Goose2017

Having ordered new tank and pump from Audi for the Audi specialist to fit, only one component turned up so had to abandon the repair until after holiday and planned to hire a car for the trip. Went to pick the car up and the warning had gone. Garage said they had not reset anything. I am thinking the diagnostics test must have in some way reset the computer but what do I know. Have driven the can with no problems for about 6000 miles. Now asking for Adblue again and have same problem with light not moving from 650 miles no restart. Any ideas?

Hi Mark, I also have an A4 Allroad 2017 and had pretty much exacty the same problem - car asked for adblue, filled it up and message turned to adblue fault 650 miles no start. It has in the past taken a day or two to go out, but now driven 400 miles and still says 650 no start. Taken to an Audi speacialist (not a dealer as two in London told me to take a hike for a fews weeks and then they could fit me in to do a diagnostic). Faults are Lost communication with reductant control module. and Reductant pressure to low. To fix I need a new Adblue controller £690+VAT and a new pump / tank £941 + VAT total with labour £2,665, so not quite as horrendous, but using a specialist not a main dealer. Having discussed with some Audi mechanics, this seems to be a very common problem which Audi are not being as open about as they might be....
