Hi. A lot of topics on this matter, but none that could give me a definitive answer. Basically I picked up an E55k yesterday, and whenever I would like to use the SBC Hold feature, it comes with the SBC Hold unavailable. From what I found, it may be a switch at the gear lever, that is not giving the correct signal of its position? What would be the cost in repairing it if someone has had the some problem here? However, is there also a possibility that this error comes up when the break switch is not working properly? Hopes are not high tough, as I know when the brake switch is faulty, it will disable the ESP and Cruise Control as well. Also, the SBC tends to vibrate and sound noisy for a couple of seconds at lower speeds. I read that it is normal and a damper should fix this, but if I leave it as it is, there won't be any harm, will it? Thanks for any help.
