BMW 640d M Sport Auto (2015)
2015 BMW 640d M Sport Auto
CarHunch analysed 124 real MOT records for the 2015 BMW 640d M Sport Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2015 BMW 640D has a first-time MOT pass rate of just 26.5%—dramatically below the UK average of 80%—which is a serious red flag for potential buyers. The good news is that dangerous defects are absent from this cohort, but the reliability verdict is unmistakable: this model is consistently failing its MOT tests.
With a median mileage of 57,915 miles for a nine-year-old car, these examples are relatively low-mileage, yet they're still struggling to pass inspection, which suggests the failures aren't simply wear-and-tear related to high usage. Before buying one, get a full pre-purchase inspection from a specialist diesel mechanic who knows BMW 640Ds well—the pattern here points to systemic issues rather than isolated problems.
What to check before buying a 2015 BMW 640d 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.
