Also check the larger oil switch/sender is the correct type. There's one with 0.3 bar switch and one with a 1.8 bar switch, yours should be the 0.3 bar type.

I didn't think the temp sender went to the auto check....?
Anyway, there's a load connections under the dashboard which I found to be corroded a little, had bugged me for years but always solved itself once the car dried out in summer.
I finally solved it when I found those corroded connectors and gave them a good scrape and contact cleaner.

You know what, I think your right there Peter... If the wire for the temp gauge isn't connected the gauge reads flat out but I'm not 100% sure it's linked to the Autocheck.1989 B3 2.0 3A 80 quattro... Budget 1.8T Project.

One's a 7A and ones an S2, hence the differences, though I think Peter's suggestion is still along the correct line of thinking. Check any ground points you can find and the wires going to them as well any other connections under there that lead to the clocks.
I bet it's something really simple, just a case of finding it.1989 B3 2.0 3A 80 quattro... Budget 1.8T Project.

How do you mean ?? Lead to the clocks ? ... i have already all the ground cables under the dash harness,, a lot of grounds. So its probably somekind of ground or cable issue of some sort ? The cables that goes from the fat oil sender those cables is that i should correct ? As i have searched a lot .. that is the sensor that makes the lamp flash .. hmm if take it out i can test it manually ... plug the hole int the block .. and put air pressure on the sensor , i have rig for it. Thats how i tested they worked before installing them. Hmm
As Peter says above you really need to find the wires from the pressure switches to the Autocheck and test them for continuity, one could be broken or earthing out on the body.
I can imagine it being really frustrating to find this problem but I expect once you find the solution it will be obvious.1989 B3 2.0 3A 80 quattro... Budget 1.8T Project.
