What should I replace at the same time?
Where labor overlaps, use heat-shrink crimp connectors rather than twist-and-tape for any pigtail splice, especially outside the cabin.
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 2021 Audi A6 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 2021 Audi A6?
First match the engine — each row shows which engine(s) the part fits. Then match the connector by terminal count and keyway, not just appearance — many families look identical but will not lock. The notes column carries position and trim qualifiers where they apply.
