2000 Audi A8 — MOT failures & pass rate

Across 444 MOT tests, the 2000 Audi A8 recorded a 75.7% pass rate. That is effectively the same as executive cars of a similar age (23.6% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in brakes, suspension and lighting & signalling.

What the MOT record shows

No single area dominates — brakes (11.9%) and suspension (10.6%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are washers, service brake performance and catalyst emissions — washers alone was recorded 29 times.

Mileage is the strongest signal on the record: 14.3% of 60-90k cars fail, rising to 28.9% once past 150k — 2.0× the risk.

Suspension is the most common advisory, noted on 33.8% of tests — work that passed today but is likely due soon.

The trend is worsening — 23.3% of tests failed in 2021 against 25.4% in 2025, the usual pattern as a fleet ages.
