Should I check the MOT history before buying a 2017 Audi S4 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 S4 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 S4 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 S4 TFSI Quattro Auto reliable?

Based on MOT data from 131 vehicles, the 2017 Audi S4 TFSI Quattro Auto has a first-time MOT pass rate of 44.3%, indicating below-average reliability 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 S4 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.

The 2017 Audi S4 TFSI is a serious reliability concern, with only 44.3% of vehicles passing first-time MOT versus the UK average of 80%—a stark 36-point shortfall that signals persistent issues with this generation. The good news is that dangerous defects are absent from this cohort, but the high failure rate suggests buyers should expect repeated visits to the workshop.

With an average mileage of just under 52,000 miles, these cars are relatively low-mileage for their age, yet failures are still mounting, which points to design or build quality problems rather than wear-and-tear. The 0.15 average failures per vehicle and complete absence of advisories suggests problems tend to be binary—either the car passes or it fails on something material—so any prospective buyer should insist on a pre-purchase inspection by a specialist Audi technician and budget heavily for repairs.
