Hi everyone, I’m a mechanic based in Glasgow Scotland, a customer brought in a 2010 2.0 tdi Audi A4 (engine code CAGA) after diagnosing the non start condition I have found that the hpfp was at fault (cam follower worn inside) after replacing all 4 injectors filter,lpfp and hpfp with a Bosch unit the car run fine for 30 minutes and then cut out, I’m now not getting any pressure after the pump, only from the electric fuel pump to the hpfp supply, has anyone ever experience something like this and could shed some light?
