The car kept shaking till I took the next exit. It was very dangerous as I entered the highway with that speed and there was a bunch of cars going at least 75 mls/hr that had to leave the lane I'm on. Darn it. The engine light is on now. I parked the car and I'm at work now. WTF!!  |

Im one step away from filing a lemon law suit for it.

Same problem we had on a colleague's car. We took it to various BMW and all followed the procedure by replacing everything then at our desperate call to the leasing company they suggested another dealer who immediately said that the problem was by the thermostat. It is common for the BMW's that the thermostat during the winter stacks and doesn't allow the systems to understand how to operate properly the engine. It is also the reason that the computer cannot record any problem.
