My 2004 530I would not start. They diagnosed the problem and installed a new starter, a new battery and also electronically synced the new battery with the electronic system. They also scanned the computer and found that the thermostat was stuck open, which meant in the winter the heater did not heat. That explains why my wife complained of being cold. Excellent service and a fun place to visit to see the old vehicles they are working towards making like new again.
