The 750il v12 engine is really like two siamesed inline sixes. Engine management of the left and right banks is done independently. So, what sounds like happened to your car is something in the engine management system failed on one side. Congratulations, you're now driving a 2.5l six cylinder! I would invest in a code reader from www.peakeresearch.com ($150), which should help you pinpoint the component that blew.

This car was BMW's first "drive-by-wire" car, which means that their is no throttle cable - just sensors and motors to operate the throttle butterfly. I hear these fail fairly often (at least too often for a $400 component).



Several Weeks ago I lost power ans assumed that it was either the fuel pumps and or fuel pressure regulators. I have replaced all componebts at this time. I also checked the relays by interchanging them to the working side. At this point, I am thinking something electrical. Also, when this intially happen, I did see a little smoke coming in on the passenger side with the smell of something electricl burning. I notoce that the passenger side of the engine seems cold to the touch. Morover, the car has little power and will cut off from time to time. Any ideas? also the fuel filters were replaced a month and a half ago. Any ideas?
