Injector fan working or not? 87 5kcstq

[David]

At least on my CGT (NG), the after-run sensor is attached to a clip that is connected to the valve cover at the rear of the engine on the drivers side. heat it up with a match or lighter. There are 3 heat ranges for this sensor avalable from Audi IIRC...
