Our 1995 E320 is dipping down to zero Bars when its in drive when i accelerate it shoots up to 3 immediately , but here is the strange thing, i open the oil filler cap and is saw oil shooting at the cam shaft means that i still have oil pressure when the gauge reads at 0, It was all fine until today... What could be wrong, oil sensor issues, oh when its cold oil temp goes up to 3 bars(Obviously the oil is thicker hence higher oil pressure)
