: Central Locking Problem.

06-16-2011, 11:03 AM
I have a 2004 A6 2.4SE Avant, the remote key will not work either to lock or unlock the doors. I can open the drivers door manually with the key but all the other doors remain locked including the fuel filler. I can manually open the doors and when I then lock the drivers door, all the doors lock. When driving I also have a constant ticking noise from the dash, sounds like a relay. can anyone suggest what the problem can be and how to rectify the fault, thank you.

I have been reading on Audi Forums and wondering if it could be a control module under the passenger floor, it seems they are prone to leak around this module. Please can anyone advise where the central locking control modules are located
