Unknown fault code and max 4000 rpm

[GC001]

Twice now I have had the EPC light illuminate and max 4000 rpm come up on the S4.

It clears when you restart the car, and each time i've scanned it it says its an unknown fault code. It seemed to at both times come on when giving the car a bit of stick and when it changed at max rpms at the redline.

Google says oil pressure switch which I guess is on the sump.

Makes sense that detected low oil pressure would cause limp mode. Could be a faulty switch/sensor but if it's genuine low oil pressure then you'll want to get that sorted asap.

What are you scanning it with ?. Generic fault code readers do not always report correct information. I would suspect the fault is more related to some kind of boost / temperature issue which is causing limp mode.

^ is it missing could be coils?
