Do interior parts differ between 2018 Audi A3 engines?
Yes. Every interior part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of interior problems on a 2018 Audi A3?

What should I replace at the same time?
Where labor overlaps, replace the retainer clips with any panel removal — they are cheap insurance against squeaks.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2018 Audi A3 was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2018 Audi A3?
