DEF message is normaly al wrong dump in eeprom..You can try to recode the cluster or write the original file to your cluster.

Fail in display is mostly a locktime problem, please make a printscreen from measeringblocks 022 - 023 and 024 ( 17-Instruments )

024 everything must be 0 - 0 - 0 - 0, when no, when you see 9 - 0 - 0 - 0, let the ignition on for 9 min, then login with the right pin en adapt the cluster to the ecu and match the keys..You need both logins from the new cluster and the old cluster.

Let us now..
