BMW M4 S A (2014)
2014 BMW M4 S A
CarHunch analysed 150 real MOT records for the 2014 BMW M4 S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2014 BMW M4 S-A is a reliability concern: just 39.4% pass on their first MOT attempt, almost half the UK average of 80%, and this dramatic shortfall suggests systemic issues with the model rather than isolated problems. The complete absence of dangerous defects (0%) is reassuring from a safety perspective, but the overall picture is troubling for potential buyers.
At an average mileage of 51,756 miles for a decade-old M4, these cars are being driven hard and maintained inconsistently, which partly explains the poor first-time pass rate. With only 0.2 average failures per vehicle and virtually no advisory issues recorded, the problem appears to be that owners are simply not keeping up with preventative maintenance before the test—if you're considering one, budget for immediate pre-purchase diagnostics and factor in higher-than-average servicing costs.
What to check before buying a 2014 BMW M4 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.
