got a fault code today on my 11 e92 335 w cobb APV-3, CP and bmw exhaust. If you are reading codes from specific BMW modules, you may find you get a code DDE stands for Digital Diesel Electronics, and these were used on BMWs Diesel engines. The code reader or diagnostic tool will ask the module for any stored codes, and it will receive a number in hex format. 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 gear symbol is the general fault message from the SMG and can have many different causes. BMW & MINI Engine Technical Data Dragon Automotive have pieced together a comprhensive list of BMW engines and their production dates using our knowledge and that from Wikipedia. Example: P1055 Hex Codes are typically given by more advanced scanners. Designed by CSS WebSystems. The MSS50 is a special ECU designed solely for the European E36 M3 3.2. Scan code: Fault location: Probable cause - Engine control module (ECM) -data exchange not possible: Wiring between DLC and ECM, supply voltage, engine control relay, DLC: 0: Engine control module (ECM) - undefined fault: Disconnect ECM multi-plug for at least 10 min.- check if trouble code reappears before replacing ECM: 1 This includes CatalyticConverter monitoring and Long / Short term Fueling and Ignition Adaptation. Full Forum Listing. BMW Engines XXX Engines Listed List of BMW Engines MINI Engines BMW Fault Codes (DTCs) Below is a comprehensive listing of BMW DTCs and the corresponding SAE P-codes. 1282 Fault Code Memory: This code occurs when the DME generates a set of conflicting codes.
