    C/locking pump problem

    Hi,
    I have an A4 1.8, 97/P reg, that has a problem with the e/w & c/l (they dont work at all). Anyway, I checked in the boot rear 1/4 area and noticed that the pump unit for the c/l was missing. I managed to borrow one from an A3 with the same connectors etc. and it appeared to do the trick...until the indicators & fog light switch on the dash started flashing (silent alarm?). Also, the c/locking stops working once you've closed & opened the doors for the first time.
    If I disconnect & reconnect the unit it seems to be ok until you open & close the doors, then the indicators start flashing again....

    Any ideas?

    Great site btw!!

    Cheers

    Sounds like some sort of relay problem to me?.........do the electric windows work ok?

    Windows work fine.
    I thought that even though the unit from the A3 (1999 model) fits the A4 (1996/7) that there may be small differences in the wiring in the unit itself which could upset the A4?
    You mentioned a relay, how can I rule this out?
