OK, use your Bentley (you do have one, don't you? if you don't, use this instead: http://ep0niks.ctech.ca/vw/eva2 ). It'll tell you where the oil pressure switches are. Try switching them around. If that doesn't help, switch them back and try replacing them. If THAT doesn't help, then look at the cl...

I think it was intentional. :lol: The tranny reverse switch has nothing whatsoever to do with sending RPMs. It has two functions. One is to turn on the reverse light in reverse. The other is to turn OFF the upshift light in reverse, neutral, and fifth, no matter how many RPMs the upshift circuit is ...

Clean your reverse switch and see what happens. (I need to do that to mine, because, umm, the reverse light only comes on when I'm halfway into reverse, and turns off when I'm fully in gear. :oops: ) The "exactly 2100 RPMs" thing... My theory is that something is causing the OIL light to b...

Interesting.

Does it do it in fifth or reverse?

I have a theory involving crossed wires here.

The upshift light comes on at 2100 RPMs.

My upshift light actually burned out.

If your upshift lights are burned out on original clusters, check your reverse switch. Not only does it turn on the reverse light in R, but it also turns off the upshift light in R, 5, and neutral.
