Hi guys,
This error came up while I was driving home from work a few days ago. It basically said that there was a system fault with the AdBlue and that I had 650 miles before no restart. I wasn't that far from home so I managed to get home without a problem. Then, when I started the car the next day, the error didn't come back up. The error came on again when I was driving later on. I read online that I should top the AdBlue to the brim and see if the error comes back on. So I filled the tank up and the error is still present. After doing a scan the faults below have been identified.
I have read on other posts that a replacement AdBlue pump fixes the issue. I was just hoping to get some clarification before going down that road.
My car is a 2014 Audi A6 C7 2.0 Ultra with 160+k miles.
Any help would be much appreciated.
