1989 100 quattro check system probs - ses
My 1989(G) 100 2226cc quattro has developed a fault. I would appreciate any comments. The on board computer works fine(mpg check, miles left on fuel in tank, distance travelled etc etc). However the Auto check system which gives the OK signal when car is initially started, gives three audible signals while driving as well as displaying a RED water temp symbol. The red signal was once displayed as the oil symbol but usually is the water one. There are no water or oil related problems which leads me to suspect that the auto check system itself is at fault? Any comments or opinions from Audi specialists would be more than welcome.

Perhaps the coolant level check system is up the spout. It was on my '88 Golf.

I unplugged the control unit where it now rattles around in the glovebox, and check the water level the old fashioned way.
