Should I check the MOT history before buying a 2017 Audi S5 TFSI Quattro Auto?

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.

What corrosion should I look for when inspecting a 2017 Audi S5 TFSI Quattro Auto?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2017 Audi S5 TFSI Quattro Auto?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2017 Audi S5 TFSI Quattro Auto reliable?

Based on MOT data from 233 vehicles, the 2017 Audi S5 TFSI Quattro Auto has a first-time MOT pass rate of 83.8%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2017 Audi S5 TFSI Quattro Auto?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

This 2017 S5 is a genuine reliability concern—only 51.6% pass first time against the UK average of 80%, and that headline figure masks a catastrophic split: the 107 petrol variants have a 3.4% pass rate while 126 "Other" fuel vehicles (likely hybrid or alternative powertrains) achieve 92.6%. The dangerous defect rate of 0.4% is mercifully low, but the first-time failure rate tells you the petrol S5 consistently arrives at MOT with problems.

At 53,000 miles median for a seven-year-old car, mileage is reasonable and not the culprit—the issue is engineering reliability, not wear. The 0.18 failures and 0.1 advisories per vehicle average suggest these aren't minor niggles but genuine faults that need fixing, likely suspension, emissions, or electrical gremlins typical of this generation's complexity. If you're considering one, insist on a pre-purchase inspection by an Audi specialist and budget heavily for remedial work; alternatively, seek out one of the non-petrol variants where the data is dramatically more favourable.
