Hi, I have had the dreaded 'No restart in 650 miles' due to an adblue issue. We know it's electrical and I assume it will mean a new module. As with many, things are tight so thinking of getting a used part. The code is 4M0907355. When i have searched however, there seems to be a letter at the end, either a D or E, and i think i spotted a G. Does anyone know what that means. I have a 2016 Audi A4 Sline Diesel.
Also, any ideas how much it would cost to fit the part when i have purchased it?
Thanks Dan
