The oil pressure (red) light comes on just before it hits 2000 rpm on my 1.4 beetle. I've replaced the sensor and this hasn't made any difference, i'm guessing I need to drop the sump and replace/ clean the oil pickup. Any advice on getting access to the oil pickup ?
well I dropped the sump and cleaned the oil pickup but I'm still getting a pressure light on
weirdly if I disconnect the sensor I still get the light come on at 2000 rpm.
I plugged a manual oil pressure gauge into the sensor hole and the pressure is 20psi on tickover and 50-60 psi at 3000 rpm so all seems ok there.
I just don't understand how I can be getting a oil pressure warning light come on at 2000 rpm when there is no sensor connected. If I earth the sensor wire out the light does not come on as you would expect.
