WARNING: This page is about a different car, the 2022 Audi SQ7, 2022 Audi S7, and 2022 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

If there are doubts about whether parts can be used or not, then use new parts. Refer to the Parts Information.

The use of Audi original replacement parts is recommended, since they are tested and approved.
The use of Audi original accessories is recommended.
