Can't find out which part this is!

Asked by Jan 26, 2012 at 01:39 PM about the Audi 100

Question type: Maintenance & Repair

I have a 1994 Audi 100 that is leaking at the bottom of the expansion tank. I have looked everywhere trying to find out what part it is and if I can replace it myself, but I can't find any schematics for it. It is not from the hose but from the electrical looking plug. Can you please help me figure out which part this is?

1 Answer


That will be your coolant level sensor. It can not be removed from the expansion tank, they are replaced as a complete unit.
