Another issue to sort out (one of many lol). The boot on my estate stopped opening with the central locking. I can open it with the key no problem and that activates the other doors.

The solenoid is working with 12v but I am only getting 3v odd at the wiring. Could this be a break in the wire or something more sinister?

Cheers

May be low voltage due to a bad connection with some corosion or perhaps a poor earth. If theres 3volt there the wire I assume is still intact .

That's a good point. I'm not exactly how it works, cos it's a 2 way solenoid, so flips the 12v and earth to open/close the solenoid.

Hoping to get a chance to look at it tomorrow

I assume if it was a short that was losing the 9volts it would blow the fuse. Might be worth checking the fuses arent loose or coroded as well . As said under no load even one strand of wire would read 12v.

On my MK2 the central locking does drivers door and requires a second and sometime third press of fob to open boot. Just wondering if yours is the same?

tried it multiple times over days before I removed the cover and checked the voltage :(
