1998 Audi A4 Central Locking Fault

[smallville]

Hi, I need some urgent help

I have a 1998 Audi A4, 1.6 petrol.

The central locking does not seem to be working. I went to open my car yesterday and it did not open. I normally use my key in the lock to unlock all the doors.

I could unlock the boot but not the doors.

Now I have got back into my car, and can manually lock all the doors except the drivers side. The key fits and turns on both the drivers and passengers door but does not lock the car. Same applies to the boot, I can not centrally lock the doors by closing the boot.

So obviously this leaves me with my drivers door open at all times.

If anyone could help me out as to what to do, I'm a 'skint' student so can not really afford to take it to an autoelectrician until i review all my other options.

any help would be AMAZING

Many thanks

Ok I've taken out my central lock pump/motor from the boot of my car. And had a look inside. The graphite disc looks in tact, but the Foam surrounding the pump was VERY wet, and the surface of the pump itself was damp? Would this explain the above?
