Oil Pressure Warning - MK1 1800 GTI

Got the old age problem of the oil pressure light coming on with the annoying buzzer!

I believe this could be one of two things :

1) Oil pressure sensor

2) Electrics on dash circuit board

Anything else?

Cheers

Low oil pressure :dontknow:

Sorry couldn't resist.

PS Do know 100% that the oil pressure is OK?

I dont know that the oil pressure is 100% but wouldnt the warning always be on instead of just once in a blue moon and flicking lights on and off stops it ???

Possible if there?s some debris blocking something up but normally you would expect low pressure to show up on a hot engine when the oil is thin and yes to do it all the time consistently.

I have a VDO gauge showing good pressure and mine flashes occasionally, usually when its been parked in bright sunshine all day and the dash/instruments are baking hot. Very occasionally the buzzer will join the party as well. 9 times out of 10 a rap on the instrument cluster with knuckles cures it. Been thinking about resoldering all the joints?

Search for the many threads about this. In theory you can?t trick it by disconnecting senders as there are two, one open and then closed and the other the closed then open. The logic in the cluster also takes into account rpm (2000). This can be fooled by removing the appropriate wire form the coil but then your rev counter will also stop working.

Check all your earths if turning your lights on effects it.

I has this a few weeks back and it turned out to be a loose crimp connection on the oil filter housing sender,

cheers, Derek

my fault turned out to be a didgy oil filter!! spent many hours trying to solve that one
