2008 Audi R8 4.2 Quattro S A

CarHunch analysed 114 real MOT records for the 2008 Audi R8 4.2 Quattro S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2008 Audi R8 is a serious reliability concern: just 3.3% of these cars pass their MOT first time, compared to the UK average of 80%, and the petrol version shows a 0% pass rate across 110 tested vehicles. No dangerous defects have been recorded, which is the only bright spot, but the near-total failure rate suggests systematic issues that plague this model year.

The average mileage of 56,342 miles is relatively low for a 16-year-old car, yet these vehicles are failing MOTs with almost no advisories or documented failures per vehicle—indicating that defects are either catastrophic (causing immediate failure) or that testing data isn't capturing the full picture. If you're considering one, insist on a full pre-purchase inspection by an R8 specialist and expect significant remedial costs before it'll pass an MOT.

What to check before buying a 2008 Audi R8 4.2 Quattro S A

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.
