AirCon Compressor Shut Off Relay
The Motronic 1.7 and subfamilies, and the M3 and it’s variants are the next generation of BMW ECUs. The M1.7 was used on the M40, M42 and M70, the M1.7.1 was used solely for the S70, used in the BMW 850CSi. M1.7.2 was used for the M42 and M43 4 Cylinders. The M3.1 is a 6cyl ECU, used on the early M50 24v engines without VANOS. The M3.3 family were used to run the later 3.8 litre S38b38, the S50 3.0 M3, and the M60 V8s. M3.3.1 included VANOS control, and is used on M50 engines with VANOS, introduced to the E34 and E36 in 1992.

DME Control Unit -Self Test 1
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.

The MSS50 is a special ECU designed solely for the European E36 M3 3.2. Designed by Siemens, it integrates full Vanos control for both Intake and Exhaust Cams inside a single ECU, unlike the previous M3.3 which required a separate VNC Vanos Controller

AirCon Control Module
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

Fuel Injection Regulation
DDE 3 is the BMW name for the ECUs used on the M47 range on Diesel engines, also known as he Bosch EDC15. These are 4 Cylinder diesels, used in the E46 320d, and uses Common Rail Injection. Common Rail systems use a high pressure fuel rail with diesel injectors, as opposed to the mechanical injection systems, or the PD (Pumpe Düse) system where each injector also acts as a high pressure pump.
Outlet Valve – Rear Right
The first BMW ABS system, This was a 3 channel system, controlling braking to the front wheels,and a single line for both rear wheels. The wheel speed info could be passed via data lines to traction control systems, which could determine if the vehicle speed signal given from the rear driven axle did not match with the front wheel speed signals and request torque reduction intervention from the ASC (Anti Skid Control) throttle body.
