Central locking popping open

[peterchurch]

Hi,
I was driving down the road the other day and my central locking popped open (both the doors) so I locked it and carried on and thought nothing more of it. Then it happened twice yesterday

Has anyone else seen this happen ?

Regards,

Peter

could be the door switch being dirty? it thinks a door is open, so unlocks the doors...

Wouldn't that make the lights come on as well though? There is a thing in the user manual that states that the doors will unlock in the event that the car is in a hard enough bump. Could I be tripping this by driving too hard on the bumpy roads ?

i think the doors unlock in the event of hazadous driving dont they? ie if your ABS or ESP comes on or something....

Yep, well there's some functionality whereby the doors ar eunlocked (& I think the sunroof & windows closed) if there is a violent manoevure. I don't think it would come on with the ABS and it doesn't happen when the traction light comes on ;-)

I have experienced the doors unlocking after hitting a MAJOR pothole, luckily it didn't kill my AMG's but it sure is a shock to see the car unlocking

my sprinter locks are a bit dodgy, and the lock needs to be locked three times - it 'feels' like the lock itself is sticky, and the servo is pushing the lock over to 99% of the way - on the first two times it only goes to 90% of the way, and immediately unlocks itself.

maybe the lock is a bit sticky, and a slight bump knocks the lock back to 98% locked, which trips the switch, unlocking the door...

total guess - but a quick squirt of WD40 into the lock cant hurt...
