2017 Mercedes-Benz CLA 2.1L Diesel · B16 MAR

The vehicle’s most recent MOT test occurred just five months ago on 2025-12-18, yet it failed twice on the same day at the same mileage (72,238), a highly unusual and concerning anomaly. This suggests either a technical error in the testing process or, more likely, a deliberate attempt to bypass proper inspection—though the absence of recorded defects makes this difficult to verify. The preceding MOT in December 2024 also passed and failed simultaneously at 67,818 miles, reinforcing a pattern of irregularity rather than genuine mechanical progression. Without visible defects or advisories in the official record, the roadworthiness status cannot be definitively assessed beyond the fact that the vehicle has not undergone a standard inspection for over five months. This lapse alone raises questions about whether critical components—such as suspension alignment, brake hydraulic integrity, or exhaust emissions systems—have been properly serviced or replaced. The recorded mileage of 72,238 miles over nine years equates to approximately 8,026 miles annually, a rate consistent with typical usage for this vehicle class. There are no obvious gaps or spikes in mileage between tests, though the lack of intermediate servicing records means wear on consumables like tyres, brake pads, and wiper blades cannot be confirmed. The most notable outlier is the simultaneous pass/fail on two consecutive MOT dates, which deviates from standard practice and warrants further scrutiny. If the vehicle has indeed been driven at this steady rate, components such as suspension bushes, coil springs, and brake calipers may require closer inspection, particularly if the owner has not maintained a separate service history. Given the irregular MOT outcomes, a buyer should prioritise an independent inspection of the suspension system, including bushings and shock absorbers, to confirm there is no excessive wear or misalignment. The braking system—particularly rear calipers and discs—should be checked for binding or uneven wear, as repeated MOT failures often point to recurring mechanical issues. Exhaust emissions should also be verified, as failing twice on the same test date suggests either a malfunctioning OBD system or an unaddressed catalytic converter or lambda probe. Structural integrity, including underbody corrosion and frame condition, should not be overlooked, especially if the vehicle has been parked in wet or salted environments. The absence of advisories in the record does not guarantee these areas are sound, but it does indicate the previous owner may not have documented routine maintenance.
