Should I check the MOT history before buying a 2003 Audi A8?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2003 Audi A8?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2003 Audi A8?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2003 Audi A8 sits just above the UK average at 81.3% first-time pass rate, but here's the concern: over a quarter of these cars (26.3%) have recorded a dangerous defect at some point, which is significantly higher than typical and should give any potential buyer pause. Petrol and diesel variants perform almost identically, both around 81% pass rate, so fuel choice won't materially affect reliability here.

These A8s are running at 94,410 miles on average—reasonable for their age—yet they're averaging 2.76 failures per test and a hefty 12.6 advisories, suggesting wear-related issues are commonplace. Before committing to one, get a pre-purchase inspection focused on suspension, electrical systems, and transmission, as luxury German saloons of this era tend to accumulate expensive problems quickly once warranty cover expires.

The 2003 Audi A8 has a decent first-time pass rate (81.3%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 12.6 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 828 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.
