With 4 Audi A6 models currently listed on Motoring Today, this page offers insights into its MOT performance, drawing on real DVSA test data. Of the 126,369 national MOT tests recorded for the A6, the model achieved an 82.85% pass rate. This figure reflects cars presented for their annual test and isn't a direct measure of lifetime reliability, as failures often cluster with a vehicle's age, mileage, and maintenance history, rather than the badge itself. The most common reasons for an Audi A6 failing its MOT are predominantly 'Lighting & electrical' (26% of failures), followed closely by 'Tyres' (25%), and then 'Suspension' (16%). For a used car buyer, this means paying close attention to all exterior and interior lights, including indicators and dashboard warning lights. Tyres should be thoroughly inspected for tread depth, sidewall damage, and correct pressure. Suspension issues can manifest as unusual noises over bumps, uneven tyre wear, or a less stable ride, so a test drive is crucial to assess these. The A6's cheapest model starts from £13,727, or a representative monthly payment of £421. While the MOT pass rate provides a useful snapshot, a full MOT history is available for every Audi A6 on Motoring Today, allowing you to review past advisories and failures before making a purchase decision.
