What should I replace at the same time?
Where labor overlaps, clean or renew the battery terminals and grounds with any charging-system repair.
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 Bentley Bentayga was originally sold in the US, the safest choice is a part marked for the US market.

Every part on this page already fits all 3 engine options (3.0L V6 ELECTRIC/GAS Turbocharged, 4.0L V8 Turbocharged and 6.0L W12 Turbocharged). Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.
