Command intermittently shutting down

[oldmerc]

W220 S class 2005..as per title..fault occurs when vehicle moving or stationary..it reboots with Merc symbol within one or two seconds of failure without any input from myself..not sure if this problem is linked to other faults I'm now experiencing for example..wing mirrors not folding out when opening doors with key fob..all door locks not opening when exiting vehicle ?

get a fault code readout to find the actual problem, did u add maybe a tv free module or anything you added onto the car lately?

There have been no upgrades or mods carried out..a friend who works for BMW recommends looking at convenience/body module which is situated under passenger seat..maybe it's a trip to commandonline in Surrey to locate the problem.
