I have a 2002 Audi S4 (2.7 V6 twin turbo with automatic transmission). I got a code P2101 (TAC Motor CKT Range/Performance). What does that mean? Please help!

 

The problem was fixed.

 

what was the problem please?

 

youre having an issue with the throttle body. it may be broken or just might need an alignment. there is a motor in the throttle body that operates a flap to the intake manifold. the motor may be acting up.

 

thanx for the reply bro.

 

do you think its the tps or the throttle body its self?

 

could be either. pull the sensor and see if anything changes. if the problem continues thats the problem. try the throttle alignment. just switch your car to on position for a minute then start the engine.

sorry for the lag in response.
