What is a quick fix for an Audi TT cold start Idle?

Answer by  wally (39)

the problem probably is with the cold start valve... the cold valve shortens the time the engine takes to start.... replace it and the idling will be normal again..

If your car has trouble idling then your IAC valve may be dirty or damaged. Try cleaning it and see f it helps improve the idle.

There are a couple things you can do, you can try pumping on the gas to force more ignition in take, or you can replace the spark plug as this is probably the root cause of why your car is cold starting. You may even consider letting it sit and run a few minutes before you take it out.

It has something to do with your cold start valve. This feature shortens the time for the engine to start. It may needs to be cleaned cause the IAC valve can get dirty or damaged. You can see if cleaning it will help before you buy another part. All what I said do for the above should resolve the issue.
