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?

if the cluster is from a 2002 b6 they still had mechanical speed sensor and not from canbus

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

so got another cluster with same number as original - 8e0920900L.  (not sure if I can get old broken cluster fast to simply swap eeproms)  Tried to get pin with commander (only got it with 1.4) - it seems like read dump but cannot recognize it obviously (tried with different options). Can somebody advise if its good dump (it does not look crypted - but..) or I have to desolder eeprom. although still not sure what tool to use further to get pin and adjust mileage to original 130k. Thanks in advance! dump attached

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

nicely done all required with vag eeprom
