Audi A4 Ultra 2.0 TDi (2015) Adblue Fault, No Fault Codes 😳

[@sebczajna700]

Can you explain to me what you did? did you clean the adblu injector?

Modern day Shite Sandy , these systems are so complicated its untrue , we need so many scan tools nowadays to change a light bulb 😂😂😂😂, the jobs getting crazy , VCDS is a must nowadays for VW range , and idis both readily available for not big dollars , job done though , thats all that matters 👍

Hey, sandy nice to see you work on Audis 😉 you know if anyone have cleared the codes before you got it? I have seen it clear but the warning is left and then you have no idea what to look for. I have only used odis when resetting this and it requires a drive to reset the warning, so maybe your scan tool started the test. Cheers

Some remaps include DTC disablement, that could be the reason.

I had some experiences of AdBlue system. In case of AdBlue system, there's possibility that no fault code but the warning lamp on. It's because someone had only cleared the fault code before the system went back to normal. And I think your long drive is one of good solution to turn off the warning lamp. Some of AdBlue fault codes requires certain amount of AdBlue injection to go back to normal. For example, P20F4, P20F5, P20EE, etc. (The detail of required condition is probably different depending on car manufacturer)

Here is what I believe happened. I have the same car with the same engine and the same problem. I think the error code was deleted before they brought the car in. They thought just by deleting the error code the dash will also clear but this is not how it goes with this error. The actual error was 28653 - Reductant System Performance Bank 1 P204F 00 [101] - Malfunction. This is due to a failed readiness test. You should have checked that. A couple of ways to approach this but the best is to reset the readiness and do all the tests. Watch this: kzbin.info/www/bejne/mJKulax7pLyUes0

I just found out that I have a new engine software - mine is 8510 now we have 9550. Hope this is exactly for this issue. Tomorrow fingers crossed I will be updating.

Thankfully I disabled my AdBlue, it gave so many issues

[@blowawaytheclouds1]

How did you get it disabled?

[@Habs1967]

@@blowawaytheclouds1 services in my country that disable AdBlue, it was either that for 300 euros or having to pay 1500 euros to fix the damn thing...
