BMAX Central Locking Failure
Summary of the thread
The central locking failure in a 2013 Ford BMAX diesel was initially suspected to be due to a fuse or a larger electrical issue, possibly in the door latches. A similar problem in another vehicle was resolved by identifying a bad cable or plug connection to the door contact signal. The suggested solution was to check the door wiring, particularly the connectors, for corrosion or loose connections. Ultimately, the issue was confirmed to be a defective cable or plug connection, which was repaired.

That's interesting. No recent electrical work or bad weather here. What was the problem with your Astra, and how did you fix it?

After a lot of messing around, the shop found a bad cable or plug connection to the door contact signal. The Astra's door latch had a similar problem. I'd get the Ford's door wiring checked, especially the connectors. Could be corrosion or a loose connection, but it's probably best to let a professional handle it.

Thanks for sharing your experience. It turned out the BMAX had a defective cable or plug connection to the door contact signal, just like you said. The repair was 95€.

Funny you should mention that, I had the same thing happen with my 2016 Opel Astra a few months ago. The automatic locks just quit. Did it start after any electrical work or bad weather? I was pulling my hair out trying to figure out if it was a faulty car sensor.
