Hi,
My son owns a 1993, 1043cc Polo. Today, the oil and temperature warning lights are remaining on but the buzzer does not activate. The engine is not running hot and seems to be running fine. I have tested the electric fan and it works okay. I have checked and cleaned the various earth points around the engine compartment. The workshop manual suggests the usual things but these all seem okay. I am wondering whether this could be an earth fault, as the sensors appear to link back to some sort of control module which I assume is located behind the speedo head but U cannot find where this module earths. I am presuming that if that module has failed, the buzzer would sound also?
I would welcome any suggestions as to the likely cause and how to remedy?
Thanks
Oil Warning and Temperature Warning Lights
On the head of the engine there ahould be two wire going to oil pressure switches(one for low pressure and one for high pressure) there might only be one on your car...
undo them and make sure the hole isnt blocked (i used a copper wire poked through to clean them) then try again. if the light is still on then the sensor could be faulty..
