Belt force limiter / airbag control lights up !

Hello together ! For the second time the airbag control in the speedometer is leaking. The first time a “repair cable airbag” was installed on the passenger side; afterwards everything was in order – until now ! My suspicion : Is now the driver side affected !? Before I go back to the workshop (they already know me well), question to you : Have you had experiences with this problem; what helped (wire harness, ECU, etc.) ? Do you have any other electronic problems? My MINI is from 10/01 by the way. Thank you very much!
