2009 AUDI S3 check engine light

If the engine RPMs drop below 1 500, you should downshift to the
next lower gear. The red area at the end of the scale indicates
maximum permissible engine RPMs after the break-in period.
Before reaching this area, you should either shift into the next
higher gear or ease your foot off the accelerator pedal .
0 Note
The tachometer needle=> page 8, fig. 2 G) should not move into the
red range. If it does, then only for a very short period of time. You
could damage your engine by driving at high RPM!
<£> For the sake of the environment
Upshifting early saves fuels and reduces engine noise. •

Engine coolant temperature gauge
The engine coolant gauge 0 => page 8, fig. 2 only works when the
ignition is on. To prevent damage to your engine, please note the
following important points:
~
Vehicle care I I irechnical data

Instruments and warning/indicator lights
Engine cold
As long as the needle remains at the left end of the gauge, the
engine still has not reached its operating temperature . Avoid high
engine speeds, heavy engine loads and heavy throttle.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the middle of the gauge and remain there. If the engine is working hard at high outside temperatures, the needle
may turn further to the right. This is no cause for concern as long as
the
_ f_ warning light in the instrument cluster does not illuminate.
When the
-L warning light starts to flash, this can mean one of two
things: either the coolant
temperature is too high, or the coolant
level is too low=> page 30.
& WARNING
• Always observe the warning in => page 217, "Engine compart ­
ment" before opening the engine hood and checking the engine
coolant level.
• Never open the engine hood if you see or hear steam, or if you
see engine coolant dripping from the engine compartment. You
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant.
0 Note
• Mounting additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator . At high outside tempera ­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle is moving. If the spoiler is damaged,
this could reduce the cooling effect and the engine could then over ­
heat. Ask your authorized Audi dealer for assistance. •
Fuel gauge
The fuel gauge works only when the ignition is on.
When the needle reaches the red area, the warning light in the
instrument cluster will illuminate=>
page 32 I). This means you
have approximately 1.8 gallons (7 liters) of fuel left in the tank.
Time
to refuel!
The total tank capacity of your vehicle is listed in=> page 300,
"Data".
0 Note
Never run the tank completely dry! An irregular supply of fuel can
cause engine misfiring and fuel could enter into the exhaust
system. The catalytic converter could then overheat and be
damaged .•
Speedometer with odometer
The speedometer shows you the vehicle speed, and the
odometer shows you how many miles (kilometers) you
have driven.

On-Board Diagnostics monitors the components of your emission
control system . Each controlled component in your engine system
has been assigned a code. In case of a malfunction , the component
will be identified and the fault stored as a code in the control
module memory .
The Mil lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system . If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed=>
page 227.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the engine hood re lease lever=>

Malfunction Indicator Lamp (MIL) (USA
models)/ (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 17, fig . 5 is part of the On-Board Diagnostic (OBD II) system .
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabilized. This indicates that the Mil is working properly .
If the light does not go out after the engine is started, or illuminates
while you are driving, a ma lfunction may exist in the engine system.
If the light starts flashing, the catalytic converter cou ld be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected . Contact your authorized Audi dealer.
If the light illuminates , the electronic speed limiter may also be
malfunctioning. For more information=>
page 27, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate => page 221. •
Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, yo ur vehicle also has an electronic speed limiter. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information
=> page 257, "Speed rating
(letter code)".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfun cti on Indicator Light (MIU will illuminate . If this
occurs, contact the nearest authori zed Audi dealer for assistance. _.,

-Turn off the engine.
- Check coolant level => page
233 .
-Add coolant if necessary => page 234 .
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
=> page 14, then the fan belt may be damaged .
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 58, "Emer­
gency flasher
A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn off
the engine and allow it to cool . Follow the warning stickers
=> page 217, "Engine compartment" .
