Possible cause/consequence
There is a malfunction in:
The fuel management system
The ignition system
The emission control system
Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the en-
gine to its limp-home (emergency

Suggested solution

sible by an authorized Mercedes-Benz
Center.
An on-board diagnostic connector is used
by the service station to link the vehicle to
the shop diagnostics system. It allows the
accurate identification of system malfunc-
tions through the readout of diagnostic
trouble codes. It is located in the front left
area of the footwell next to the parking
brake pedal.
