Hi all, I a newby to the forum.
My MMI display and system has gone blank/dead on my 2008 3.0L Tdi Q7. I have be reading about the MOST bus and bridging each unit with a fibre loop device to find out which unit is faulty. How many units are on the MOST fibre loop and where are they located/positioned within the vehicle???
Any help would be great to see if I can find the faulty unit.
Thanks
John

Depends on the options you have. I would start at the modules next to the right rear cargo / quarter panel area. They are pretty easy to get to and are the most likely culprits.
