Safety Precautions when Working on the High-Voltage System
WARNING
High Voltage Poses Life-Threatening Risk
The high-voltage system is under high-voltage. Electrocution can cause death or very serious personal injury.
- Individuals with electronic/medical life and health sustaining machines in or on their person cannot perform any work on high-voltage systems. Life and health sustaining machines are for example pain killer pumps, implanted defibrillators, pacemakers, insulin pumps, and hearing aids.
- Have the high-voltage system de-energized by a qualified person.
There is a Risk Of Injury Due to the Engine Starting Unexpectedly.
On electric - hybrid vehicles an active ready mode is difficult to identify. Parts of the body can be clamped or pulled.
- Switch off the ignition.
- Place the ignition key outside of the vehicle interior.
Caution
Risk of Damaging the High-Voltage Cables.
Misuse can damage the insulation of high-voltage cables or high-voltage connectors.
- Never support objects on the high-voltage cables and the high-voltage connectors.
- Never support tools on the high-voltage cables and the high-voltage connectors.
- Never sharply bend or kink the high-voltage cables.
- When connecting pay attention to the coding of the high-voltage connectors.
Safety Precautions when Working near High-Voltage Components
WARNING
High voltage poses life-threatening risk
The high-voltage system is under high-voltage. Electrocution can cause death or very serious personal injury from damaged high-voltage components and high-voltage cables.
- Perform a visual inspection of the high-voltage components and the high-voltage cables.
- Never use tools that are for cutting, deformed, or sharp edged.
- Never use welding, soldering, thermal adhesive or hot air.
Safety Precautions during Road Test with Testing Equipment
WARNING
There is a risk of injury caused by unsecured testing equipment.
If the front passenger airbag deploys during an accident, unsecured testing equipment becomes a dangerous projectile.
- Secure the testing equipment on the rear seat.
or
- Have a second technician operate the testing equipment on the rear seat.
Safety Precautions when Working on Cooling System
WARNING
Risk of scalding due to hot coolant
The cooling system is under pressure when the engine is warm. Risk of scalding due to hot steam and hot coolant.
- Wear safety gloves.
- Wear protective eyewear.
- Reduce the pressure by covering the coolant expansion tank cap with a cloth and carefully opening it.
Repair Information
Line Routing and Securing
When loosening or removing and installing hydraulic, pneumatic lines or wires, draw sketches or take pictures. This will ensure they are installed in their original positions.
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 installed.
In addition, rubber or plastic parts and adhesives are made of non-conductive materials.
If there are doubts whether parts can be reused, use new parts according to the Parts Catalog.
Note
- The use of original replacement parts is recommended, since they are tested and are compatible with aluminum.
- The use of Audi accessories is recommended.
- Contact corrosion damage is not covered under warranty!
Adhesive Surfaces for Adhesive Tape
- The vehicle must be at room temperature before installing self-adhesive covers, door seals, etc. with adhesive tape, for example.
- The adhesive surfaces on the body must be free of dust and grease.
- Clean the adhesive surfaces using Cleaning Solution -D 009 401 04-.
- Apply Bonding Agent -D 355 205 A2- on the body-side adhesive surfaces using the Applicator -D 009 500 25- and let dry.
- Warm the adhesive surfaces to approximately 40 º (104 ºF) using a hot air blower.
- After installing, press on the covers with adhesive tape again using a roller.
- After installing, pull on the components by hand to check for a secure fit.
Secured Threaded Connections
Installed bolts that are "microencapsulated" must be replaced, and the threaded holes must be cleaned with a suitable thread tap.
