the video, absolutely spot on. Thank you!
Thank you very much 😊
Comments like yours keep me going 👍
Thank you very much for your times and brilliant videos. We loved every single of your demonstration video in every single part of the VW Sharan.
Thanks for your support Dinh! 😊
@@wawayltd No. Thank you my wonderful friend, and we know for sure that if you are open your business, there will be a lots of people would come to have their car fix, and we will be your first! 😂😂😂
Thank you so much, I saved at least 500 €... Please don't stop to do this !
Thanks, I'll try my best 👍
Thank you very much for showing how it is done. You've helped me do this better and faster compared to a blind approach. All the best!
You're very welcome :)
Greetings from ROMANIA. Thx for the great video. It helps a lot
Cu plăcere 😊👍
just repaired my 2012 sharan with p205b error code. followed your video step by step and now everything is working perfect. easy piecy :-) thanks. great video and great explained. saved me a bunch of money.
You're very welcome Mr Johnsen 😊👍
I have the same problem with my Seat Alhambra 2011 (P205B). Can you please tell me the code of the part you changed? Thanks
Looks like your fault code also points to AdBlue heater. Part number is in the video - 20:40
Finally got around to it! Not difficult when following your instructions, just fiddly here and there. Big thanks from me to you, dude! Oh and the rubber filler thing definitely works best being put in from above at the end of the process.
Glad it helped. And thanks for the advice on rubber filler, I don't think I have it in correct position till now :)
Please, keep on doing these nice and tidy videos. Thumbs up!
Thanks :)
Top Man,very good Macanic, Excellent Teacher of Automobile. Best Macanic. Wish you are Best my friend. I can't keep up with modern car. I wad good with 60s, 70s and 80s cars all the best 😃👍🙏
Thanks, Abdul 👍
Just changed mine too. Thanks to your video with no problems. Thx
You're very welcome 👍
Amazing I had a leak in mine and used this video to get the bumper off and drop the tank. Helped no end.
You're very welcome 👍
turn the pins on the tool over to tighten so you are dragging the loose arm not pushing it Great video!
Thanks, I'll keep that in mind next time 👍
Thanks a LOT, this video is very well done with clear explanations. Saved me a lot of time. Good job!
Thanks Marc 👍
Excellent and detailed procedure. Thank you !!!!
Hope it helps 👍
Excellent video, was very usefull when fixing the problem with the Sharan, keep up the good work.
Thanks, I'll try my best.
Thanks, mate.
Did the job today and it worked out well thanks to your video...
You're very welcome 👍
Thank you sir! Your videos helped me realize that I can fix anything mechanical on the 2014 Passat I’m buying. God bless
Thanks Lawrence 👍
Great video
My parents car just came up with
P202b so probably thinking I need to do the heater
Easy peasy 😷👍
Thanks for the video, helped me fix my Touareg today.
You're welcome 👍
Hello! Thank you for your video. I need to ask something. After you replace this heater system with a new one, as you did. Does it need to be set up or programmed with a VCDS software? Or is it just a physical replacement with no need of software programming? Waiting for your reply when possible. Thanks
Sorry, just discovered this comment. No, it's "plug and play", no need for software... Better late than never 😁
I can't thank you enough for this video. It would seem that our Sharan's have the same problems cropping up. I have just received my new AdBlue heater, and I will be following your instructions closely :)
Thanks Keith, glad if it helps :)
My Sharan is coming up to 300K miles :)
Thanks for your video i did this repair today and it worked great. Keep up the good work!
You're welcome!
Thank you for an informative video. Changed the heater on our Sharan yesterday. No surprises or problems!
You're very welcome, glad if it helps 😊👍
Thanks👍 greeting from Slovakia
You're welcome 👍
Thanks a lot. Thanks to you I saved 2.500 euros. hello from germany.
