Hi there, did an oil change and also changed dash loom for a new one but now the oil light is buzzing but only when revving, has anyone has had this problem?
-
is the dash loom from the same age car as yours? The wiring changed later on and there's only one oil pressure sensor on later ones.
-
dash loom is from a 1994 polo on a k reg, my polo is a 1991 on a h
-
yes then the loom will be from one with a single pressure sensor. You'll need to clocks to match really. Or run your own wire from the 2nd sensor to the correct pin on the back of the clocks.
-
excellent cheers for your help, ill run a wire from the second sensor to the clocks :)
-
I think there's a pin-out diagram for the clocks connector in the electronics FAQ section somewhere which will tell you which pin to use.
-
got it, pin 24......cheers for putting that up, a great help
-
hayesey, which switch do i run the wire from? ones a high pressure and one is low?
-
not sure off the top of my head. Have you got a haynes manual there? See which sensor goes to which pin on the back of the clocks. The wires from the sensors go directly into the clocks.
-
My g40 dose that when u rev it up the light and buzzer gose on and stays on, loom is original :/
-
Checked the sensors to see if they're working? From memory one is for <2.5k RPM and the other for >2.5k RPM, although that may be mk2 golf.
Someone had that on here not long ago and turned out to be a dodgy set of clocks. Everything fails sometime!
