Should I check the MOT history before buying a 2003 Audi A6?

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.

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.

The 2003 Audi A6 passes its MOT first time only 74.1% of the time, significantly below the UK average of 80%, and nearly 30% of these cars have recorded dangerous defects—a serious concern for any prospective buyer. Diesel variants fare slightly worse at 73.4% pass rate compared to petrol at 76.4%, suggesting the diesel engines are accumulating more problems by this age.

At around 113,800 miles median, these cars are carrying typical wear for their age, but they're failing heavily on non-critical items with an average of 20.7 advisories each—pointing to ageing trim, minor electrics, and suspension play rather than catastrophic issues. If you're considering one, factor in repair costs and insist on a full service history; the dangerous defect rate alone means a thorough pre-purchase inspection from a specialist is non-negotiable.

The 2003 Audi A6 has a below-average first-time pass rate (74.1% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 20.7 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 7,911 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.
