The 2017 Audi A8 is significantly more reliable than the UK average, with a 93.6% first-time MOT pass rate compared to 80% across all vehicles—a genuinely strong result. However, nearly one in five examples (19.1%) have recorded a dangerous defect at some point, which is a material concern for prospective buyers and worth investigating on any specific car before purchase.

At 50,080 miles median, these A8s show typical wear for their age, yet they're racking up relatively few failures (0.49 per vehicle) despite accumulating four advisories on average, suggesting most issues remain minor. Run a full service history check and have any candidate inspected by an Audi specialist, particularly focusing on the safety-critical systems where those dangerous defects are turning up.

The 2017 Audi A8 passes its MOT first time at roughly the UK average rate (93.8%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
Good baseline reliability. A 93.8% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 4 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 703 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.
