BMW M4 Competition Package S A (2017)
2017 BMW M4 Competition Package S A
CarHunch analysed 126 real MOT records for the 2017 BMW M4 Competition Package S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2017 BMW M4 Competition has a serious reliability problem: just 34.8% pass their MOT first time, nearly half the UK average of 80%, with zero vehicles ever flagged for dangerous defects but clearly systemic issues elsewhere. The absence of dangerous faults is reassuring, but the low pass rate suggests recurring minor or moderate problems that require attention before test.
At an average of 41,168 miles, these cars are lightly used for their age, yet they're still struggling through MOT—pointing to design or maintenance issues rather than wear and tear. With negligible advisories recorded (0.0 per vehicle), the failures aren't warnings but actual defects, meaning a buyer should budget for immediate remedial work and expect ongoing costs typical of high-performance BMWs; have a pre-purchase inspection by a specialist M4 technician before committing.
What to check before buying a 2017 BMW M4 Competition Package S A
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.
