Oil Leak AAN Engine - 94 S4

[Steve Mills]

The single wire sensor is the oil pressure switch and is most likely the source of the leak- they are known to fail either slowly or catastrophically. Dona search on the RS2/UrS4/S6 forum on quattroworld using my screen name (boxflares) and there is a post on this with the correct part number.

There is a large sending unit on the side of the block just above the rear of the A/C compressor; I'm assuming that this is the oil pressure sending unit. Above that is another sensor with a single wire running to it; It appears that this sensor is the source of the leak. If anyone can identify the sensor so that I can get a new one it would be greatly appreciated.
