[list]Help ! I have a 2010 Range Rover L322 tdv8 3.6 FSH. The passenger side rear door lock is not operating via the central locking system, main dash switch or remote fob, and the window works erratically. The door will open manually. There are no obvious faults when the door panel is removed and all multiplugs have been removed and cleaned. The Launch reads Fault code B1A98- 87 Interconnection bus network Circuit 1.
Bus signal / message failure. Has anyone experienced similar faults ? Could this be a goodwill warranty issue ? 4 year old car with full dealer history.[/list]

mist, definitely warranty but also could be the cold weather, plays havoc with door mechanisms, have a search
