Hello,

I am a new member so I hope this all goes through OK

I have a 2007 A6 2.7 tdi avant. From time to time the oil pressure warning light comes on when I start the engine. After a few moments it goes out and the car runs normally, the oil level is correct. I am just changing the oil and filter and I would like to change the oil pressure switch but - not being a modern mechanic - I have no idea where the switch is located.

Any pointers would be much appriciated.

Steve
