Red coolant light flashing volkswagen4/28/2024 ![]() So I'm guessing (assuming that I got a good expansion tank ), that I'm looking at either a fault within the instrument cluster or a wiring fault.ġ) Is the circuitry within the dash replaceable ( e.g. Well I replaced the expansion tank today and the coolant level light is still flashing after the ignition is on or engine has been running for a few minutes. ![]() I guess that I will have to change the expansion chamber as it looks as if the sensor is built into it.Īny pointers would be greatly appreciated. I can't find any details anywhere to tell me what the resistance should be.Ĭan anybody tell me, firstly if my fault diagnosis is right and what resistance I should be looking at ? I put a multimeter across the terminals and it is indicating open circuit with the expansion chamber correctly filled. I suspect it is the level sensor in the expansion chamber. There appears to be no problems with the head gasket because there are no bubbles coming into the expansion tank when reving the engine.Īlso I have put Vagcom on the car and there are no faults listed. When the car warms up the thermostat does operate because the top hose to the radiator does warm up. I have looked at the coolant level and it is correctly filled in the expansion chamber. The coolant temperature does warm up after a few minutes to approx 90 degrees on the guage and it does not overheat. The seller did warn me that the red coolant light was continually flashing, immediately after start up with the engine cold and at other times intermittently. I have just bought a 2002 1.0 ltr Polo for my daughter as a car to learn to drive in. This is my first visit to the Polo forum.
