Flashing OIL light

[heinz]

The oil light on my 2E engine keeps flashing  only does it when it revs over 2000 wont stop flashing until I turn the engine off
  There are no fault codes, was running vagcom when oil light was flashing
   Oil pressure is very good  using a vdo pressure gauge showing 4 bar
idle is a little high and a little rough.
 any help would be great please

Either the sensor is boogared, or the pickup in the sump is getting clogged up, which would involve, dropping the sump off and giving it a clean out, oh and cleaning up the sump to get all of the sh!t out of it.

I have 4 bar of pressure when the oil light is flashing taken from the sender on top of the oil filter? so why is the light flashing when I have pressure

Knackered sender unit....or loose wires.I had this on a mk3 I fixed about 4 week's ago and was informed by my friendly vw specialist that it had more than 1 sender??

Will have a play with the sensors   haynes book of lies says the oil sender on top of thee filter housing only comes into operation over 2000 rmp  so will try that one first.

 there is a sender on the side of the cylnder head and one on top of the oil filter housing.

Think I have fixed it the VDO sender shows a couple of ohms to earth compared to the oem sender that is open circuit to earth

the top sender shows .7 ohms to earth
and the oem sender is open circuit to earth   can some one check these readings on there senders please?
