2006 w209. I just replaced the battery because the old one was at 5volts. Now the seat and wheel adjustments cannot be operated with the switches. But I can operate them thru STAR. Also the low beams will only come on with STAR. They also come on when I use the switch, but go out when I start the car. I have checked every fuse in the car. I have tried disconnecting and reconnecting the battery including letting it sit over night disconnected. Any assistance would be appreciated. Thanxs
