!!! 1P0920841C Leon 1P Cluster unrecognizable keys !!!

[eliotroyano]

Hi friends. I have a big problem with the indicated cluster (eeprom content is attached). Keys are not recognizable at all. Inclusive it does not indicate any trouble codes at all. We try to rematch old keys and newer keys without any luck. Reader ring and keys was tested and everything is ok. Inclusive a 2nd cluster with it related key was tested working quite good. Friends can you send some tips what can be happening there?
Thanks,
Eliot

Basically it is not recognizing any keys. ECU is already immo off. I test another car cluster + keys and everything is ok. Reader coil and keys are ok.

Likely the transponder base station chip in the cluster is dead. This is an occasional problem seen on Micronas clusters. Do an immo data transfer to a donor cluster using a tool like VVDI or Abrites.
