2009 AUDI S3 catalytic converter

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 Diagnostic system (08D)
On-Board Diagnostics
Fig. 10 location of
Data Link Connecto r
( DL C)
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=>
page 21, fig. 10 .
Your authorized Audi dealer or a qualified service station can inter ­
pret the code and perform the necessary repair. •
Contro ls and eq uip­
ment
Driver information display
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. _.,

New brake pads
--
Remember that new brake pads do not have a full braking
effect during the first 250 miles (400 kilometers) after they
are installed .
New brake pads have to be "burnished in" before they have optimal
grab =>& .
During the break -in period, you should avoid putting severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very high speeds or, for example, on moun­
tain passes.
& WARNING
Until they develop the maximum "bite " for best stopping power,
the surfaces on new brake pads require some "breaking -in" during
the initial 100 to 150 miles (150 to 200 kilometers) of normal city
driving. You can compensate for this by pressing the brake pedal
more firmly . This applies whenever new pads are installed.•
Catalytic converter
It is very important that your emission control system
(catalytic converter) is functioning properly to ensure that
your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline:=> page 219, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ==>
page 230,
"Adding engine oil 't=:;rl".
Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle. The catalytic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire .
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance used for undercoating
could overheat and cause a fire .
0 Note
• Be aware that just one tank filling with leaded fuel will alr eady
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level=>
page 230.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emission Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. •

The engine and catalytic converter have to reach their optimal ope r­
at ing t emp era tur e
to reduce fuel consumption and noxious emis ­
sions effectively .
• Just after starting, a cold engine in a mid -size car burns the fuel
at a poor rate of 6-8 miles per gal lon (30-40 11100km). Half a mile
down the road, the mileage improves to 12 MPG (201/100 km). It will
take the eng ine no less than
two and a half miles (4 km) of driv ing to
warm up to its proper operating temperature and operate at an
economic mileage. This explains why taking the car for short trips is
a rather wasteful convenience.
• The
out sid e tem perature is also critical in th is regard . Your car
consumes more fuel in the winter than in the summer.

Fuel supply and filling your fuel tank
Gasoline
Fuel supply Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel r ecomm end ati on
The fuel recommended for your vehic le is unl eade d prem ium grade
gaso line . See also ~
page 300, "Data". Audi recommends using TOP
T IER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gaso line, please
go to the official website (www.toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the inside of the fuel fille r flap. This
rating may be specified as AK I or RON .
Your vehic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON . However, using 87
AKl/9 1 RON octane fuel will slightly reduce engine performance.
Use unle ad ed ga so line only . Unleaded gaso line is avai lable
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countr ies
where un leaded gasoline may not be available .
For more information on refueling your vehicle, see~
page 220.
Octane ra tin g
Octane rating indicates a gaso line's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
Therefore, buying the correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance.
F ue l supply and fillin g you r fu el tank
Gasoline most common ly used in the United States and Canada has
the following octane ratings that can usua lly be found on the filler
pump:
• Premium Grade : 91 -96 AKI
• Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R +M)/2 = (RON +MON)/2
RON = Research Octane Number
MON
= M otor Octane Number .
0 Note
• Do not use any fue l with octane ratings lower than 87 AKI or 91
RON otherwise expensive engine damage will occur .
• Do
not use leaded gasoline! The use of leaded gasoline will
severe ly damage your vehicle's catalytic converter and its abi lity to
control exhaust emissions. •
Blended gasoline
Use of g aso line containing alco hol or M TB E ( meth yl
t er tiary butyl e ther )
You may use unleaded gasoline blended with alcohol or MTBE
(commonly referred to as oxygenates) if the blended mixture meets
the follow ing criteria:
Bl end of g asoline m eth anol (wood al coho l or methyl alc oh ol)
• Anti-knock index must be 87 AKI or higher .
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.
