Bonded Joints, Checking And Repairing
WARNING: This page is about a different car, the 2025 Audi S3, 2025 Audi RS 3, and 2025 Audi A3 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
Particular attention should be given to these areas when diagnosing collision damage and servicing.
Note the following points: do not use a chisel to test the strength of a joint and do not release the tension by hammering, as this will destroy the bonded joint.
These areas should be inspected particularly closely when diagnosing collision damage and after performing straightening work.
If the area is not accessible with pop rivets, it must be repaired with a gas-shielded weld seams. In this case, the entire area must be welded again, as the heat produced by welding destroys the bonded joint. The gas-shielded arc weld seams should be welded working from the thinner to the thicker panel. At the same time, the fumes must be ventilated.
