Having issues with 2006 a3 2.0 TFSI (BWA engine) where anything over 4k rpm the need jumps all over place with "EPC" flashing and have loss of power.
If I come off throttle, engine returns to normal untill I go over 4k again. If I force this the car will eventunually go in to a sort of soft limp mode were I can go over 4K rpm but with servere loss of power/ no turbo.
Starts fine everytime.
Checked all the normal plug & coils etc. ran vagcom and I am getting a P0321 code (Engine Speed Sensor (G28): Implausible Signal) which leads me to think it may be this.
Can anyone point me in the direction of its location as I cant seem to find it via the search bar/ google
