Check and regulation of a corner of Zuvorkommens of ignition

As the corner of Zuvorkommens of ignition is constantly controlled and the motor is adjusted by tax system, face value does not exist. Check and manual regulation is impossible.

The corner can be checked by means of the special equipment which communicates in the diagnostic plug of tax system the motor (You banish the car on 100 Mercedes Benz).

Regulation is impossible.

If the corner is defined mistakenly, it is tax system the motor incorrectly.
