I have a 2004 A4 and I am facing this problem:
Sometimes when you press the accelerator, neither the car moves forward
or the rpms increase. Is it something related to electronic throttle-body? I took it to the dealership since it is still under warrenty but they told me nothing is wrong with it. Please Advice

Thanks

 

Theres nothing else i can think of that would have the same effects as that but a bad DBW system. Did they just check the TB or did they atleast check the peddle?

 

Yeah, don't think anything else would cause that - some type of disconnect between pedal and TB for sure.

 

I am not sure what they exactly did. But they told me if it occurs again bring it back and we will let someone drive around with u. The thing is it happens randomly and it might not occur during the test drive.

 

It seems like that is always the case and the techs just look at you like ur on crack because they don't believe you