Bitte sehr, Dmitrij 😉👍
2.500?? German mechanics are greedy... They made this car! Should take a bit of responsibility 😁
@@wawayltd thank you very much 😁👍
@@wawayltd subscribed to your channel for a long time and I'm watching how to make this car. thank you keep going. although I do not understand English, but my eldest son has to translate for me. health to you and your loved ones. Best regards, Dmitry.
Thanks you very much for this good job , top vidéo. Just don't miss 2 little seal under pump, thanks
Thanks 👍
Thank you from Germany. This is Super.
You're welcome 👍
And again, thank you very much, I love your VW Sharan videos.
You're welcome again 😉
Like always you made a great job.I made successfully the work to my passat thanks to you. When do u make a video about the fluid brakes change and coolant fluid change. Thank you!
Dan Gabriel Thanks :) Maybe I'm wrong, but I don't normally replace those fluids. Every time when I replace cambelt and water pump, quite a lot of coolant comes out, so I consider it as partial replacement. As for brake fluid, I think I should do that eventually - I have a pressure bleeder. My previous car, Audi A6 has done 409.000 miles on the same brake fluid :) My Sharan currently has 220.000. But, because I want to keep it perfect, I might do it at some point.. Maybe spring? Don't know :)
Thank you for this perfect explanation!
You're welcome 👍
Hello, after replacing the part, it must be programmed. Thank you very much for your answer.
Hello, no it doesn't need programming.
Thank you for your video and all the details you provided. I successfully managed to fix the problem. Many thanks.
You're welcome, Alecandre :) Glad if it helps.
Great job. Next week I have to replace it in my Benz.
I hope this would be fairly similar.
Hello, I have Seat Alhambra 2014 2.0 TDI 103kw, and PC says codes P203B and P205B. Do you think that by changing heating system it will erase both errors?
I think that Sharan and Alhambra are almost the same cars :) thanks for answer and for great instructional video.
Hi Kubo, till today I thought that heater, level sensor and temperature sensor are in one piece. Now, after good look at diagram in Elsawin, I see some evaluation unit, which is not the same thing. I can see it in my video, I didn't take it out. Probably that could be the thing... But I'm not 100% sure, because I'm not professional.
You know, I can recommend good website with manuals from manufacturer, you can download well organised PDF for your car about everything. Check this out:
erwin.seat.com/erwin/showHome.do
My 2011 Sharan recently gave me P203B: Reductant level sensor circuit range/performance.
So, something wrong with the AdBlue level sensor. So I filled it up, after that, the error was gone.
Today it gave an error out of nowhere: top up AdBlue, no start possible after 1000km.
The check engine light came on aswell, but I don't have a device to read the error code. But I suppose it is still the level sensor giving me trouble...
That's why I watched your video, to learn how to get the tank out.
And I watched other videos of you aswell! F.e. the timing belt. Thanks a lot!!
Can you tell me if te level sensor is in the heater assembly? Or is it a seperate device placed in the tank?
I am not sure where exactly is the level sensor, sorry. I don't have that car, and I've lost my manuals for it. However I can recommend a good website with manuals from manufacturer (you can get access for like 7 Euros per hour, which is more than enough to download well organized PDF's for your car), also one pretty good active Facebook group.
Here are the manuals (make sure you select all English, unless you prefer your manuals in German ;) ):

And here's the Facebook group:

Hope it helps.
Great video. I have this job to do tomorrow. It will be easypeasy now. Thanks
It easy. Thanks 😊👍
Thank you! Your video greatly helped me!
You're welcome 👍
You do not have the impression that one plastic band is under the pump crushed (40:37) cool video.
As far as I know, nothing was broken. It appeared to be easy job to do. I should've made the video a bit shorter :)
Thanks for your Video. Could I ask a question that how to drain the adblue easily?
Sorry, never had to do it.. Use some hose?
An excellent instruction video. Thank you.
Steve, you're very welcome 👍
Super Video, alles gut erklärt!! Vielen vielen Dank
Danke 👍
Thank you for the video, yesterday I change the heater in good condition.
Thanks Alexandru :) Glad if ti helps.
