2.6 V6 Low Oil Pressure @ Low Revs?
Just after a bit of information or/& help.
I have just invested in an Audi 80 2.6E V6 and have noticed that when up to temperature, when at tick-over, the oil light comes on and the gauge in the centre dash reads almost zero. The light goes out with slightly more revs, taking tick-over from 750 to 1000 RPM, and the needle in the gauge picks up to just under 1 bar. When driving, the oil pressure light never comes on, but the gauge only reads not much more than 2 bar with normal driving.
Any offers on whether it's a low tick-over related problem, grade of oil, oil pump, faulty sender unit? Or infact it's a common problem.
Car has just done 107k miles on a 1995 and I had it serviced with its MOT at an independant VW Audi specialist.
