I had the black top engine mk2, I live at Taiwan.
I had encounter this situation for many times, cause of the humit
and moisty and heavy rain weather here.
It's mostly the program tangle up, just disconnect the batery negative and live it for few hours and then reconnect it....buala fixed instantly,
fresh like new. But sometimes the program really mixed up, so U has to
do the procedure again, but this time U has to let the disconnections for much more time, like over night..

if this won't help, check for the door rubber tube connected to the car body , sometime one of the door eclectric rubber tube might be loosen
I had one time on this.

if not of all above, then one of the door locking system fail. U had to buy an new one,no other ways,but door locking system are very durable
only very little chance it would fail, mostly are the above symptom cases.
