Audi Rs6 (2004)
2004 Audi Rs6
CarHunch analysed 117 real MOT records for the 2004 Audi Rs6. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 Audi RS6 passes its MOT slightly above the UK average at 81.5%, which is respectable, but one in four owners will encounter a dangerous defect at some point—a notably high figure that demands careful pre-purchase inspection and service history review. This is a high-performance machine, and that complexity shows in the data: owners face nearly 3 failures per test and almost 19 advisories, suggesting ongoing maintenance costs will be steeper than a standard saloon.
At nearly 80,000 miles median, these cars have been driven hard but not run into the ground, yet the sheer volume of advisory items hints at wear on ageing performance components—turbos, suspension, brakes, and electronics all accumulate issues. Before committing to one, have a pre-purchase inspection by an Audi specialist focus specifically on turbocharger condition, suspension geometry, and fuel system integrity, as these are where your repair bills will bite deepest.
What to check before buying a 2004 Audi Rs6
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.
- ⚠️ 26.5% 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.
