Hey Guys,

I just picked up a A4 3.2FSi with 2 cylinders shot on the engine. I have recently rebuilt the engine. The car has started up but I have some codes being thrown up -

1). U1113 - Function limitation due to received malfunction value
2). P0123 - Throttle Pos Sensor A - High input
3). P1545 - Throttle Valve control system Malfunction

The car is idling very rough and also not revving beyond 1200rpm. I have checked the wiring and seems to be all good. Could this be a bad throttle body issue or is there a possibility of Valve timing being off ? Need urgent help please.

Thanks and Regards

Sparky
