Model-level reading
What changes the warranty calculation
286 submitted complaints appear in the Audi A6 file. They stretch across 11 model years, with the middle annual count at 20.
Report volume peaks at 113 for 2019. Without registration counts or equal vehicle age, the peak cannot serve as a defect ranking.
Among the matching repair categories, Engine replacement or major internal repair tops the parts midpoints at $7,000. That is the system I would locate in both the factory warranty and any proposed service contract.

These are ranges across EPA configurations, not the specification of every trim. The VIN and original window sticker settle the exact equipment. Source: FuelEconomy.gov vehicle data, dataset updated 2026-06-16.
