Version 2.0
Please read these WARNINGS and CAUTIONS before proceeding with maintenance and
repair work. You must answer that you have read and you understand these WARNINGS and
CAUTIONS before you will be allowed to view this information.
If you lack the skills, tools and equipment, or a suitable workshop for any procedure described
in this manual, we suggest you leave such repairs to an authorized Audi retailer or other
qualified shop. We especially urge you to consult an authorized Audi retailer before beginning
repairs on any vehicle that may still be covered wholly or in part by any of the extensive
warranties issued by Audi.
Disconnect the battery negative terminal (ground strap) whenever you work on the fuel system
or the electrical system. Do not smoke or work near heaters or other fire hazards. Keep an
approved fire extinguisher handy.
Audi is constantly improving its vehicles and sometimes these changes, both in parts and
specifications, are made applicable to earlier models. Therefore, part numbers listed in this
manual are for reference only. Always check with your authorized Audi retailer parts
department for the latest information.
Any time the battery has been disconnected on an automatic transmission vehicle, it will be
necessary to reestablish Transmission Control Module (TCM) basic settings using the Audi
Factory Approved Scan Tool (ST).
Never work under a lifted vehicle unless it is solidly supported on stands designed for the
purpose. Do not support a vehicle on cinder blocks, hollow tiles or other props that may
crumble under continuous load. Never work under a vehicle that is supported solely by a jack.
Never work under the vehicle while the engine is running.
For vehicles equipped with an anti-theft radio, be sure of the correct radio activation code
before disconnecting the battery or removing the radio. If the wrong code is entered when the
power is restored, the radio may lock up and become inoperable, even if the correct code is
used in a later attempt.
If you are going to work under a vehicle on the ground, make sure that the ground is level.
Block the wheels to keep the vehicle from rolling. Disconnect the battery negative terminal
(ground strap) to prevent others from starting the vehicle while you are under it.
Do not attempt to work on your vehicle if you do not feel well. You increase the danger of
injury to yourself and others if you are tired, upset or have taken medicine or any other
substances that may impair you or keep you from being fully alert.
Never run the engine unless the work area is well ventilated. Carbon monoxide (CO) kills.
Always observe good workshop practices. Wear goggles when you operate machine tools or
work with acid. Wear goggles, gloves and other protective clothing whenever the job requires
working with harmful substances.
Tie long hair behind your head. Do not wear a necktie, a scarf, loose clothing, or a necklace
when you work near machine tools or running engines. If your hair, clothing, or jewelry were to
get caught in the machinery, severe injury could result.

Version 2.0
Do not re-use any fasteners that are worn or deformed in normal use. Some fasteners are
designed to be used only once and are unreliable and may fail if used a second time. This
includes, but is not limited to, nuts, bolts, washers, circlips and cotter pins. Always follow the
recommendations in this manual - replace these fasteners with new parts where indicated,
and any other time it is deemed necessary by inspection.
Illuminate the work area adequately but safely. Use a portable safety light for working inside or
under the vehicle. Make sure the bulb is enclosed by a wire cage. The hot filament of an
accidentally broken bulb can ignite spilled fuel or oil.
Friction materials such as brake pads and clutch discs may contain asbestos fibers. Do not
create dust by grinding, sanding, or by cleaning with compressed air. Avoid breathing
asbestos fibers and asbestos dust. Breathing asbestos can cause serious diseases such as
asbestosis or cancer, and may result in death.
Finger rings should be removed so that they cannot cause electrical shorts, get caught in
running machinery, or be crushed by heavy parts.
Before starting a job, make certain that you have all the necessary tools and parts on hand.
Read all the instructions thoroughly, do not attempt shortcuts. Use tools that are appropriate to
the work and use only replacement parts meeting Audi specifications. Makeshift tools, parts
and procedures will not make good repairs.
Catch draining fuel, oil or brake fluid in suitable containers. Do not use empty food or
beverage containers that might mislead someone into drinking from them. Store flammable
fluids away from fire hazards. Wipe up spills at once, but do not store the oily rags, which can
ignite and burn spontaneously.
Use pneumatic and electric tools only to loosen threaded parts and fasteners. Never use these
tools to tighten fasteners, especially on light alloy parts. Always use a torque wrench to tighten
fasteners to the tightening torque listed.
Keep sparks, lighted matches, and open flame away from the top of the battery. If escaping
hydrogen gas is ignited, it will ignite gas trapped in the cells and cause the battery to explode.
Be mindful of the environment and ecology. Before you drain the crankcase, find out the
proper way to dispose of the oil. Do not pour oil onto the ground, down a drain, or into a
stream, pond, or lake. Consult local ordinances that govern the disposal of wastes.
The air-conditioning (A/C) system is filled with a chemical refrigerant that is hazardous. The
A/C system should be serviced only by trained automotive service technicians using approved
refrigerant recovery/recycling equipment, trained in related safety precautions, and familiar
with regulations governing the discharging and disposal of automotive chemical refrigerants.
Before doing any electrical welding on vehicles equipped with anti-lock brakes (ABS),
disconnect the battery negative terminal (ground strap) and the ABS control module
connector.
Do not expose any part of the A/C system to high temperatures such as open flame.
Excessive heat will increase system pressure and may cause the system to burst.

