Adhesive Surfaces

WARNING: This page is about a different car, the 2025 Audi A4 allroad and 2025 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Adhesive surfaces must be free of oil, silicone, Teflon, debris, moisture and oxide layers.
For bonds that require a grinding bare/sanding of the adhesive surfaces, clean the surface prior to grinding. If this is not observed, impurities may be introduced into the base material from the grinding.
Do not weld, grind and polish in the immediate vicinity.
No sprays containing silicone may be used in the workshop area where the adhesive is being used.
Pay attention to other specifications regarding adhesive surfaces in the repair information.
