Engine Management for the Phaeton W12 Engine – Self-Study Programme 250 PDF. This Self-Study Programme will familiarise you with the ME7.1.1 engine management system, the interaction between the two control units, the sensors, the actuators and individual subsystems.
The Motronic engine management system for the W12 engine allows high engine performance with low fuel consumption by adapting to all operating conditions. At the heart of the Motronic ME7.1.1 are two electronic control units.
In contrast with the W8 engine, what is known as a two-control unit concept is used in the W12 engine. This concept regards the two cylinder banks as two separate engines. Essentially, each control unit is assigned to just one bank.
Control unit 2 obtains information that has been entered only into Control unit 1 via the internal CAN databus. This internal CAN databus serves exclusively to exchange information between the engine control units.
This SSP 250 is based on the information in SSP 248 “The W Engine Concept“
The Self-Study Programme presents the design and function of new developments.
Please always refer to the relevant Service Literature for all current inspection, adjustment and repair instructions.
