Audi A4 (2012)
2012 Audi A4
CarHunch analysed 17,321 real MOT records for the 2012 Audi A4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2012 Audi A4 passes its MOT slightly more often than the UK average at 83.8%, but this masks a serious concern: 38.6% of these vehicles have recorded a dangerous defect at some point, well above acceptable levels and a genuine red flag for prospective buyers. Petrol versions fare better at 87% first-time passes compared to diesels at 83.4%, suggesting the petrol engine is marginally more robust.
At 87,400 miles median, these A4s show typical wear for their age, yet they're racking up 2 failures and nearly 14 advisories per test on average—pointing to age-related deterioration across electrics, suspension and braking systems. Before purchasing, get a pre-buy inspection that specifically covers brake components, electrical gremlins, and suspension geometry, as these are where this generation habitually falls short.
Petrol vs Diesel
Pass rate difference of 3.6 percentage points — worth knowing if you're choosing between the two.
What to check before buying a 2012 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.
- ⚠️ 38.6% 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.