Merci beaucoup, vous êtes le meilleur
Sei stato molto utile grazie per fato questo video
Excellent vid, thank you!
My Sharan is also a taxi and I have the "P205B Reductant tank Temp sensor - Implausible signal" code 9688 showing on VCDS.
If the sensor is faulty and nothing else (which I don't know at present), can the sensor be replaced easily - on its own - without having to replace entire tank?
Thanks, unfortunately I've lost all my documentation on Sharan, so I don't know where temperature sensor is. I suspect, it could be part of a heater unit, but I'm not 100% sure.
Hello
Please I would have a question.
My Sharan sends the p205b fault.
the adblue reservoir temp reads 69c although the ambiant temp was 10C and motor was stopped..
Do you know if it is armfull for the antipollution system if the car runs for just a hundreds of km (i need to drive far away and won't be able to fix the issue soon...will be reseting the fault) ?
Your have shared a great video ! it will definetly be usefull for me !
many thanks!
If there is a problem with AdBlue, sometimes it gives you mileage countdown. You need to make sure not to exceed that, otherwise there will be trouble starting the engine.
That's about all I know.
As for your fault, I don't know what's wrong there, sorry. I'm not a mechanic, just an enthusiast.
Mine 6 years old AudiQ5 has addblue problem as well. The position of the AdBlue tank and pump is similar to the Sharan and the rear bumper has to be removed? Coud you refer to this. Before you started were you shure that the heater element is your problem, just by reading the error code? I done error code readings, but they are just nut clear for me. It speaks about pressure problems?? It was a great job.
I had a fault code specifically pointing to heater, that's why I replaced it.
What fault code do you get?
Excellent video!
Thanks Steve :)
interesting lesson. So learning is not necessary after the work has been carried out?
Sorry Najim, I don't understand your question.
Hi I had a code for level sensor And pump intermitten . So I changed the heater pump and problem still the same . Any advice on what to do next ? Do u know anything about the two control units that are attached to this unit ? Thanks for any help
Sorry Peter, currently I can't help as I've lost most of my manuals. Pump sits on a top of a heater. I think level sensor could be somewhere on a side of a tank. I need to get back to it, but can't find any time. Sorry.
interesting lesson. i have error code P205B and heard this is the problem too. So learning is not necessary after the work has been carried out?
What learning? Do you mean VCDS adaptation? It was "plug and play".
Watching your video from Australia. Thanks for sharing. Now you have old plastic locking ring/nut. Could you weld up some sort of special tool for next one?
I have a tool... Don't see much point of making new one.. if I understand correctly.
These failures are endemic on vag cars and vw should be recalling affected cars and replacing these duff heater units free.My seat alhambra's went and I had a HELL of a job getting them to replace it under warranty-but in the end they did.They wanted £420 to replace!
Realy good jib, and I used your Video to change the heater on my Sharan also.
But anyway I have a foulty on Display with Adblue rest 0km
Is there a reset necessary???
If it's all the way to 0, I don't know how to reset it, sorry. Try asking here:
facebook.com/groups/1463201880401563/?ref=share
I've got a P202A error also, however my adblue fluid level was low too. The bottle and spanner have been flashing so I topped it up fully however the spanner and bottle is still flashing and CEL is on. Are these systems linked?? Are you anywhere near Manchester?? Thanks
In my experience this AdBlue system is temperamental. I hate it. Try to clear the error. Also put ignition on for 30 seconds without starting the engine. Maybe give it couple days to realise that it was topped up, but if there's countdown - do not let it get to 0, as it may become more complicated.
If none of that helps, I would go for heater replacement. I can't promise it will solve all issues, it's just what I would do if it happened to me, and I'm not a mechanic... Pretty far from Manchester, in Bristol.
@@wawayltd thanks it cleared after driving on the motorway however p202a remains open circuit reductant heater. I suspect heater but have had another cat converter changed and before that EGR valve and reconditioned the turbo. These adblue systems cause terrible problems.
From did you get adblue heating element repair kit thanks
Dealership or TPS.
