Hi all - first post.....
I have a 2015 A6 (Ultra engine etc.) - wife phoned me the other week while I was away from home with work telling me that the Adblue needed filling (she had the information message on the dashboard). I asked my 18yo son to fill the Adblue tank as I usually do it myself, don't usually have any issues with the fill. Famous last words.
After my son had filled the Adblue tank and had started the car to check that the information message had been cleared, they were presented with the Adblue System Fault message and amber/yellow warning triangle on the dashboard. I'm now back home trying to diagnose the issue.
My working hypothesis is that the tank may have been over-filled and that the internal Adblue sensor can't detect the amount of fluid in the tank.
I ran a scan using VCDS the other day, output below - I've received the P204F 00 [101] - Reductant System Performance Bank 1 fault code.
I'm thinking that the next step is to
1. Reset of SCR tank level detection and then
2. Reset the SCR lock.
Anything else that the forum would recommend?
Cheers, Nick.
ps. Yup, I have a few other faults that I've cleared after this scan (with the exception of the HVAC fault).
