Hi Guys,

When i am starting my Audi A6 and trying to raise ( accelerate ) initially it is giving jerks ( jumping) .. this happens mostly when start first time in the morning. But after i drew for a mile, it runs smoothly. Please let me know what would be the reason which part is not working properly?

Thanks in Advance...

Kittu.

 

Are you literally starting the car and then hitting the accelerator while the engine is still cold?

I believe if your cats aren't yet warm this could cause a somewhat rough-riding sensation until the cats warm up. I think this is what your secondary air pump is for, though.
