BMW 5 Series: Digital Motor Electronics (DME)

DME 8 control unit
The 8th generation engine electronics form a common control unit platform for
gasoline and diesel
engines that have been used since modular engines were introduced. Its
appearance is characterized
by a uniform housing and a uniform connector strip. The hardware inside has been
adapted to
the respective applications. The Bx8TU engines have the DME 8 engine electronics
generation.
Depending on the engine version, the Digital Motor Electronics (DME) will be
given a specific
designation.
DME 8.xTyz (x = number of cylinders, Ty = vehicle electrical system
architecture, z = H (hybrid)) can be
decoded as follows:
- DME 8.4T1 = B48
- DME 8.4T0.H = B48 PHEV
- DME 8.6T0 = B58
- DME 8.8T0 = N63

The lateral and longitudinal acceleration sensors assist with the
identification of head-on crashes,
side-on crashes and rear-end crashes.
The airbag sensor consists of a longitudinal acceleration sensor and a lateral
acceleration sensor.
