Bit of longshot, but does anyone have a dump of the EEPROM from a Golf MK2 MotoMeter cluster with MFA?
I currently have thread going on ClubGti trying to find out what is causing the MFA and Rev counter not to work on these clusters, even though clock (ran by the same processor), works fine.
I think it could be something to do with the EEPROM data becoming corrupted as they are it rated for 10 years, and some of these clusters are approaching 30 years old now.

So if anyone has any dumps, or another idea what it could be, then that would be much appreciated!
