I have the dreaded fuel cut issue in my audi A4. I have now had the High pressure fuel pump, camshaft, camshaft bucket follower and pressure sensor on high pressure fuel pump changed but the problem remains. I have not cleared the fault of the ECU, could the car still be going to limp because I have not cleared the fault ? I had a look on ETOS on the only related parts left now are a thrust sensor and pressure valve. the fault code comes up with a mech fault with the high pressure pump. Any help would be great !
