Doors not locking on 08 5 door tdci mk6

[frund]

Sometimes they lock. I read a search on here and a chap changed his door loom and it was still the same. The last time it would not lock I wiggled the drivers rubber boot  and it locked. Earlier i closed the door a couple of times and this worked. 10 years this door would have had a lot of use. The rubber boot looks like new could it be a short somewhere.

Any ideas ta

more likely a broken wire than a short (like the plastic sleeve is still in one piece but the copper inside is breaking)

Yes may well be broken wire. I should have said it locks then unlocks  immediately. Once I get it to lock it stays locked then it may be ok for a few times then the problem reoccurs. 

I have not had a chance to look at it yet but I would have to cut the rubber boot off by the look of things.
