I've got a rough idle on my A3 2.0TDI BKD.
I've turned the idle RPM down to 800 but didn't help much.
When starting up, sometimes it's a little rough and perhaps even getting a little worse in fairness.
I've done a VCDS scan with no issues.
The only thing I think it could be is dodgy cam timing (seem to read a lot on this).
I had the cambelt changed by Awesome last November, and have had a judder ever since but it's never overly concerned me. I'm not saying dodgy job by Awesome because I'd only had the car about 2 weeks before the change, so it could just be I didn't notice before?
What I want to do, is there any settings I can change in VCDS to help things along? I'm taking it any physical changes to the cam timing would be risky and shouldn't really be attempted by me?
