I recently bought a 1996 audi a4 2.8 v6 quattro. And the guy I bought it from said that I need to replace the oil sensor. Where is the oil sensor located and what is the process of rplacing it? Thanks for any replies. You inputs will be much appreciated

 

There are two - the oil level sensor is in the bottom of the oil pan and I believe the oil pressure sensor is on the oil cooler (which is where the oil filter screws on).

 

I believe its the oil pressure sensor... I think the oil filter is behind the radiator.. Will I need to remove the radiator or can I do it an easier way??
