Audi A4 (2002)
2002 Audi A4
CarHunch analysed 28,872 real MOT records for the 2002 Audi A4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2002 Audi A4 fails its MOT 5 percentage points more often than the UK average, with a 75% first-time pass rate that's genuinely concerning. Worse still, over a quarter of these cars (27.3%) have recorded dangerous defects during their MOT history, which is a material buyer risk that warrants serious inspection before purchase.
These A4s are typically driven hard—the median mileage of 121,377 miles is high for a 22-year-old car—and the 19.8 average advisories per vehicle suggest corrosion and wear are rampant. Get a full pre-purchase inspection from an Audi-specialist mechanic, focusing on the suspension, brake lines, and electrical systems; the high advisory count means small issues accumulate quickly on this generation.
What to check before buying a 2002 Audi A4
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 27.3% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
