VW idle speed stabilizer. Idle speed is controlled by the idle speed stabilizer valve, and electronically control rotary valve which is really just a fancy bypass of the throttle body. When the fuel injection "brain" receives a signal that the idle is too high or too low, it makes fine adjustments using the idle speed stabilizer. Over time, the valve gums up, causing it to respond too slowly which causes the brain to "over shoot" the adjustment. This makes the idle hunt up and down. The valve can also stick, causing a consistently low or high idle. If you're having idle problems, there's a good chance it's your idle speed stabilizer. It's an easy fix - remove two hoses, one bracket and one electrical plug and it's out. An easy 15 minute job!
