Greetings all,

Since 10 months I have an Audi R8 V8 from 2008. And since the beginning I have a small issue.

The problem is that if the engine is warm and idling for a few minutes (stoplight) it is smoking a lot when giving gas.

This only happens after idling on not with a cold start. Only when the engine is warm. The R8 does it already for 4000 miles and it is not getting worse.

Is a carbon clean the way to go? It has 100000 miles on the clock.