@@wawayltd Thanks for fast response
No worries. Good luck with the AdBlue 👍
Exellent.. the video really helped
Good to know that it helps 👍
Great job!! After waching your video it seems easy to do, very well explained!! I ´ve vw Sharan 2011 2.0 Tdi (103) engine cff .Do you know If the same heater for this car? Thanks
Thanks :) It should be same - my car is 2012 and CFFB engine.
Urgent question: Do I need to bleed the pump when I install a new one, or is it sufficient to just turn on the ignition and wait for the pump to bleed itself?
I can't find a bleed screw on the pump. Should I bleed it manually with a syringe?
thx an lot!
Sorry for the late response to your urgent question... I didn't have to bleed it, and I don't remember the manual mentioning something about bleeding.
For some reason, CZcams hides my comments. No, I don't think any bleed is needed.
@wawayltd I thank you very much for a quick answer and thank you for the great instruction in the video!!!
You're welcome 😎👍
Hi. great video! I have the same check code. but it occurs to me only when the air temperature drops below 10 degrees. the reason for this heater ?. heard that he is not alone can be ...my car is the same.
I know that in some countries, like US this heater unit was covered by extended warranty. In UK where I live it's not the case. I replaced it and it solved the problem.
In general - I hate this AdBlue system! The car is great, AdBlue sucks!
Thank you so much for such a helpful video!
Максим - you're very welcome, glad if it helps 😎👍
Found the tool name and the tightening torque for the ring: VW tool T50014, 80Nm
I find it difficult to get hold of these fancy VW tools. Don't know who sells them.
Hello there, I’d like to ask a question, I hope you don’t Mind. My sharan got a adblue error and engine won’t start after 600 miles. I topped up the adblue but still the warning sign is on. Is this related to P20EE code?
It's a common problem with VW. Quite often, it takes time for a car to "recognise" that AdBlue was topped up. My theory is that level sensor can be crystallised, and it takes time to dissolve. It can be a couple of days. Also, the manual says that after top-up, you should put ignition on for at least 30 seconds without starting the engine.
If none of that works, it should give you some fault code, why it's not happy, then it needs to be sorted. Please, don't use up all those remaining miles. Otherwise, it may be hard to start the car.
AdBlue is the right pain in the bottom!
great video. will help a lot of people.
major 007 Thanks :) I hope so..
as always ,all your videos well explained and helpful info:
Arian Taria Thank you Arian :)
Hello, please help me, after I change the reductant tank because of the heather, I had a new error code p203 b 00 reductant level sensor, I cleared it and after a few miles it comes back, thank you
I always thought that level sensor is inside that heater, but I'm not 100% sure, please check on forums or here:

Great video 😀when top up ad blue do you have to re set anything on the dashboard
After you top up AdBlue, put ignition for at least 30 seconds, but don't start the engine, and AdBlue sign will go away. That engine management light in this video, I deleted with the code reader, It could go away after some driving..
Thanks keep up the good work!!!
Hello, is it necessary to remove the tires to replace the Ad Blue heater? Can I get the tank and heater out with the wheels on? Thanks for the answer.
Greetings
Probably it is possible, but it would be a bit more tricky with less space. I think it is doable.
@@wawayltd Thank you for the answer. I have removed the tire. And than it works fine and the error is gone. Thank you for the video!!!!
You're welcome 👍
Nice video, I think VW increased the warranty period to 10 years on these heater units, not sure if it applied to yours
Thanks :) I bought new unit from dealership and asked about warranty or re-call on those - they said that never heard of it. Probably in the States..
Thank. Super, very good work
You're welcome :)
I have no lights on the dashboard but via VCDS I read:
P202A 00 [096] - Open Circuit
Intermittent - Not Confirmed - Tested Since Memory Clear
In your case, you had the check engine on the dashboard?
If in my case it says: "Not Confirmed" shall I wait till it confirms or shall I change it anyway?
Thank you for the videos!!!
