2016 Mercedes-Benz CLA 2.1L Diesel · B6 GRC

The vehicle’s most recent MOT test on 10 November 2025 at 81,362 miles passed without defects, confirming current roadworthiness. However, the history reveals a concerning pattern of two consecutive failures in early 2025—both at 76,422 miles —despite the second attempt passing. This suggests either a recurring issue resolved between tests or a temporary oversight in pre-MOT preparation. The most recent pass in November 2025 indicates the problem, if unresolved, has not re-emerged, but the gap between failures (just 14 days apart ) implies a critical component was either repaired hastily or the fault was intermittent rather than structural. No advisories or defects appear in the latest tests, but the repeated failure at the same mileage hints at a potential underlying fault in brakes, suspension, or emissions systems that may recur. The recorded mileage of 81,362 miles over 10 years averages 8,136 miles per year , which is typical for a vehicle of this age and class. There are no obvious gaps in service intervals, though the 14-day gap between the two 2025 failures suggests either a rushed repair or a fault that was temporarily masked. The most significant mileage jump occurred between December 2023 (68,401 miles) and January 2025 (76,422 miles) , a 7,021-mile increase in under a year , which could indicate either intensive use or a period of neglect before the failures surfaced. The lack of advisories in the latest tests suggests no major deferred maintenance, but the rapid mileage accumulation post-failure could imply the owner prioritised driving over thorough diagnostics. Given the recurring failure at ~76,000 miles , a buyer should prioritise a full brake system inspection , including rear calipers, discs, and binding mechanisms, as these were likely the cause. The suspension bushes and coil springs should also be checked for excessive wear, particularly if the vehicle exhibits uneven handling or clunking noises. Corrosion at wheel arches, subframes, and exhaust mounts—common in this model—must be assessed, especially if the car has been parked in wet conditions. The exhaust emissions system (catalytic converter, DPF if applicable) should be tested for efficiency, as repeated failures often stem from catalytic degradation or sensor faults. Finally, the structural integrity of the chassis and body panels warrants scrutiny, as hidden rust can compromise safety without immediate MOT failure. The absence of advisories in recent tests does not guarantee these areas are flawless, so a professional pre-purchase inspection is strongly advised.
