2003 audi allroad. central locking stopped working one day for no reason, new battery in fob still nothing, drivers door lock feels like its not connected so have to lock/unlock with boot lock causing alarm to sound until key is in the ignition. drivers door will open after some gentle wiggling of the handle, other doors unlock and open as usual. the interior lights are flashing on and off also, would it all be linked to the ccm being wet or is there another problem? ive done some interweb searches but come up with different answers. has any one had this problem before and managed to fix it quick and cheaply (if there is such a thing with audis)
