Check Engine Warning Light
The warning light in the instrument panel comes on
when the ignition is first turned on and remains on
briefly as a bulb check. If the light does not come
on, have the bulb replaced promptly.
If the warning lights in the instrument panel and
on-board computer come on and remain on while
driving, it suggests:
–
a potential engine control problem and the
need for system service
or
– an improperly fastened tank cap
or
– refueling with engine running.
Please observe the chapter ”WARNINGS
ON THE INSTRUMENT PANEL AND THE
ON-BOARD COMPUTER” on page 143.
Although the vehicle is usually driveable and will not
require towing, see your dealer for service as soon
as possible.
Caution!
If the Check engine light in the instrument
panel is  ashing, severe catalytic converter
damage and power loss will soon occur.
Prolonged driving with the Check engine
light on could cause damage to the emission
control system. It also could affect fuel
economy and driveability.
Have the fault remedied at the nearest
authorized Porsche dealer immediately.