Version 2.0
When boost-charging the battery, first remove the fuses for the Engine Control Module (ECM),
the Transmission Control Module (TCM), the ABS control module, and the trip computer. In
cases where one or more of these components is not separately fused, disconnect the control
module connector(s).
Some of the vehicles covered by this manual are equipped with a supplemental restraint
system (SRS), that automatically deploys an airbag in the event of a frontal impact. The airbag
is operated by an explosive device. Handled improperly or without adequate safeguards, it can
be accidentally activated and cause serious personal injury. To guard against personal injury
or airbag system failure, only trained Audi Service technicians should test, disassemble or
service the airbag system.
Do not quick-charge the battery (for boost starting) for longer than one minute, and do not
exceed 16.5 volts at the battery with the boosting cables attached. Wait at least one minute
before boosting the battery a second time.
Never use a test light to conduct electrical tests of the airbag system. The system must only
be tested by trained Audi Service technicians using the Audi Factory Approved Scan Tool (ST)
or an approved equivalent. The airbag unit must never be electrically tested while it is not
installed in the vehicle.
Some aerosol tire inflators are highly flammable. Be extremely cautious when repairing a tire
that may have been inflated using an aerosol tire inflator. Keep sparks, open flame or other
sources of ignition away from the tire repair area. Inflate and deflate the tire at least four times
before breaking the bead from the rim. Completely remove the tire from the rim before
attempting any repair.
When driving or riding in an airbag-equipped vehicle, never hold test equipment in your hands
or lap while the vehicle is in motion. Objects between you and the airbag can increase the risk
of injury in an accident.

Version 2.0
Please read these WARNINGS and CAUTIONS before proceeding with maintenance and
repair work. You must answer that you have read and you understand these WARNINGS and
CAUTIONS before you will be allowed to view this information.
If you lack the skills, tools and equipment, or a suitable workshop for any procedure described
in this manual, we suggest you leave such repairs to an authorized Audi retailer or other
qualified shop. We especially urge you to consult an authorized Audi retailer before beginning
repairs on any vehicle that may still be covered wholly or in part by any of the extensive
warranties issued by Audi.
Disconnect the battery negative terminal (ground strap) whenever you work on the fuel system
or the electrical system. Do not smoke or work near heaters or other fire hazards. Keep an
approved fire extinguisher handy.
Audi is constantly improving its vehicles and sometimes these changes, both in parts and
specifications, are made applicable to earlier models. Therefore, part numbers listed in this
manual are for reference only. Always check with your authorized Audi retailer parts
department for the latest information.
Any time the battery has been disconnected on an automatic transmission vehicle, it will be
necessary to reestablish Transmission Control Module (TCM) basic settings using the Audi
Factory Approved Scan Tool (ST).
Never work under a lifted vehicle unless it is solidly supported on stands designed for the
purpose. Do not support a vehicle on cinder blocks, hollow tiles or other props that may
crumble under continuous load. Never work under a vehicle that is supported solely by a jack.
Never work under the vehicle while the engine is running.
For vehicles equipped with an anti-theft radio, be sure of the correct radio activation code
before disconnecting the battery or removing the radio. If the wrong code is entered when the
power is restored, the radio may lock up and become inoperable, even if the correct code is
used in a later attempt.
If you are going to work under a vehicle on the ground, make sure that the ground is level.
Block the wheels to keep the vehicle from rolling. Disconnect the battery negative terminal
(ground strap) to prevent others from starting the vehicle while you are under it.
Do not attempt to work on your vehicle if you do not feel well. You increase the danger of
injury to yourself and others if you are tired, upset or have taken medicine or any other
substances that may impair you or keep you from being fully alert.
Never run the engine unless the work area is well ventilated. Carbon monoxide (CO) kills.
Always observe good workshop practices. Wear goggles when you operate machine tools or
work with acid. Wear goggles, gloves and other protective clothing whenever the job requires
working with harmful substances.
Tie long hair behind your head. Do not wear a necktie, a scarf, loose clothing, or a necklace
when you work near machine tools or running engines. If your hair, clothing, or jewelry were to
get caught in the machinery, severe injury could result.

