    Problem with multiple exterior lights on 2008 Caddy

    Hi all,


    I have a 2008 Caddy Maxi 1.9 TDI.


    About a week ago a number of exterior lights stopped working.


    Passenger side - headlight, rear break light.
    Drivers side - rear indicator, low beam, fog light.


    I have tried replacing the bulbs but this hasn't made a difference. They all stopped working at the same time which is has to be too much of a coincidence for it to just be the bulbs.


    Somebody suggested to me that it could be a water leak in the ccm/bcm?


    Does anybody know where the ccm is located and how I might fix it, or have any other suggestions on what my problem might be?


    Thanks all

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

    Post moved to the correct section as it isn't a maintenance problem.

    You need to start with a fault code read of the central electrics system, AKA BCM.

    Update***

    Issue resolved - it was a blown fuse in the fuse box next to the battery. Simple fix thankfully.

    Thanks for the help anyway

    Its proper name is SB17 as it is in fuse box B and the S stands for Sicherung which is German for fuse. It is 15 amp rated and the power exists the fuse box at plug T40 pin 18 as a 2.5mm CSA red/brown wire and it's single purpose is to power the J413 horn relay.
