2018 Mercedes-Benz GLC 2.1L Diesel · BF68 OET

The most recent MOT test on 2025-11-19 confirms the vehicle remains roadworthy at 52,078 miles, with no defects recorded. However, the preceding history reveals an unusual pattern: two consecutive failures in October and November 2024, both at around 43,000 miles, before passing again in late November 2024 and October 2023. While the vehicle ultimately passed its last two tests, the repeated failures suggest either a temporary issue resolved quickly or a minor oversight in pre-test preparation. The lack of advisory notes in any test implies no persistent concerns were overlooked by the tester, but the abrupt failures warrant scrutiny of components prone to intermittent failure—particularly brakes, suspension, or emissions systems—during the 2024 window. The mileage progression shows a steady accumulation of approximately 6,500 miles annually, which aligns with typical usage for a vehicle of this age. Notably, there is a 7,000-mile gap between the October 2023 and October 2024 tests, followed by a rapid 3,000-mile increase before the first failure in late October 2024. This suggests the vehicle may have been driven more aggressively or stored improperly during that period, potentially accelerating wear on suspension bushes, coil springs, or brake components. The absence of any advisory notes in the 2023 test further implies no pre-existing issues were flagged before the 2024 failures. Given the repeated failures in late 2024, a buyer should prioritise an independent inspection of the braking system, including rear brake binding, caliper wear, and disc thickness. The suspension—particularly rear bushes and coil springs—should be checked for excessive play or corrosion, as these are common causes of intermittent MOT failures. Additionally, the exhaust system should be examined for leaks or damage, as emissions-related faults often trigger repeated test failures. Structural corrosion, especially around wheel arches and sills, should also be assessed, as prolonged standing or poor storage could have accelerated deterioration. While the vehicle has passed its last two tests, the 2024 anomalies suggest these areas may require closer attention.
