Hi all, more problems, oil light is coming on at random times and random revs, I have put a pressure gauge on it and when hot at idle it reads 25 psi and at 2000 rpm it reads 75 psi book says hot at 2000 rpm it must be at least 2 bar ( 30 psi ) so I think its not actually an oil pressure problem only a switch problem. what I do not understand is why is there 2 pressure switches one on top and the other underneath the filter housing what is the reason for 2, can anyone explain please? engine is 2.0ltr 8 valve ABK Audi
