2018 Mercedes-Benz GLC 2.1L Diesel · LS18 AAZ

The most recent MOT test on this 2018 Mercedes-Benz GLC, conducted on 1 May 2025 at 48,124 miles, resulted in a pass with no defects recorded. However, the test immediately preceding it—on 1 May 2025 at 48,118 miles—was a failure, though no specific faults were logged. This suggests either a procedural error in the MOT system or, more likely, a genuine oversight in the tester’s report. The preceding tests in April 2024 and May 2023 also show identical mileage patterns: a pass at one mileage followed by a failure at a marginally lower mileage. Without detailed advisory notes, it is impossible to confirm recurring mechanical issues, but the lack of defects in the latest pass does not indicate a worsening trend. The vehicle has not exceeded its three-year MOT interval, and the most recent test was conducted just over a year ago, which is acceptable but not ideal for a vehicle of this age. The recorded mileage of 48,124 miles over approximately eight years equates to an average of 6,016 miles annually, a rate consistent with typical usage for a vehicle of this age. There are no significant gaps in mileage between tests, and no abrupt jumps that would suggest prolonged neglect or rapid wear. The most notable pattern is the repeated near-identical mileages at consecutive MOT tests, which could imply the vehicle was stationary or lightly used between tests rather than accumulating consistent mileage. This stagnation might indicate periods of storage or limited use, which could affect suspension compliance, tyre degradation, or minor corrosion development. Given the lack of specific faults in the MOT history, a buyer should prioritise an independent inspection of high-wear components that are not always captured in a standard MOT. The suspension—particularly coil springs, bushes, and dampers—should be examined for uneven wear or binding, as these are common issues in this model class and often develop gradually. Brake systems, including calipers, pads, and discs, warrant close scrutiny, especially if the vehicle has experienced sudden stops or heavy loads. Structural integrity, particularly around wheel arches, subframes, and the rear axle, should be checked for corrosion or damage, as this model is prone to rust in certain environments. Tyre condition, including tread depth and lateral wear, should also be verified, as the absence of tread-related failures in MOTs suggests either diligent maintenance or a risk of overlooking deeper issues.
