Gauge Cluster Instrument Problem R34

[427]

hey mates, searched for the other threads and didn't find the way to solve the problem.
so i had this issue before but after some time it had fixed itself
my speedo, milegae, tacho and water temp are not working, the rest things are working
once it turns on (speedo, milegae, tacho and water temp) but after 1 min working turned off again.
i checked computer for speed pin connection, there is blitz power meter id connected - everything is ok with conenctions. on power meter there is also no information about current speed.
i checked the fuse - 'meter' in the interior fuse box - it's ok
i took off the cluster and checked for the fallen off connections - all is ok

could you please tell me where to check? also there is check engine sign appeared

thanks in advance

PS now the cluster working and check engine sign turned off. one thing i noticed - when cluster has malfunction the door when opened has sound signal (like when you leave lights on after turning off the ignition), when cluster is ok there is no such signal, only flashing red lamp of alarm
