Re: setting idle speed on a 2001 vw beetle 2.0-
The engine doesn't have a mechanical idle speed adjustment - VW/Audi have a software called VagCom (the diagnostic software they use) that is used to adjust the idle - it's completely computer-controlled. You have to change the idle speed using the software.
I have changed the idle speed on other cars by adjusting the throttle position sensor but it may also change your shift points. Try small adjustments.
