Oil pressure Q4
I've been wonderng for long time, whitout asking around (?), what might cause extra high oil pressure?
I read in the repair manual for the Q4 that the oil pressure should be 4 bar at 3000 rpm. What is strange is that my pressure is always at 6-6.5 bar and someties close to 7 bar even when the engine is really warm.
It is not due to too high oil level, that is checked. And it has been that high since the car was new. Bt it was not until I got the repair manual I realised it was too high. It might be the sensor or soething like that but I have had problems with leaking cam-shaft cover for long time. I replaced the gasket, but it didn't help much.
