ALUMINUM PANELS

The Audi Space Frame Concept
For the first time ever, not just for Audi, but for the entire world, vehicle bodies are being assembled as
ASF - Audi Space Frame.
ASF means: A combination of aluminum sections and aluminum die-cast joints.
All additional aluminum body pieces are attached to this new Audi frame construction with gas-shielded
welding, punch rivets, bonding and clinching (caulking two panels).
The special repair techniques are described in the following information.

CONTACT CORROSION

Contact corrosion may occur if unsuitable connecting elements (bolts, nuts, washers and so on) are used.
For this reason, only connecting elements with a special surface coating are installed (Dacromet). These
elements are distinguished by their greenish hue.
Furthermore, all rubber, plastic and adhesive materials used are non-conductive.
If there is any doubt about the reusability of parts, always install new replacement parts.
NOTE:
Only use genuine Audi replacement parts! They are tested and aluminum-
compatible.
Additional equipment must be approved by Audi of America!
Damage via contact corrosion is not covered by warranty!
THREADS
If damaged threads are repaired, inserts with galvanized coating must be used.
