2017 Mercedes-Benz SLC 2.1L Diesel · AG02 GAL

The most recent MOT test on 2026-08-24 resulted in a clean pass, indicating no active roadworthiness defects at that time. However, the vehicle’s MOT history reveals a pattern of recurring advisories and a single dangerous failure, suggesting underlying wear issues that have persisted over several years. The most notable recurring advisory concerns the near-side front lower suspension arm pin or bush, which was flagged as worn but not to the point of excessive movement in both 2025 and 2022. This indicates progressive wear in a critical suspension component, which, if left unaddressed, could lead to reduced handling stability, uneven tyre wear, or even structural stress on the vehicle’s frame over time. The presence of multiple tyre-related advisories—including exposed ply or cords and tread wear close to legal limits—further underscores the need for careful attention to tyre condition, as these defects can compromise traction and safety, particularly in wet or adverse conditions. The vehicle’s recorded mileage of 65,464 miles for a 2017 model represents a moderate annual usage rate of approximately 7,274 miles per year, which is consistent with typical driving patterns for its age. However, the MOT history includes a major failure in 2022 for a rear tyre not fitted according to sidewall instructions, which may suggest either a previous incorrect rotation or a lack of adherence to manufacturer-recommended tyre rotation schedules. Additionally, the presence of a nail in a rear tyre in 2022 highlights the importance of regular tyre inspections, as sharp objects can accelerate tread wear or create dangerous blowout risks. The vehicle’s maintenance profile also shows periods where it may have stood for extended durations, as evidenced by the gaps between MOT tests, which can exacerbate issues like brake corrosion, suspension stiffness, or fluid degradation if not addressed promptly. For prospective buyers, this Mercedes-Benz SLC warrants a thorough mechanical inspection beyond the MOT checks, focusing on the suspension system. The worn near-side front lower suspension arm pin or bush should be replaced as soon as possible to prevent further alignment issues, uneven tyre wear, or potential suspension failure. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when the vehicle is driven over bumps or at speed, as these could indicate further wear in associated components like coil springs or control arm bushings. Additionally, check for excessive play in the steering linkage, which was also flagged in prior MOTs, as slight play can lead to misalignment or binding over time. Inspect the brake system for signs of corrosion on discs or calipers, especially on the near-side where standing may have accelerated rust formation, and listen for any grinding or squeaking noises during braking. The exposed ply in the front tyres necessitates immediate replacement, as exposed cords significantly reduce tyre safety and longevity, while the tread wear advisories should prompt a full tyre rotation and balancing to extend their service life. Beyond mechanical checks, examine the vehicle’s tyre sidewall for signs of perishing or cracking, which can weaken the tyre structure and reduce its ability to handle wet conditions safely. Given the vehicle’s age and the potential for prolonged standing, verify the condition of the 12-volt battery and associated electrical systems, as corrosion or weak terminals can lead to poor starting performance or electrical faults. Inspect the brake fluid reservoir for contamination or low levels, as brake fluid degrades over time and can cause spongy pedal feel or reduced braking effectiveness. Check the service history for any recorded fluid changes, particularly for coolant, brake fluid, and transmission fluid, as these should be replaced at manufacturer-recommended intervals, even if the vehicle has not been driven extensively. Finally, ensure the vehicle’s exhaust emissions system is functioning correctly, as the SLC’s petrol engine may require periodic emissions testing or servicing to comply with current regulations and maintain optimal performance.
