GENERAL INFORMATION REGARDING HIGH VOLTAGE VEHICLES
| WARNING | Risk of unintended engine start For all work on high voltage vehicles, turn off the ignition and keep the key outside of the vehicle interior. |
| CAUTION | When working on vehicles with the ignition turned on or where the engine has been started, there is a risk of unintentional engine start and of being poisoned by gas in closed areas. There is a risk of clothes and body parts being pulled or getting stuck. Perform the following steps before turning on the ignition: Move the selector lever into P. Activate the parking brake Turn the ignition off. Open the hood. Connect the charger unit i.e., battery charger VAS 5095A to the battery jump start terminal for the 12V vehicle electrical system. Switch the ignition on. |
| CAUTION | There is a risk of being electrocuted if high voltage components are damaged. When working near high voltage components and wires, observe the following: Do not use cutting, deforming, sharp-edged tools or heat sources such as welding, solder, hot air or thermal glue. Perform a visual inspection before beginning any work in the area of high voltage components. Perform a visual inspection of the electric drive power and control electronics -JX1-, the vehicle electric drive -V141-, the A/C compressor -V470- and the high voltage lines when working in the engine compartment. Perform a visual inspection of the high voltage cable and the cover when working on the floor panel. Visually inspect the high voltage cables, the electronics and the high voltage system maintenance connector - TW -, when working in the luggage compartment. Perform a visual inspection of all of the potential equalization cables. Note the following when performing a visual inspection: No components should show any signs of exterior damage. The high voltage cable insulation and potential equalization cable insulation must not be damaged. The high voltage cables must not be deformed in any way. Every high voltage component must be marked with a red warning label. |
CONTACT CORROSION
Contact corrosion can occur if incorrect fasteners (bolts, nuts, washers, etc.) are used.
For this reason, only connecting elements with a special surface coating are installed.
Furthermore, all rubber or plastic and adhesive are made of non-conductive materials.
If there are doubts as to whether parts can be reused or not, use new parts.
Note. It is recommended to use only original replacement parts as they have been tested and are compatible with aluminum. It is recommended to use Audi accessories. Warranty does not cover contact corrosion damage.
LINES, WIRES ROUTING AND SECURING
When removing and installing hydraulic and pneumatic lines or electrical wires, make a sketch or take a photo to remember the original installation locations.
