Hi when I set off driving all the door lock but as soon as they lock they all unlock apart from drivers door why ? Should they all stay locked till I stop or press unlock button on driver door ?

They should stay locked until the keys are removed (providing it's been coded correctly).

If the car is locking, then unlocking it's miss locking. It usually means something is open (like the boot) or at least the car thinks it is. I would have a look at the measure blocks with VCDS and see what the status of the system is to see if anything is showing open.

It locks ok with the fob just the driving is it a mod done after or dose the car come standard with this
