Hi m8!!!

For the 330i E46 series Dash it need to remove the needles, welded on the board there is an ST 35080 eeprom (is recommended to have a new of it, because not all types are erasable), necessary only Dash correction to decrease the kilometers on the display, however for a good job is essential to correct value on EWS and LCM (EWS is Immo ecu, LCM is light modul) because with of diagnostic tool is possible to read the old value of the km. With X-prog you have a good tool for to perform well the job!!!!!
I hope to have help you, my English is not good!!!!

Best Regards
Fab

needles come off easy
and yes you can read in circuit but is better to remove eprom.
