Hi,
I am getting Rough idle an erratic idle on startup but this doesn’t happen every time. I have taken it to an Audi diagnostic specialist who could find nothing wrong and said it could be something to do with the egr valves and it trying to fool the emissions. It’s really annoying but other than that the car runs lovely! Any advice would be great. Thanks
