27Da Fault Code E83 Code But No

Most of BMW diagnostic softwares like DIS, INPA, EDIABAS, IBUS, CANBUS, CARSOFT, give an error code but no or limited explanation.

The code reader or diagnostic tool will ask the module for any stored codes, and it will receive a number in hex format.

The extra numbers are A,B,C,D,E and F.

A,B,C,D,E,F,10, but Hexs 10 is Decimals 15.

BMW split the M50 24v engines and used Siemens for some of the 2.0 litres, and Bosch continued on with the 2.5l.

This includes Catalytic Converter monitoring and Long Short term Fueling and Ignition Adaptation.

27Da Fault Code E83 Series Of Engines

The MS41 was used on the M52 series of engines, MS42 on the M52TU series, and MS43 on the M43 4 Cylinders.

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.

It uses Torque modeling to control the engine torque output depending on Throttle Pedal Position.

Valvetronic removes the need for a throttle butterfly, passing air control directly onto fully controlable valves.

DDE2 is used on M41 and M51 engines.

DDE 2.1 uses an updated Air Mass Meter with an Internal Air Temperature Sensor, whilst DDE2 has a separate sensor in the manifold.

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 Dse) system where each injector also acts as a high pressure pump.

DDE4 is seen in the M57 range of 6 Cylinder engines, from 2.5 to 3.0l displacement, and the DDE4.1 was used in a twin Master Slave arrangement in the M67 V8 diesels, with each ECU controlling one bank of the engine.

DDE 6 is used on M57 and M67 engines from 2005, using the same 1600 bar Common Rail System, and now meeting the European EU4 emissions standard.

The wheel speed info could be passed via data lines to traction control systems, which could.
