Check Engine (Emission Control)
Warning light
The emission control system detects malfunctions that could cause increased pollutant emissions or consequential damage etc. well in advance.

Faults are indicated by the warning light on the instrument panel which then either lights up continuously or flashes.

The faults are recorded in the control unit's fault memory.

The warning light on the instrument panel lights up when the ignition is switched on as a lamp check and goes out approx. 1 second after the engine starts.

The warning light on the instrument panel flashes to indicate operating states (e.g. engine misfiring) which may cause damage to certain parts of the emission control system.

  • In this case, immediately reduce the engine load by easing off the accelerator pedal.

In order to avoid consequential damage to the engine or the exhaust-gas cleaning system (e.g. catalytic converter):

  • Please contact an authorized Porsche dealer.


Risk of damage to the emission control system.

If the warning light on the instrument panel continues flashing even when you have eased off the accelerator pedal, the emission control system may overheat.

  • Stop as soon as possible in a safe place.
    Make sure that combustible materials, such as dry grass or leaves, cannot come into contact with the hot exhaust system.
  • Switch off the engine.
  • Have the fault corrected at an authorized Porsche dealer.

Acoustic Signals
A speaker in the instrument panel generates acoustic signals.

The warning message "Fault sound output instrument cluster – ParkAssist" will appear on the multi-function display in the instrument panel if a speaker fault occurs.

The speaker cannot generate acoustic signals.
