The engine is equipped with the electronic engine control system, which monitors the engine
as it is running.
As soon as a fault is detected, it is evaluated and one of the following measures is initiated.
To prevent possible serious engine damage, have any faults
corrected without delay by an authorized dealer.
In conjunction with the ICU (instrumentation control unit), the code for the electronic
control unit reporting the fault can be read immediately on the display.
Complete fault codes are transmitted and can be read using minidiag2 at any authorized
dealer.
If the fault is serious enough to impair normal operation, the electronic engine system
switches over to emergency running mode. When in emergency running mode, the engine
operates at a constant 1300 rpm. This allows you to move the vehicle to a service location.
All information subject to change without notice.
