[h=2]A4 170 TDi lumpy cold irratic idle[/h]As the title states; I've just bought the car, had a full service and cambelt change by a local knowledgable VW Indy. Ran the car at the weekend and it's been fine. I had Audi do the injector recall yesterday. The car now has a very lumpy idle until it gets a bit warm. Any ideas?
