The original multi-displacement system turned off opposite pairs of cylinders, allowing the engine to have three different configurations and displacements. C0582 code had an elaborate diagnostics procedure, including showing engine trouble codes on the air conditionning display. However, the system was troublesome, misunderstood by customers, and a rash of unpredictable failures led to the technology being quickly retired.

  • EVAP canister or fuel tank leaks
  • Faulty Intake Valve Timing Control Solenoid Valve
  • Faulty TCM or TCM programming
  • Variable Valve Timing (VVT) circuit is open or shorted

Gear changes are accomplished by a command from the BMW TCM to energize the clutch actuator to release the clutch; after which various actuators inside the transmission disengage the current gear, and depending on current operating conditions, engage the next higher or lower gear ratio. All of this happens much faster than a human driver could change gears, and in most applications, gear changes are as smooth and seamless as on any fully automatic transmission.