Version 2.0
Do not re-use any fasteners that are worn or deformed in normal use. Some fasteners are
designed to be used only once and are unreliable and may fail if used a second time. This
includes, but is not limited to, nuts, bolts, washers, circlips and cotter pins. Always follow the
recommendations in this manual - replace these fasteners with new parts where indicated,
and any other time it is deemed necessary by inspection.
Illuminate the work area adequately but safely. Use a portable safety light for working inside or
under the vehicle. Make sure the bulb is enclosed by a wire cage. The hot filament of an
accidentally broken bulb can ignite spilled fuel or oil.
Friction materials such as brake pads and clutch discs may contain asbestos fibers. Do not
create dust by grinding, sanding, or by cleaning with compressed air. Avoid breathing
asbestos fibers and asbestos dust. Breathing asbestos can cause serious diseases such as
asbestosis or cancer, and may result in death.
Finger rings should be removed so that they cannot cause electrical shorts, get caught in
running machinery, or be crushed by heavy parts.
Before starting a job, make certain that you have all the necessary tools and parts on hand.
Read all the instructions thoroughly, do not attempt shortcuts. Use tools that are appropriate to
the work and use only replacement parts meeting Audi specifications. Makeshift tools, parts
and procedures will not make good repairs.
Catch draining fuel, oil or brake fluid in suitable containers. Do not use empty food or
beverage containers that might mislead someone into drinking from them. Store flammable
fluids away from fire hazards. Wipe up spills at once, but do not store the oily rags, which can
ignite and burn spontaneously.
Use pneumatic and electric tools only to loosen threaded parts and fasteners. Never use these
tools to tighten fasteners, especially on light alloy parts. Always use a torque wrench to tighten
fasteners to the tightening torque listed.
Keep sparks, lighted matches, and open flame away from the top of the battery. If escaping
hydrogen gas is ignited, it will ignite gas trapped in the cells and cause the battery to explode.
Be mindful of the environment and ecology. Before you drain the crankcase, find out the
proper way to dispose of the oil. Do not pour oil onto the ground, down a drain, or into a
stream, pond, or lake. Consult local ordinances that govern the disposal of wastes.
The air-conditioning (A/C) system is filled with a chemical refrigerant that is hazardous. The
A/C system should be serviced only by trained automotive service technicians using approved
refrigerant recovery/recycling equipment, trained in related safety precautions, and familiar
with regulations governing the discharging and disposal of automotive chemical refrigerants.
Before doing any electrical welding on vehicles equipped with anti-lock brakes (ABS),
disconnect the battery negative terminal (ground strap) and the ABS control module
connector.
Do not expose any part of the A/C system to high temperatures such as open flame.
Excessive heat will increase system pressure and may cause the system to burst.

Version 2.0
When boost-charging the battery, first remove the fuses for the Engine Control Module (ECM),
the Transmission Control Module (TCM), the ABS control module, and the trip computer. In
cases where one or more of these components is not separately fused, disconnect the control
module connector(s).
Some of the vehicles covered by this manual are equipped with a supplemental restraint
system (SRS), that automatically deploys an airbag in the event of a frontal impact. The airbag
is operated by an explosive device. Handled improperly or without adequate safeguards, it can
be accidentally activated and cause serious personal injury. To guard against personal injury
or airbag system failure, only trained Audi Service technicians should test, disassemble or
service the airbag system.
Do not quick-charge the battery (for boost starting) for longer than one minute, and do not
exceed 16.5 volts at the battery with the boosting cables attached. Wait at least one minute
before boosting the battery a second time.
Never use a test light to conduct electrical tests of the airbag system. The system must only
be tested by trained Audi Service technicians using the Audi Factory Approved Scan Tool (ST)
or an approved equivalent. The airbag unit must never be electrically tested while it is not
installed in the vehicle.
Some aerosol tire inflators are highly flammable. Be extremely cautious when repairing a tire
that may have been inflated using an aerosol tire inflator. Keep sparks, open flame or other
sources of ignition away from the tire repair area. Inflate and deflate the tire at least four times
before breaking the bead from the rim. Completely remove the tire from the rim before
attempting any repair.
When driving or riding in an airbag-equipped vehicle, never hold test equipment in your hands
or lap while the vehicle is in motion. Objects between you and the airbag can increase the risk
of injury in an accident.
