Hi, guys! recently had to swap cluster for one of the friends. on his A4 it was burned (8E0 920 900 L). He found 8E0 920 900 H... dumps are different - so I just adapt new cluster, learn keys - car starts and run... almost everything works. Only 1 issue - speedometer stays at 0. (cannot confirm behavior before - cluster was fried). and ECU has an error about missing speed signal. on the car did not find speed sensor (manual tranny) - there are a factory plug.  Mitchell diagrams shows controversial info - there are no sensor for those years - assuming take info from ABS... is it possible replacemt cluster came from the A4 with the sensor and issue impossible to fix?

cannot say what car was the donor. But most likely this is the case. Strange that cluster does not indicate any errors about missing sensor - but probably sensor check on cluster different from ECU and its not recorded as DTC

the way I see safest method would be desolder eprom - save what inside - solder back and then play with vag eeprom program - the only one from cheap programs seems to be working with crypted rb4s
