The central locking is not working at all from the remotes.
The batteries are fine and the led on the remote lights, have tested with remote tester and it seems to be outputting a signal.
Have tried the synchronisation of the remote but nothing happens (indicators don't flash)
On VCDS the remote section shows no change when remote buttons pressed.
Do these cars suffer with control module problems ? Is there a seperate reciever unit (Aerial) in the car i could check or is it more likely that the code has been lost between car and remote (erased)
The CDL works fine from the button on the centre console.
There are no fault codes present in any system.

Many thanks in advance
