    B7 S4 Red Oil Pressure Light

    Guest-only advertisement. Register or Log In now!
    Oil was changed about 1K miles ago. No issues at all , but on the way to work Red Oil Pressure light comes on! Have checked the oil and oil level is right where it should/needs to be. I've been reading and a lot of people are telling me the sensor on the back of the oil filter most likely has gone bad (sounds common). I've read it's a simple swap and I'm comfortable working on my car, but I'm just looking for some clarification to know exactly what Sensor I need to purchase online to put in myself? Anyone familiar?

    DO NOT DRIVE THE CAR until you solve the light...

    Buddy had a oil pressure light come on and he checked the oil and thought nothing of it since it was full, this went on for 3 days and he thought it was a simple malfunctioning sensor, until finally on that third day he blew the motor because the oil pump failed and was not pumping oil.

    I know it's a little cheaper but I'm looking to do it sooner than later, the local autozone has one for about 10/15... Does this match what you were referring to? ( http://m.autozone.com/external-engin...8537?location= )

    Hmm... Definitely don't want that... Is there a way to "check" the pump myself or do I need to get a diagnostic for that ? (I plan on changing the sensor tomorrow) but don't want to overlook anything

    is the 1 hour diag at a shop worht it here , yes it is. these are not cheap engines and cant be found easily. you can always buy the oil pressure tester and fitting and do it your self but i would check your oil pressure and not just throw parts at it .
    get one of these

    Hate to sound completely clueless lol, but I just want to make sure it's done properly.... When I look up B7 S4 oil pumps I found an Oil Check Valve kits, but I feel like that's not the same thing. Where do you guys typically go for parts or to find the right part?
