Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
I need to know the color of the light
yellow/amber or red?
Red Oil pressure light , I am going to change the sensor just trying to figure out where it is located and how to change it, strong believer in change the cheapest part first
Actually says oil pressure
ok, got it. Just wanted to make sure that we weren't dealing with a level sender
The sensor is screwed into the back of the filter housing at the top of the enging
Is there anyplace that I can get a pic or diagram that I can show my mechanic
Best to do a physical pressure test, in my opinion though
using a mechanical gauge
Pressure should be at least 2 bar at 2k rpm, with engine oil at operating temp (90c +)
Should an Infiniti shop be able to pressure test an Audi , I would think so but never know if there is any special equipment needed
hard to say. All I work on is Euro, so not sure if they will have the proper stuff. In most cases, a good oil pressure test gauge will have a multitude of fittings
OK , will send this to my mechanic and should hopefully answer his questions
