A6 2.0 TDI Mulittronic Poor idling

[SMBrown]

I bought an eight month old A6 4 weeks ago, but from day 1 it had a poor idling problem - like it was misfiring on one cylinder. It does this until it's warm and only when stationary - occasionaly it splutters so much that it stalls! . Beachwood Audi tried to fix it but couldn't. They contacted Audi Germany who siad it knew about the problem and were working on a fix, until then I had to put up with it - they showed me the e-mail. Has anyone else had a similar problem and if so has it been fixed?

I was waiting for this post.I am dealing with four 2006/07 2.0 sline multitronic irratic idle at junctions and misfire.They all seem to be 140bhp and the same software versions,there are a number of software up dates that cover this issue but none work,i have found the egr values are incorrect and can only be altered by blanking the egr port off,however this causes the emmision light to come on.Fear not you are not on your own and two vehicle have been tested at audi uk and the results have been sent to the factory for some urgent feed back to repair.I feel your irratation as i require a fix also for my customers who so far have accepted the issue and await a repair,i have seen the fault on road test for my self and its not good,i will say your deaker is correct and they can do nothing until a repair(software up date) is released.Regards Jon

Thank's Jon. You've put my mind at ease. I was wondering whether I'd been given the right info as I couldn't see any threads that covered this problem and my garage acted as if it was the first car with this prob they'd seen. It's true what they say - "Misery likes company" - I feel better knowing that I'm not alone. Again thank's. Stuart

Audi have at last found a upgrade that works. No more lumpy idling.
