If your vehicle is an 86 or newer, there is an idle stabilizer valve mounted on top of the engine and an Idle speed control box located forward of the right hand brakelight( pull the light to get to it.) These two work together to prevent engine stall by: 1) Kicking up idle engine idle rpm when the AC kicks in. 2) Kicking the idle speed RPM's up when the powere steering is moved to the physical limits of rotation, 3) Kicing up the idle rpm on a cold start. Often the one unit or the other will give trouble. If one is replaced, the other needs to be replaced also. The electronics of the Electronic Idle Control Box in front of the right taillight, will often burn a resistor, and then quit. This is a common fault. These units are expensive and VW has never supplied a decent replacement.
