Control indicator A for engine electronics
Illuminates for a few seconds after the
ignition is switched on.
If it illuminates when the engine is running,
there is a fault in engine or transmission
electronics. The electronic system switches
to an emergency running programme. Fuel
consumption may be increased and the
driveability of the vehicle may be impaired.
In some cases, faults can be eliminated by
switching off the engine and restarting. If
the control indicator comes on again when
the engine is running, contact a workshop
to eliminate the cause of the fault.
If it illum ina tes briefly , but does not recur, it
is of no significance.
Illumination of A can indicate wa te r in the
diesel fuel filter 3, at the same time a
message appears in the service display,
see page 120. Have a workshop check the
fuel filter for possible water residue.
If it flashes after the ignition is switched on,
there is a fault in the immobiliser system.
The engine cannot be started – see
page 29.
