Audi A6, Central Locking unit problem..

[pakstar]

My audi A6 stood for 5 weeks in winter, after coming back from Abroad I noticed that central locking has stopped working as battery was also flat, but even battery was back on charge central locking unit won't work.

After reading the forums I realised that there is water under front seat's I went to mechanic, he drained water and dried central locking module but REMOTE central locking won't work. He finally replaced central locking module ,but still no joy, as remote central locking won't work even with differnt module also (maybe other used module also faulty).

Symtoms.
Remote CENTRAL LOCKING Stopped working after water sneaked under front seat and back seat.

Central locking inside doorbutton works fine when ignation is ON.
All windows works fine EXCEPT rear side rear window.. maybe cable fault ?
all lights in dash board works fine. Fan works fine, Climat control works
radio works fine, interior lights works fine, etc
Outside driver door manual locking works with central locking (Still REMOTE key won't work)

I tried to syncronise the key with differnt methods found on fourm but still not joy..


Solution?

1. HOw i can completely drain water if there is any more left and how to permanently stop water next time?
2. Is central locking unit can still be faulty when other related functions are working ok?
3. best way to dry the carpet..

anyone care to reply..

Many thanks in advance
