    Hi all,

    I recently aquired an S4 1998, and there a few issues with it, most i have sorted, but the one issue that baffles me is the central locking, and the keys.

    Basically the Central locking does not work, i out in the key and turn the clock, and it only locks the door i have the key in. The pump is connected but makes no noise at all. If i keep the key turned long enough then the windows will go down, or up depending on unlocking or locking.

    Any help is appreciated

    I would imagine the CL pump is faulty. Probably the impellar has broken up if you listen closely in the rear drives side of the boot you will probably hear it.

    ok just to update, listened to it today, and it does nothing and makes no noise, took it apart, and its all intact, just out of curiosity i noticed the power connector can be connected either way so i tried this, result was, stereo started to play, but windows no longer went up or down via the key, and central locking still didnt work. I am now very confused

    if impellers intact id say you have some electrical gremlins
    where are you?

    ideally you could do with trying a different pump should be an 8L0 'G' fitted to a 98
    if you cant borrow one they usually go for £40-50 on ebay

    easy enough to sync fob if you have 2 keys
