BMW 320d M Sport Auto (2017)
2017 BMW 320d M Sport Auto
CarHunch analysed 361 real MOT records for the 2017 BMW 320d M Sport Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2017 BMW 320D M Sport is underperforming at first-time MOT, with a 64% pass rate that sits 16 percentage points below the UK average of 80%—a meaningful reliability concern for used car buyers. The good news is that dangerous defects are rare (0%), and the few failures that do occur are minor ones averaging just 0.14 per vehicle, suggesting problems are fixable rather than structural.
At around 70,000 miles on the clock, these cars are showing their age more noticeably than average vehicles, which partly explains the higher failure rate. Before buying, get a full pre-purchase inspection from a BMW-specialist mechanic, as the first-time pass numbers suggest some aspect of ownership—likely emissions systems or suspension components common to diesel BMWs—needs close attention.
What to check before buying a 2017 BMW 320d M Sport Auto
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.
