So if you are looking at your block with your knees on the front bumper. Yellow is the left sensor and blue the right one

this is what mine are like:




blue wire to blue sensor,

yellow wire to black one.

You need to check the pressure ratings on the sensors, they could be wrong.

Use these part numbers? And these should be the pressures.

028919081D
oil pressure switch
0,25BAR M10X1 1 pin blue

068919081
oil pressure switch
1,4BAR M10X1 1 pin black

I had no end of issues with my G40 and the oil pressure buzzer thing.
Ended up hooking up an Audi pressure sender to a pressure gauge and earthing the yellow wire to the head.

Is there not something about early cars with late clocks or the other way around which can cause the buzzer to go off no matter what?

Thanks for that kwijibo...but i havent heard of that b4 about the late clocks...ill ask around.....

Thanks pal....

Had a look at my oil pressure senders today...the one connected to the blue wire is a dark brown colour...part number 056919081c and has 0.15 to 0.45 bar stamped on it...it a genuine vw one...the black one i replaced that joins to the yellow wire has 1.2 to 1.6 bar stamped on it....

Has for the clock idea....its on a j 1991....so im assuming the clock should be fine either way.
