Can anyone help? I have a 1990 Merc 190e auto which always runs beautifully. However, the reading on the oil pressure gauge occasionally 'bounces' around and will sometimes show no reading at all. HOWEVER....when I press the trip meter reset button a couple of times (I did this originally to see how far I was driving with 'low' pressure), the gauge suddenly springs to life and reads a very healthy
3.0 dropping to around 2.5 when idling. Sounds like a wiring problem rather than sender unit, but has anyone else ever experienced this? If so, what is the solution?- posted
