Sunroof Audi A8 D3

Contact corrosion!

With the extensive use of aluminum construction, corrosion caused by contact between dissimilar metals may result if the wrong fastening components (screws, bolts, nuts, washers, rivets, plugs, grommets, adhesives, etc.) are installed.

For this reason, the manufacturer only installs fastening components that have a special surface coating, recognized by its greenish color, and only uses rubber parts, plastic parts and adhesives that are electrically non-conductive.

These parts, compatible for use with aluminum, are also available as replacement parts.

Use only Genuine Parts!

If there is any doubt about whether the old parts are suitable for re-use, always install new replacement parts.
