2018 Mercedes-Benz GLC 2.1L Diesel · M22 PAD

The most recent MOT test completed on 24 August 2026 resulted in a pass, but it marks a significant departure from the vehicle's previously clean inspection history. While the vehicle maintained a defect-free record between 2023 and 2025, the latest report introduces several advisories concerning suspension, braking, and tyre wear. This indicates a shift in the maintenance trend where age-related wear on consumable components is now coming to the forefront, suggesting that the vehicle is entering a phase where more frequent component replacements will be necessary to maintain optimal roadworthiness. With a recorded mileage of 54,120 miles over approximately eight years, the vehicle has covered an average of roughly 6,765 miles per year. This usage profile is relatively low for a Mercedes-Benz GLC and suggests the vehicle has not been subjected to heavy commercial or high-intensity motorway use. While this lower mileage is generally positive for the longevity of the engine and drivetrain, the recent advisories suggest that the lack of high-frequency usage may have allowed certain components, such as the brake discs, to suffer from surface corrosion or pitting due to environmental exposure rather than extreme mechanical wear. Prospective buyers should exercise caution regarding the offside front lower suspension arm ball joint, which is reported to have slight play. During a test drive, it is vital to listen for any rhythmic knocking, clunking, or metallic clicking sounds, particularly when traversing speed bumps or navigating undulations in the road surface. Any perceptible change in steering feel or a lack of precision in direction changes could indicate that the play is progressing. Furthermore, the advisories for pitted and scored brake discs on both rear wheels should be addressed. You should monitor for any brake shudder or vibration through the pedal during deceleration, and inspect the discs visually for heavy surface corrosion or deep scoring that could affect braking efficiency and potentially lead to binding calipers. The advisory regarding the nearside rear tyre being worn close to the legal limit and specifically on the edge is also a point of concern. Uneven wear on the tyre edge is a classic symptom of incorrect wheel alignment, such as improper camber or toe settings. If you proceed with the purchase, it is highly recommended to have a professional four-wheel alignment check performed alongside the replacement of the worn tyre and rear brake components. Failure to correct the alignment will result in premature wear on any new tyres fitted. Finally, check the overall condition of the remaining tyres for sidewall cracking or perishing, which can occur on vehicles of this age even if the tread depth remains sufficient.
