Central Locking Woes - 2004 Allroad

[Chris1573]

Had my key apart last night to replace the battery as I noticed that I had to be quite close to the car to get open the doors with the keyfob. Only took a few seconds to switch over the battery however afterwards I could not unlock the doors using the fob. In fact nothing is working on the fob, I can only open the drivers door manually with the key. My spare fob has not been working for some time so I can't use that one either.

Tried the various key sync suggestions ranging from press button once then unlock to resync (from audi handbook) to putting one key in the ignition and turn on the ignition then close door, lock, press button once then once again etc etc. However I am not getting anything no indicator flashes, nothing....

I have tried another battery and still nothing.

I have tried to connect with VCDS but whilst I can access the main modules ok (engine, gearbox, Instruments.)I cannot get a response from any of the below:

09 - Cent. Elect.
19 - CANGateway
35 - Central Locks
46 - Central Conv.

Does this mean I have a bigger issue ? why has it suddenly started like this....

Without seeming like a smartypants, you might get a better response by posting in the A6 forum section
