Bolts And Nuts

WARNING: This page is about a different car, the 2023 Audi S3, 2023 Audi RS 3, 2023 Audi A3 Quattro, and 2023 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

Loosen the bolts opposite the tightening sequence.
Tighten the bolts or the nuts in steps to secure the covers and housings according to the specified tightening sequence and methods.
Bolts or nuts which secure covers and housings should be loosened and tightened diagonally and in steps if no tightening sequence is specified.
Always replace self-locking nuts and bolts.
If not otherwise specified: clean the threads of the bolts which were installed with locking fluid with a wire brush. Then insert the bolts with fluid locking compound. Refer to the Parts Information.
The threaded holes into which the self-locking bolts or bolts with locking fluid are installed must be cleaned (for example with a thread tap). Otherwise there is the risk that the bolts could break off when they are removed again.
The tightening specifications given apply to non-lubricated bolts and nuts.
