Central locking intermittent fault on drivers side central locking but can open with key. Constant fault on passenger side and will not open with central locking. Also passenger side electric window now not working. With the central locking you can hear a click but the buttons do not pop up. Sometimes as you drive away the door locks and button goes down as it should do but on passenger side it doesn't.

i had the same problem and i fixed it yesterday. you will have to strip the door down and remove the central locking unit. expect about a 3-4 hour job (at least).
check this site out taligentx.com: Passat - Door Lock Mechanism Repair. its **** hot.
mine had rotted inside, i tried to resolder it but it was to corroded i ended up soldering wires to the circuit board and splicing the into the loom on the door.(bit of a botch but it works great)
you can get a second hand unit if you cant fix it for about £50/£60 or pay a garage about £300 to do it.
believe me it was worth about 4hrs and gettin peed off to save the money.
hope this helps.
emptyed : )
