Have a problem with my Audi. All was fine till yest today when i start the ignition i get the EPC/Check engine light on and when i push the acceleration it doesnt work. Its moving but at its own pace.
Any idea wht might be wrong.
Thx in advance.

 

could be the throttle positioning sensor.

can u describe the problem better?

 

what was the code from the check engine light? It could possible be a vacuum leak.

 

Check t h i s out.

Had no idea what EPC means; learn something new every day.

 

Well.. let me see if i can describe it any better. Well the car starts but i see both the EPC/Check engine lights on.
Now when i put in drive and hit the accelerator.. duh it doesnt get the acceleration but its moving at its own slow pace. Hope its not
the transmission. Geez ! Any help is appreciated.
how do i check the code from check engine light ? have an appt with the dealer on Mon.

 

No sense in driving the vehicle if it's like that but if the CEL is blinking your not supposed to.

You need to pull the codes with a VagCom. Generic scanners can't read all of the codes. Once you have the codes you can post then and we can look them up for you in the Bentley manual.

 

when its moving at its own pace is the engine revving and the car is not moving as expected or do you mean that you are pressing the accelerator but the engine doesn't rev as expected thus the car doesn't move as expected?

 

yes the engine doesnt rev as expected and the car doesn't get accelerated. For the codes do i need to take it to a dealer or can i do it myself. if so how ?

 

Have you checked if your throttle (acceleration) cable is still attached on the throttle body?

It sounds to me that you cannot get any revving up, no matter how hard you press the acceleration pedal. On the other hand, when you engage a "drive" gear, the car just goes at its idle pace.
Like someone else said, probably the throttle position sensor is the culprit (that would be the electric side of it - tripping the EPC light), but then again it sounds to me like your cable doesn't open the butterfly flap (from what you describe)

 

If you can get the car to an Autozone or equivalent, they read codes for free. In your condition, I'd call ahead and confirm.
