Throttle Valve Final Stage
The next generation Siemens MS ECUs introduced many of the OBD2 features. This includes Catalytic Converter monitoring and Long / Short term Fueling and Ignition Adaptation. The MS41 was used on the M52 series of engines, MS42 on the M52TU series, and MS43 on the M43 4 Cylinders.
The OBD2 P codes fault protocol was not activated in European markets on this group, as currently it was not required by law.

Exhaust VANOS Bank 2 Function
The MSS52 is an M Power ECU designed to run the E39 M5, the Z8 Roadster, and also the Wiesmann Roadsters. The MSS54 is used on the E46 M3 and on some Z3Ms. The system uses an Electronic Throttle to accurately control Air intake instead of the more common Cable throttles used on earlier vehicles

Camshaft Position Sensor Bank 2
The Bosch DME 7.2, also known as ME7.2, can be found on a number of V8 Petrol engines, used in the 5 and 7 Series amongst others. It uses Torque modeling to control the engine torque output depending on Throttle Pedal Position.
CAN Error – Instrument Cluster
This is an Updated version of the previous DDE 2.1, and was introduced in 1995. This system was used on the M51TU engines.
Speed Information Front Right
The updated version of BMW’s ABS system, this was more advanced. Improvements include a 4 channel system for independent rear wheel braking, which allowed a more active ASC system. With individual braking, not only could a torque reduction be requested via the ASC secondary throttle body, but independent wheel braking could be used to control individual wheel slip as part of a stability program.
