Audi Rs4 Quattro (2006)
2006 Audi Rs4 Quattro
CarHunch analysed 117 real MOT records for the 2006 Audi Rs4 Quattro. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2006 Audi RS4 Quattro is a reliability concern: only 38.3% pass on the first attempt against the UK average of 80%, which means nearly two-thirds of these cars fail their initial MOT. The good news is that dangerous defects are absent from this dataset, so when failures occur they're typically manageable rather than safety-critical issues.
These cars are running at genuinely high mileage—averaging 103,681 miles at nearly 18 years old—which partly explains the struggle, though it doesn't fully excuse the gap to the national average. With less than 0.3 failures per vehicle on record, the failures themselves are infrequent when they happen, suggesting the real issue is inconsistent maintenance and age rather than inherent design flaws. If you're considering one, get a pre-purchase inspection from an Audi specialist and budget for preventive work on wear items before the MOT.
What to check before buying a 2006 Audi Rs4 Quattro
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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
