Hello I’m Darren and I’m new to the site.
i have just purchased a used Audi avant Quattro 3.0 tdi, I had tested the car as best that can be tested and the previous owner was a straight up guy so no problems there. On my second day of owning my new chariot it just stumbled and cut out, I tried a restart a few times and it just ran rough for 20 seconds and then died. The AA guy diagnosed it as a crank sensor, so we towed it back to the garage and I changed the sensor, still no difference at all and after a while it flagged up again. After using the vagcom software it showed as erratic fuel pressure?
Im lost on this one and could desperately do with some ideas please.
cheers
