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.
