I have a MY1999 S500 which is bloomin' marvellous, but she does have one idiosyncracy which I'd like to resolve.
She is quite a high spec car and cost someone a lot of money when she was new. Everything on her works most of the time, but there are occasions when the Comand system becomes temperamental. What happens is, the system will be working fine, then with a slight crackle through the speakers the sound will go. Generally at the same time the system will suddenly decide it doesn't have a CD player or a phone, but it does still have a tape player, a radio, and a nav system. In other words the head unit has lost communication with the other units in the car, including the amplifier. I have had the head unit overhauled and I don't believe it is the culprit; it communicates with the dash display whatever is happening and seems to be doing what it should. I suspect there is either a wiring problem in the car and/or there is a central computer/switching device somewhere which needs overhauling or replacing. Before I give up and take it to the dealer does anyone have previous experience of this type of problem and if so can you give me a clue as to where I might focus my efforts to fix this? All suggestions gratefully received.
