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. These are 4 Cylinder diesels, used in the E46 320d, and uses Common Rail Injection. DDE 3ĭDE 3 is the BMW name for the ECUs used on the M47 range on Diesel engines, also known as he Bosch EDC15. This system was used on the M51TU engines. This is an Updated version of the previous DDE 2.1, and was introduced in 1995. DDE 2.1 uses an updated Air Mass Meter with an Internal Air Temperature Sensor, whilst DDE2 has a separate sensor in the manifold. DDE 2 and DDE 2.1ĭDE stands for Digital Diesel Electronics, and these were used on BMW’s Diesel engines. It also found its way into a few rare Lincoln Continentals.

The first series of Diesel engines used the DDE1 control unit, and was found in the M21 powered E30 324d and td, and the E28 524d and 524td. Valvetronic removes the need for a throttle butterfly, passing air control directly onto fully controlable valves. DME 9ĭME 9 or ME9 is used on Valvetronic BMW engines. It uses Torque modeling to control the engine torque output depending on Throttle Pedal Position. 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. The Bosch BMS46 is a Hybrid ECU, created from a joint effort with Siemens, and is used in later M43 engines used in the Z3 and E46 series. The system uses an Electronic Throttle to accurately control Air intake instead of the more common Cable throttles used on earlier vehicles DME M5.2 and M5.2.1ĭME M5.2 and M5.2.1 are Bosch ECUs, used on the M44 4cyl engine, and the M62 V8, and the M72 V12 BMS43 and BMS46 The MSS54 is used on the E46 M3 and on some Z3Ms. The MSS52 is an M Power ECU designed to run the E39 M5, the Z8 Roadster, and also the Wiesmann Roadsters. 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 MSS52 and MSS54 The MSS50 is a special ECU designed solely for the European E36 M3 3.2. The OBD2 P codes fault protocol was not activated in European markets on this group, as currently it was not required by law. The MS41 was used on the M52 series of engines, MS42 on the M52TU series, and MS43 on the M43 4 Cylinders. This includes Catalytic Converter monitoring and Long / Short term Fueling and Ignition Adaptation. The next generation Siemens MS ECUs introduced many of the OBD2 features. MS40.0 is a rare ECU used on non VANOS 2.0l, and MS40.1 introduced VANOS control. BMW split the M50 24v engines and used Siemens for some of the 2.0 litres, and Bosch continued on with the 2.5l. MS40 was a new ECU for BMW, manufactured by Siemens instead of the previous Bosch Motronics.
M3.3.1 included VANOS control, and is used on M50 engines with VANOS, introduced to the E34 and E36 in 1992. The M3.3 family were used to run the later 3.8 litre S38b38, the S50 3.0 M3, and the M60 V8s. 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. Was used solely for the S70, used in the BMW 850CSi. The M1.7 was used on the M40, M42 and M70, the M1.7.1 The Motronic 1.7 and subfamilies, and the M3 and it’s variants are the next generation of BMW ECUs. M1.1 and M1.3 was used on the M20, M30 and M40 engines, whilst M1.2 was used on the S38 and M70, which are the early E34 M5 engines and the early V12s. The BMW DME M1.1 (and similar, 1.2 and 1.3) is an early Bosch Motronic ECU, used on all of the 6 Cylinder BMWs up until 1990, and a few more after that. To search for your code, follow the list below, or press ctrl+f to search within this page.Īll codes from DDE4 onwards are listed as the HEX value. Hex format is a hexadecimal number, used by computers to count in base 16, so there are 16 numbers before “10”, instead of our ten.

The code reader or diagnostic tool will ask the module for any stored codes, and it will receive a number in hex format. If you don’t recognize the codes, this list will help you. If you are reading codes from specific BMW modules, you may find you get a code. Most of BMW diagnostic softwares like DIS, INPA, EDIABAS, IBUS, CANBUS, CARSOFT, give an error code but no or limited explanation.
