Question about 1996 Audi A4
Toyota AE101 Corolla Seca 1998. Key will unlock all doors, but key will not lock any doors except the drivers side. Can I fix this myself ?
If the A6 layout for the modules is the same as my A4, the lock pump is in the rear corner of the car, on the passenger side. In the trunk, pull up the carpeting behind the passenger rear wheel, and tucked down in there is the pump assembly. They're known to go bad and it's a pretty likely cause for your problem, provided your fuses are not blown.

I had exactly the same problem and there are 2 ways of solving it. The first is to pay your Audi Service Centre £350-£550 to replace it for you and the second way is to do it yourself which will cost well under £100 (depending on ebay). Firstly check the Central Locking Pump to make sure the hoses haven't come off. This is located in the very back right hand corner of the boot so you will need to remove the carpet and internal trim and you will see a block of sponge. Carefully lift the top off this and you will see the pump sat inside it.
Actually there is a great set of photos online to help you and I will add the link for you at the end. If the hoses are still connected and not leaking it is very likely that the internal compressor wheel has shattered (quite a common fault). I believe it is possible to open the pump and replace this wheel (in fact there is one for sale on a very popular auction site at the moment) but my own preference was to simply buy a whole new pump and replace that (£16.00 + £8 p+p off the same auction site).
The most important thing for you to remember is that when you look to buy a replacement pump you need to find one with the EXACT same serial number. The one in the diagram shown is
8LO 862 257 N but I have a sneaky feeling yours might end in an A.
Anyway, I hope this is of some help and dont worry about the connections as both air connectors and all 3 electrical ones are different sizes and will only fit in one place each.

As far as the central locking issue, it sounds like you need to replace your central locking pump. You can buy them online.
I have a 95 A6 and I am in the process of looking for a new central locking pump.
The part number may be 4A0 862 257 J, that is what it is for me.
There are directions online as to how to change this yourself once you get the part. If you buy from the dealership the part is $500.
Be thankful your child locks weren't engaged. We haven't been able to open our back doors since the pump went out.

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.
