The BCM in the SL class (Mercedes chassis code r230) fails very often. It catches fire and burns down vehicles in MANY instances. Mercedes is not selling a replacement part because they want to save money. THIS VEHICLE HAS AN ELECTRONIC ASSISTED BRAKING SYSTEM!!! The BCM balances battery loads in the vehicle. When it fails it can make any electronic system in the car malfunction or simply not work. This could be as simple as the car not starting or as severe as it burning down your ENTIRE HOME. I would be okay if they simply sold a replacement part but they DO NOT forcing all owners of this vehicle to drive it despite the condition of that battery module. All I’m asking is for a part to be made. No one has managed to make a replacement or refurbished part but Mercedes who turned their backs on us. They were refurbishing the parts but stopped for some unknown reason. This is dangerous for all owners of the Mercedes SL chassis code r230. Please help you’re the only ones that can.
