Club 80-90 Forums

Hi everyone, If i may pick your brains . I have a 1990 1.6 td bus with about 103,000 on the clock. The engine was replaced before I got it with a low mileage 1.6 td from a golf. When the ignition is turned on the red led on the gauge glows( DOES NOT FLASH) and when the engine starts it stays on. The actual needle moves to about 1/2 way after a couple of miles driving and stays there. The bus uses no water or oil and drives fine with no signs of overheating( even after 160 miles of motorway driving)......Any suggestions please.

As Chris suggests
sounds like an earth fault or faulty sensor.

Ah ROB your sympathy is so refreshing..... we will try not to sneeze across the Park in your direction.

Assuming that yours is supposed to flash bear in mind that the circuit that controls the flashing is in the temp gauge itself. The LED should flash for a few seconds as soon as you switch the ignition on for a few seconds. Even with the instrument housing removed and just powered up with 12V it should flash and then extinguish. The coolant sensors trigger the gauges internal circuit. Yours is glowing and I doubt that the problem is the sensors particularly since the gauge functions normally.

Hi,, sorry to butt in but i have a similar problem too on my 2.1, coolants fine, temps fine just this damm flashing light constantly,,,, does any body know if there should be 12v at the sensor plug when the ignition is on?? blue and green wire on mine traced this back to the harness conector which i seperated and no 12v there either,
