Hello! Our beloved A4 TDI 2015 reminded of her age and is displaying the not-so-pleasant adblue error with no restart in 1000km. Had the fault codes read and it's pointing to a faulting control board. I took a look under the car to try find the board, and also looked everywhere online to find out where the board module is located but simply haven't been able to find out about it. Apparently it's a different to B9. Anyone able to point me where to look?
