I've a 2003 A4 2.0 that had the restrictive acceleration and would not pass 3000 rpm without juddering.

Auto electrician said it was the throttle body so had that replaced with the Lambda & Crank Sensor, everything fine for 2 weeks but now it's back.

Any ideas I can talk to the garage about?

Thanks

 

Coil packs or misfiring on last cylinders? As it is happening when there is stress on all cylinders...

 

what codes do you have?? Many things can cause limp mode! What was the code/problem initially that made you replace the TB and senors?

(2003 2.0??)
