Recently got an A3 1.6 sport 2002. When i bought it i noticed there was a slight uneven tickover, i didnt think anything of it, just thought it needed a good service.
However I have now noticed that when the car gets warm and i pull up to a set of traffic lights for instance, the revs go up and down between 1000 and 2000 for about five seconds before they settle down.
I went to a local audi specialist yesterday and he said that because the throttle is electric instead of cable then the throttle body gets dirty and it just needs a clean. Just wonderin if anyone could give me some advice on this.
