    The other day unlocked car and drivers door wouldn't open went through back door and opened with ease drove 12 miles or so to work and it worked fine when I tried it at work now this morning the passenger one did at the misses got a strop on as she thought I locked her out in the cold lol but again opened fine from the inside ??

    Is it just the cold weather that's freezing the lock or is it a problem beginning to start ?

    Any suggestions ??

    I would of thought air driven of the pump and electric side is just to let the comp no there's a fault or the doors are open for courtesy lights etc may be wrong though lol

    I think the change over was about the FL time.
    PFL was air pump driven and FL was electric. I think.

    If yours is a PFL, it will be air. so you could have a leak or something freezying stopping it from opening.
    The VCDS will tell you if there is a fault with the pump, like if it ran on for to long which will indicate a air leak.

    Mines a 99 and still prefacelift :)

    I think you'll find all b5's have air driven locks. Its only the tailgate/boot of the facelift thats electric

    I thought FL went electric all round along with the boot.

    You can tell if theres a leak by listening to the pump.

    If its fine it whirrs for a couple of seconds at most. If its leaking it'll whirr for ages, 10-15secs.

    If you dont fix it and it is a leak, you'll shatter the impeller in the pump.

    it will be the central locking pump mine has been faulty since i brought mine, it a 2000 faclift, when i first striped the pump cause nothing work the impella was shattered, so i got 1 from the scrapy, and swaped the impella over as they are coded to car so would need vagcom or someting to install! so after the swap i got my door to work but none of the rest! my door was perfect for a few month now if i unlock it only half unlocks it but if i pull the handle a few times it opens! best bet is your local scrappy, as the ones on ebay i think r a little expensive, i paid 10 from scrapyard! there seem to be 2 vacum lines on mine think 1 is for drivers door and the other for the other 3! hopes this helps abit!

    You can by impeller kits off Ebay.
    I'd buy one of them over a breaker unit.

    Buy a "4A0" pump from an Audi 80 or similar and swap the compressor from that. They're much sturdier.
