IIRC this can't be done though editing eeprom

Link to videos?

This is the the first time I see/hear about it.
Seems like a promising little project

212 : Was F4 Set it to A7
213 : Was F7 Set it to 10

281 : Tachometer Scale - Was 00 set to 10 this will scale tachometer right to the end.
269 : Speedometer Scale - Was 00 set it to 10 this will scale speedometer right to the end.

Speaker has been disabled by changing values located at:
204,205,206,207 to 00

To fix DEF issue displayed next to millage you need to calculate checksum for speedometer map. With VCDS or VAGCOM go to Instruments - Recode - Do it.

OP is using a B5.5 Passat cluster. It's possible the locations/values are different between that cluster, and yours. A bit surprised there are no cluster part numbers anywhere in the thread. Not sure what cluster type/ part number the info Marty posted pertains to. Anyway, thanks for posting your results!

seems that he basically changed speedo / tacho start position
then ign on needls goes to max values and of course never goes back
funny but useless
