I have an a3 2.0 TDI (2004) BKD.
I still have my rough idle that only occurs while the car is heating up. Final straw so i sent it into Audi yesterday for 3 hours. They checked everything and literally nothing is showing a fault- nothing! So my car is fine but yet idles like cr*p! They say the only thing left that it could be is an injector. Ive been reading the other threads and it seems like an easy solution (before thinking about changing the injectors) for this could be to raise the idle rpm slighty (by 100 or 200).
So for this i need Vagcom/VCDS or someone with it. I really cant afford to be spending much more money on this anymore so was thinking of trying it myself. Can anyone help me with what i need to buy (ie-software/cable). Is it expensive or is there a cheap e-bay copy?
Any help would be much appreciated!!
