Just bought a 2014 superb,  after 1 week the drivers door wouldn't open with the central locking,  had to open from the inside,  closed the door and tried again, door opened and worked for about a week then did it again and has done it a once more. Anyone got any ideas ....it's not the cable like I've seen on other questions about locks.  It's ok for a week then happens just the once then it's fine for another week 🤔 any help much appreciated. 

It is unlikely to be anything other than the wiring loom. Often the cables are still held by a part of their insulation so intermittent operation is common.

Though it was wiring related, I'll have a look and thanks. 

Lots of threads to be found on here about damaged door loom wiring.
