Doors locking/unlocking when driving

[dErZ]

The last two times I've taken the van out all the doors unlock/lock after you've gone below a certain speed ie driving at 40 come to a stop/slow crawl (cant remember what speed its set to lock them poss 10mph) unlock/lock..this happens for the whole journey.

Any ideas?

Could it be that one of the door solenoids has failed. When that happens the doors unlock immediately after you lock them.
Then, because you’ve got the auto lock function activated, every time you’ve dropped below 15 and you speed up again the van auto locks/immediately unlocks and the cycle begins again.

Sounds like a faulty door latch or the micro switch inside it. Either way it could do with being plugged in for diagnostics buddy
