I am having trouble finding the temperature sensor. The haynes manual does not show me where it is. From the internet it says it probably as small green thing that plugs into the left side of the cylinder head but I cant find it. My car is an A3 1.6 Sport 1998 model, engine code AKL. Does anyone have a picture they can send me of the engine with a big red arrow pointing to the sensor as this is driving me mad.
