BMAX Central Locking Failure

Could be, but that's like asking if a leaky faucet is just a bad washer. Have you checked the fuse box? A blown fuse can knock out the whole system. Any issues with the car alarm or keyless entry?

The fuses look fine. Is there a common point where the cables are defective?

It’s possible, but without proper diagnostics, it's like searching for a needle in a haystack. Given the error code and the symptoms, a defective cable or plug connection is plausible. I'd advise visiting a workshop.

Thank you. The garage confirmed a defective cable connection. Repair cost was 95€.
