How do you jump start an Audi a6?

To jump-start an Audi A6, first ensure both vehicles are turned off. Connect the positive (+) terminal of the dead battery to the positive terminal of the working battery, then connect the negative (-) terminal of the working battery to a grounded metal surface on the Audi (not directly to the negative terminal). Start the working vehicle and let it run for a few minutes before attempting to start the Audi. Once the Audi starts, disconnect the cables in the reverse order, ensuring not to let the clamps touch each other.
