Hi folks,

I’ve got a S3 8v and it’s currently got an issue on cold starts. When I start my car the revs increase to around 2000 rpm then drop back down too 1200rpm then increases back up. Once the cars done it’s cold start (around a minute) it’s fine idles normal.

I’ve check coolant and oil levels all fine no leaks that I can see. Before The car on cold starts always revs to around 1500rpm and stayed then after drops back down to normal rpm around 1100rpm.

Any ideas what this could be? My cars totally stock, just had full service recently and always ran on Tesco 99 momentum.

Thanks.
