Audi Central locking pump compatibility?

[e.bug]

Hello,

I have an Audi A3 2001, and my pump is dead. I have 8D0 862 257 "B" and i can't find it anywhere. I want to know what other part numbers are compatible with mine. What about 8L0 862 257 or 8D0 862 257 with other letters on the back?

Thanks

I think its compatible you just need to reprogramme the keys. I have the same problem right now.
