Default Alarm going off and doors not locking...anyone got a solution?

Hello all, I have seen this a few times recently I assume it’s due to the wether.

My Cowley build 75 is having some alarm / locking / throwing a hissy fit. Early on this evening I realised i had turned into basil faulty...standing shouting at it ....

A week or so ago the hazards starting flashing and you could hear it trying to lock itself even though it was already locked.

The rear drivers actuator is abit iffy...

Fast forward to tonight and the alarm starts sounding. First time it’s done this. So I unlock it on the key and then lock it and all I hear of the bleep to tell you something is unlocked. So I go outside and check and the cars locked. All the doors are shut and on further investigating it’s only locking the drivers door.

The rest are jot locking. But it’s been locking all of them. So I don’t think it’s to do with the door actuators.

Drains are clear and it all seems to happen when wet and cold. It all started after a very cold day i between Xmas and new year.

I’ve had a look on here and seen talk about body control unit under the dash behind the glove box and also the bonnet switch. Has anyone had this issue and managed to resolve it? If so what did you do?

Thank you

Josh

Had this issue exactly, and no, haven't solved it. Mine did it around 8pm and it was dark, only had the car a couple of days. Disconnected the horn, disconnected the battery and left it overnight, it played up a little the next day but then behaved as normal. Can only imagine it was water ingress.

head over to see Big Russ and have him interrogate the alarm log with T4 as save yourself a world of pain.

It won't be the BCU at fault though

Could it be that the actuators have got damp/wet in the doors, and frozen in the cold spell we have at the moment. Same when you get in the drivers side only, and the door won’t stay shut, or shuts but the warning light on the dashboard says it is open. All down to elektrickery I am afraid. Same with the reversing sensors when covered with snow, when in reverse they just keep sounding even when you can see there is nothing behind you. Knock the snow off and they stop sounding. Simples really.
