P1544

P1545

Throttle Pos.Contr Malfunction

 

 

I would suggest you investing in a VAG-COM (can be purchased from www.ross-tech.com )

 

I would recomend trying to clear the faults and setting the basic setting for the throttle body and see if the faults go away and the basic setting, sets.

 

Those faults can cause the vehicle to stall out, if the throttle body will not respond the engine will not run very good and stall out.
