Audi Q3: General, Technical data
Safety Precautions
Start/Stop System Safety Precautions
When Working on Vehicles with the Start/Stop System, Observe
the Following:
WARNING
Danger of personal injury because the engine can
start automatically on vehicles with Stop/Start.
- When the Start/Stop System is activated (the
indicator lamp in the instrument cluster is on), the
engine can start up automatically.
- Always make sure the Start/Stop System is
deactivated whenever working on the vehicle. Switch off
the ignition.
Road Test with Testing Equipment Safety Precautions
If Measuring Equipment are Required During a Test Drive,
Observe the Following:
WARNING
Distraction and inadequately secured measuring
equipment poses an accident risk.
There is a risk due to deployment of the front
passenger airbag in an accident.
- Operating measuring equipment while driving creates
a distraction.
- There is an increased risk of injury if measuring
equipment is not secured.
Always secure measuring equipment with a strap on
the rear seat and have a second person in the rear seat
operate it.
HID Headlamp Usage and Safety Precautions
Never Replace Bulbs if You Are Not Familiar with the
Procedures, Safety Precautions and Tools.
WARNING
Danger to life due to high voltage.
- For work on the yellow high voltage symbol marked
areas HID headlamp must be de-energized.
- Turn off the ignition and all electrical consumers
and remove the ignition key.
- Do not press the flasher.
- The gas discharge lamp control module should not be
operated without the gas-discharge lamp.
- Due to the high voltage (over 28000 V when igniting
the lamp), the gas-discharge lamp should only be
operated inside the headlamp housing.
WARNING
Risk of injury due to burning, UV rays, blinding and
explosion.
- Due the high temperatures, absorption of UV rays,
and the risk of blinding, the gas discharge lamp should
only be operated inside the headlamp housing.
- Do not look into the beam of light. It may interfere
with the ability to see for a significant period of
time.
- Gas-discharge lamps are under pressure and can crack
when bulbs are replaced.
- When removing and installing HID bulbs, always wear
safety glasses and gloves.
WARNING
Pollution risk.
- Gas-discharge bulbs require special disposal. They
contain metallic mercury (Hg) and traces of thallium.
- Do not destroy gas-discharge lamps. Avoid contact
with burst glass bulbs.
- Follow disposal requirements, only dispose of
gas-discharge lamps in suitable containers at an
authorized collection site.
Caution
- Do not touch gas-discharge bulbs with bare hands.
The remaining fingerprint would evaporate due to the
heat of the operated bulb and condense on the reflector
which would impair headlamp luminosity. Use clean cloth
gloves to insert the gas-discharge lamp.
- Only replace faulty HID lamps with the same type of
lamp. Bulb identification can be found on bulb socket or
glass cone.
- Harness connectors must engage correctly when
installed and must be checked for proper connection.
Repair Information
Contact Corrosion
Contact corrosion can occur if incorrect fasteners (bolts,
nuts, washers, etc.) are used.
For this reason, only fasteners with a special surface
coating are used.
In addition, rubber or plastic parts and adhesive consist of
non-conductive materials.
If there are doubts as to whether parts are suitable or not,
use new parts. Refer to the Parts Catalog.
Note:
- We only recommend original replacement parts, they have been
tested and are compatible with aluminum.
- We recommend using Audi accessories.
- Damage resulting from contact corrosion is not covered by
warranty.
Wire Routing
- Mark for example the fuel, hydraulic, vacuum, EVAP system
lines or electrical wires before removing to prevent confusing
them and to guarantee the installation position. Make sketches
or take photos if necessary.
- Due to the restricted space in the engine compartment, make
sure to allow for sufficient clearance to all moving or hot
components to avoid damaging the wires.
General Information
- For the applicable wiring diagram. Refer to
→ Wiring diagrams, Troubleshooting & Component locations.

Types of gasoline
The correct gasoline grade is stated on the inside
of the fuel filler door.

Description
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical situations,
such as if the vehicle is over steering or
under steering, or if the wheels are spinning. The
brakes are applied or the motor to
