I tested the motor by means of putting a 12 volt pulse to the wires and both lock and unlock works in that way.

I put in a brand new duracell 2032 in the fob, but no luck.

When I manually lock the doors I can unlock it with the fob.
Locking with the fobs used to lock the doors, and the alarm led started flashing rapidly, and after about 10 seconds started flashing slowly.
Now, when I use the fob and press the lock button, I hear the pektron relay clicking, doors do not lock, and and also no rapid flashing of the alarm led, however after 10 seconds the led does start with slow flashing.
When I lock the car with the key manually, also central lock does not work, the passenger door stays open, but the alarm does now work with fast and slow sequence.

So what I can rule out here : lock motor, fob battery, reception of fob signal (fob relays clicks both at pushing lock and unlock fob keys).
I have found a complete wiring schematic, next is to test the micro switches of the lock.

For the MOT the garage did some repairs on the wiring loom for the brake light in de boot, near the hinge the wire was broken. I checked the boot light, still works, but if the boot lock microswitch is somehow connected to the pektron, could it be that a broken wire is preventing the lock because the pektron thinks the boot is open ?

2 years ago I replaced all my pektron relays with good quality new ones, even made an how-to, so I am having a hard time believing this is again broken, but surely I will check, or just send the unit to Paul.
It is a weird fault, just appeared out of nowhere, worked fine, until just at once, could not lock the car anymore. No warning of intermittent failure.
