This 2016 Audi A6 S Line TDI Ultra is a real reliability concern—only 57.5% pass first time against the UK average of 80%, meaning nearly four in ten fail their MOT. The diesel variant, which accounts for 99.7% of this cohort, performs identically poorly at 57.3%, and while dangerous defects are absent from the data, the low pass rate alone flags serious issues worth investigating.
With median mileage of 86,680 miles for an eight-year-old car, these are typically well-used examples, yet the average 0.17 failures per vehicle suggests problems run deep and consistent across the fleet. Before viewing one, request the full MOT history to identify what's repeatedly failing—transmission, emissions, suspension, or brakes—and budget for corrective work or walk away unless the price reflects heavy repair bills ahead.
The 2016 Audi A6 S Line TDI Ultra S A passes its MOT first time more often than most UK vehicles (93.9% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 672 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
