I was wondering if anyone could help me locate the oil pressure sender. Does anyone know where it sits on a Audi A6 2.7T? Do I have to drain the oil when I change it or is that not necessary? I have attached an image of the part that I need to replace.

Thanks!

 

i was just under my audi giving it a good look over while i was draining my oil.. there is a sensor right on the bottom of the oil pan.. no wether that is a temp or pressure or low oil sensor.. im not sure, but it might be a good place to start

 

on top of the oil filter bracket. there should be two pressure switches just make sure to read on the side of it what the Bar rating is...don't mix up the two. Just read them and you'll be fine. No need to drain the oil there won't be much that comes out just have a rag handy for the little bit that does.

If you have any questions don't hesitate to ask.