I had "check engine" light coming up few seconds after every engine start. Yours is Intermittent, so probably is not a trouble yet. However, what I don't like about all this AdBlue system - is when you tank is getting low and you need a top-up, then it's difficult to get rid of that "top-up" light if you have fault in AdBlue system and it gives you annoying mileage countdown.
Not sure how serious is P202A. I kept clearing error and driving like that for like a year, before I found time, will and money to do so. In taxi miles 1 year = 60K miles. But I don't wait till AdBlue tank get empty, and that's another thing to get into for me eventually, because overfilling apparently is also not good...
I'll just buy Tesla ;)
@@wawayltd Eventually my intermitent 202A turned to a confirmed 202B. I did the job today, hopefully it will hold.
I have 2 questions though:
1-Did the check engine dissapeared right away? Mine did not. I did a short trip after that and it stayed. I cleared the code after the trip , now I am waiting to see if it holds.
2-The new heater, on the top, where the pump is connected, has two holes. One of them , the bigger one had a rubber ring pre-installed. The smaller one was empty in my case. But I found in the box also a small ring that fits there. Also the old heater cup had the small whole fitted with a small ring. I looked into your video but still not sure if you used the small rubber or not.
Also for people htat may be initereseted, the old heater had the resistance of under 15 Ohm whereas the new one has it around 2 ohm.
Anyway, before installing mine, I watched your video al least 4 times, and it helped a lot. Thank you!
Fantastic
Thanks Bob 😊
Hello, the engine light is still on after changing the ad blue heating sistem. I need to reset the error? Best regards and tnks 4 the videos.
What code does it give you?
Excellent vidéo, but did you know the résistance value of tank Heater ?
Thanks :) No, sorry, I don't know the resistance. Probably could've measure it - new heater vs old one.. But it's too late now.
WheelsAndMotors
Thanks, if somoene know the real résistance value of tank heater please Inform me. Thanks in advance.
Hi mate, my adblue bottle indicator lit up warning engine shut down in 600 mile. I filled with still 300 miles remaining but light did not go away. Engine has shut down will not start. VW technician said pump is faulty. if I replace the pump with a new one should the system reset automatically. Can Please advise on the correct procedure.
You shouldn't wait till mileage countdown goes all the way.
To be honest I have no idea what to do to reset it now, because I've never let that mileage run out.
In my experience all this AdBlue system is quite temperamental, and I haven't learned it properly myself yet.
You can replace pump, it's quite easy, although pump itself is quite expensive... but I'm not sure if it will automatically reset error. Perhaps you will need someone with clever computer.
Hi, does that new part also have the temp sensor in it??
I'm not sure where the AdBlue temperature sensor is. Currently, I don't have any documentation for Sharan, I don't even have that Sharan anymore.
If you are a DIY person, I can recommend VW website, where you can download well organised PDF documentation. Have a look at this:
erwin.volkswagen.de/erwin/showHome.do
@@wawayltd np mate.
Hi there
is there level sensor as well?
It must be somewhere, but by now, I'm not sure where it is, sorry. I don't have that car or documentation anymore..
Hi do you no where I can get one from? I’m in west London, I’ve been looking and can’t one used anywhere
Its for my van in the profile picture
I bought it from dealership. To my surprise it wasn't more expensive than anywhere in Internet.
Is there any difference between repair kit 7N0198970A and 7N0198970B? I couldn't quite make out what you said at 20:50 in the video.
Kind thanks.
They both fit, the one with the "B" is more recent version of the part.
@@wawayltd Thanks for your quick reply and a most helpful video.
Thanks mate for the great video, btw how much you charge for this job?? :D
Thanks :) Do you have same problem? Are you close to Bristol?
It's not actually that big job. I'm not sure if we both want to spend extra time for it.. Maybe your local mechanic can do it for cheaper?
