(Have started new thread as was unable to edit the 'fix' comment from original thread).

After Locking/Unlocking the vehicle, Door opening became problematic once again, and now will not open.

It is as though Lock Assembly is locked within itself?

Fault Code: A6E8 not present. JBE Central Locking, repeat interlock.

To clarify: When Plip is used to open Door, the solenoid is audible opening, and the door button lifts to the open position. Using outer/inner handle, no resistance is felt. It is locked.

(Incidentally, when new Door Lock was fitted, if the Door was not locked with Plip or pressing Lock Button down, the Lock worked perfectly).

Wiring problem perhaps?

Checked Fuses in Engine Compartment and Drivers Footwell. Is there a Fuse for each door

Are any of the release cables too tight?(over adjusted).Inner and outer door handle release cables ,is there enough slack.On the VW latches,inadequate movement of the cables does not allow the latch to complete it's throw and the mechanism gets stuck halfway between lock/unlock.Just a thought.

Did you check for broken wires across the hinges?

Thanks for replies.

Fault was Door Handle Cable which had got water ingress and lengthened cable, causing latch to not be adjusted in the off position, correctly.

Fitted new Handle and Cable, complete.

Cheers,
Ian
