2014 Mercedes-Benz CLS 3.0L Diesel · CF63 GPK

The most recent MOT test conducted on 22 January 2026 resulted in a pass with no defects recorded. When evaluating the overall maintenance trend, the vehicle appears to be in a stabilizing phase. Following a period between 2023 and 2024 where the vehicle required attention for a fractured coil spring, perishing tyres, and a binding brake caliper, the two most recent inspections have been entirely clean. This suggests that the previously identified mechanical issues have been addressed, though the absence of advisories in the most recent tests should be verified against the actual service records to confirm the quality and longevity of the repairs. The recorded mileage of 146,118 miles reflects a high level of usage for a twelve-year-old vehicle, averaging approximately 12,176 miles per annum. This consistent usage profile is generally positive as it suggests the vehicle has not been subject to the detrimental effects of long periods of standing, such as moisture buildup in the exhaust or brake seizure. However, the high cumulative mileage means that the vehicle has undergone significant mechanical stress. You should expect more frequent replacement cycles for consumables such as suspension bushes, shock absorbers, and various seals, as well as potential wear on the drivetrain components. During your test drive, you must pay close attention to the braking system and suspension integrity. The 2024 advisory regarding a binding offside front brake suggests that the caliper or its sliding pins may have been prone to sticking; listen for any unusual scraping or feel for any pulling to one side during braking. Furthermore, since the vehicle previously failed due to a fractured nearside front coil spring, listen intently for any clunking, knocking, or metallic banging sounds when navigating uneven road surfaces or speed bumps, as these are classic symptoms of failed suspension components or worn bushings. Finally, conduct a thorough visual inspection of the tyres. The history of perishing and uneven wear indicates that the rubber may be reaching the end of its serviceable life regardless of tread depth. Check the sidewalls for any fine cracking and ensure the tread is wearing evenly across the width of the tyre to rule out alignment or bush issues. Given the high mileage and age, you should also request evidence of scheduled fluid changes, particularly brake fluid and coolant, as these are subject to chemical degradation over time and are critical for the continued reliability of a high-mileage Mercedes-Benz.
