you state you need specialist equipement to do this mod , basically you state that it needs the eeprom editing in the dash cluster to enable it . please share the locations in the dump and the new values that are needed as this can then be done with a cheap eeprom programmer and i little knowledge not $2000 of equipment . i would like to test youre theory on a a3 2010 tdi cluster . i have the resources and if it is only eeprom contents of the 24c32 or the 24c64 eeprom then it is actually only a few minutes work.
i have info that these are the actual locations that need to be changed at to these values ,however it would be nice to confirm this before i pull out the dash and open the clocks to try .
