i drive a 2005 645ci , love the car. Recently i received several alert notifications on dash. one was for increased emmissions. my local bmw dealership checked it out .,smoked the system for leaks found no problems. a few days ago the light came back on was lit for 2 days and then went off. Today i started the car and a SOS/phone light went on and i could not receive calls through bluetooth and all calls dialed did not go through the bluetooth system. any suggestions thanx
