Nice looking car, Red cleans up really well.
I would imagine the Rev Counter is a trapped/broken wire or something similar.
Big fan of M cars and Michael Schumacher.
It must be the wire from the ECU to the rev counter. All out gauge faliures are pretty rare although I would start by removing the rev counter. (Remove cover on top with flat blade screwdriver then loosen philips screw and it lifts straight out).
The loom may just have come loose. Worth checking for 10 mins work.
