Should I check the MOT history before buying a 2004 Audi Rs6?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

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.

We have limited data for the 2004 Audi Rs6 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
