Solenoid for central locking?

[Yourboyluke]

My passenger door has to be manually locked/ opened. I've fitted a new paddle shaped part (a common fault) to the door handle, but it still doesn't work.

There's a White box midway down the door which I believe is the opening/closing mechanism (solenoid I think)

Can anyone suggest what might be at fault here? Or does anyone have similar problems that might be able to advise with this minor, but annoying problem?

I've tried searching the forum, but I don't know what the fault is, so don't know what I'm looking for..

Cheers,

Luke

The mk4 and mk5s have pneumatic central locking IE air powered, therefore no solenoid. Check the yellow/white air pipe that runs between the chassis and into the door to make sure its not split at all.

Thanks for replying. You 100% sure This model: http://www.parkers.co.uk/cars/specs/Det ... eriv=10672 has the pneumatic central locking?

I only ask because someone else is saying the problem is electrical. I just need to eliminate all possibilities
