A4 b7 2.5tdi turbo (vacuum) fault
Hi all,
I have a Audi tdi 2.5 B7 A4 sline turbo actuator movement incorrect. Can anyone help? I have 2 fault codes p1654 (replaced coolant temp sensor-done) 01318 no communication injection pump. I have measured resistance of n75 around 17 ohms, 8.9 vdc supply to n75. As you can see the actuator stays at the stop screw. I have tested full movement of actuator with hand vacuum pump and egr valve. The vane arm springs back very quickly doing it manually so no sticky vanes
