Cockpit Management and Data system - COMAND for short - acts as a combined command and control centre for all audio, telematics and telecommunications functions on Mercedes-Benz vehicles and includes a dedicated flat display screen. In addition to the GPS navigation system and general processing and control logic, COMAND includes components such as an address book, telephone, radio and in many cases a CD/DVD drive. It is connected to other (often separate) devices such as CD/DVD changers, sound system and surround sound amplifier, TV receiver and the optional Linguatronic voice control system via an optical fibre network. The first generations of COMAND used the D2B optical network standard whereas later models are based on MOST.
I think the first thing you need to do is confirm the RAC tech has provided you with a sound diagnosis as some models can take up to 10-12 mins to completely shut down, he may have been reading some consumers before the car had shut down completely. you could start off with a complete synopsis of the full details of your problem, I'm sure with a fuller picture members will be able to advise better.i have a battery drainage issue as in a 2 amp according to the RAC man has anyone had this on this model and is it common fault
moreover is it difficult to find ?
hi blobcat no water issues, now you saying the radio the day before i did have a problem with trying to switch it off must have took 5 or 6 times?Hello and welcome,
The "Comand" system is the satnav/radio big screen thing. They have a tendency to wake up and cause a battery drain.
You might have water issues in the boot which depending upon what devices are installed there can cause battery drain issues