Hi, many thanks for Video - managed to change the heater on my Sharan and clear the fault code. But I cant get the Adblue light to reset. Now the dashboard is telling me NO START in 250 Miles. Any idea how to reset this ?? I've tried ignition on for more than 30 Secs, tried disconnecting battery, tried driving for more than 2 miles but the light wont go out. PLEASE HELP !! ???
As much as I adore our cars, I hate this glitchy AdBlue system! The problem that you described is so common. And quite often even dealers not sure what to do. Don't want to put you off though... But please get it sorted as soon as you can, because when you run out of mileage count - car will not start.
If your AdBlue warning sign is in a shape of over-turned bottle, it's all good. But! If it;s a bottle with a spanner - that would mean that it thinks that there's an error in AdBlue system and filling up will not let it go.
I had it happen to me twice. First, I booked with dealership, and in the morning of booking date I discovered that error cleaned itself, so I cancelled.
Second time it came with a fault code saying something NOx sensor performance below threshold.. I found on forums and CZcams that cleaning AdBlue injector might help. It's quite easy to do, I did it, but didn't have time to video it.
Injector is located after DPF, near the place where exhaust is holding to subframe. Easy to reach - just raise the car (safely). It has same pipe connection as on AdBlue tank, electric connector and clamp with a little bolt that's holding it. Try not to drop any of adblue crystals inside exhaust. After I removed injector I cleaned it with water jet made by squishing plastic bottle with little hole in lid.
There are few videos on CZcams about adblue injector cleaning.
Than I took the car on motorway and the error cleared in about 10 miles..
Whether that will help you - I don't know, It's worth cleaning anyway because it's getting clogged up with that AdBlue salt/residue.
I'm still not sure if I solved the problem though, so I never have AdBlue low.
One day I'll get my head around it...
Sorry about load of text :)
Thank you for the swift reply.
The light is just the normal amber AdBlue top up light. BUT it will not reset. I do not have any fault codes listed and the engine MIL lamp has gone off since I changed the heater.
Im wondering if the level sensor is damaged - but I would have thought this would show a fault code. I have cleaned the injector ( it was spotless ), I took it for a drive on motorway ( 50 Miles roundtrip ). I drained the tank and refilled it with new Adblue - just in case. but still no reset. It is now at 150 Miles till No-Start.
Any other ideas of what I might try next ??
Any help would be gratefully appreciated.
I have another commenter to my another video with the same problem, here's what he said:
I've just managed to clear the error with a vagcom hex-can cable and VCDS software. The cable plugs in to the obd port and allows you to talk to the ECU properly. Expensive fix, but will no doubt be useful for other things down the line!
I did most of the procedure at the bottom of this page: malonetuning.com/how-reset-adblue-2011-vag-ecus
Using a cable from here:
store.ross-tech.com/shop/vchv2_ent/
It worked a charm, very chuffed. VCDS will basically let you do anything to the ECU that the garage can, static DPF regen, clear fault codes etc.
Hello ad blue 😂
thanhs for your video,
You're very welcome 😊👍
Hello, since a while I also have an issue with this error or alarm light due to Adblue. I see that the previous owner already repalced it couple of years ago and not sure why the issue appears again. It does not stop me for using it for now. I keep adding Adblue when I get the message. Is there another mean or alternative to the repare and replaceent you do to fix the issue? I still don't see anything from VW to take responsibility for this issue here in Europe. In the USA they replace it for free.
Hello, if you are talking about actual AdBlue heater, I don't know any alternative fix apart from replacing it. However since I have done it, the problem didn't come back, and I do a lot of miles.
The problem that I'm always scared of - when it runs low, gives countdown, you fill up, but countdown still there. Common issue. Currently I don't have time to look into it properly - I just keep it always full, fill up 10 litres every 4000 miles.
There are options to disable AdBlue, but as far as I know it's illegal.
@@wawayltd ok thank you. I'll keep surfing, maybe someone would have a fix. thank you
AD blue I have a problem with it; I can come to you to change it. Where do you live? Can I come to you? AD blue is not working.
Sorry Yusuf, I don't do repairs as business. Your local mechanic will make it better and cheaper.
