Electrical problem
2001 Audi A4 4 cyl Four Wheel Drive Automatic 131000 miles

i have changed everything possible in my car including the oil pump and oil pressure switch four times. The problem is that the red oil light shows up on the dash. The engine runs great with no problems, and there is no noise, again the light keeps coming on though. Do you know what it could be?

Hi there,

This will be an earth type switch, I would be thinking that the sender wire is grounded causing the light to come on, that is if the pressure is correct did you test it with a mechanical gauge?
