I've seen a few posts on here about central locking not working, locks bouncing, doors locking and unlocking straight away and the common cause seems to be the Bowden cable that runs from the door handle to the lock mechanism. While I was sorting a squeak in my passenger's door today I thought I'd take a couple of photos to illustrate the right and wrong way to put the door back together, if yours has started playing up after fiddling with the doors.
It's very easy to get wrong. All you need is one jiggle too many when trying to get the door card to sit right on the sassenfrassenrassen mushroom locator thingies
and the little collar can pop out of place. So be patient and check the operation of the lock at all stages
God bless Alfa, three different size allen bolts to get the card off
They're almost all different lengths too, so keep track of which comes from where! You don't actually need to remove the lower door pocket, just the 4mm bolts along the bottom. Two more are hidden behind the speaker and the 5mm one is behind the window switch which just pops out when prised with a flat screwdriver.
When all the bolts are out the card lifts up off the mushroom mountings and is free. Careful with the tweeter and puddle light which can be left plugged in if you only need to get to the cable. Refitting, as they say, is the reverse of removal. Just mind that collar!
