2017 Mercedes-Benz CLA 2.1L Diesel · SC66 OXM

The most recent MOT test on 31 March 2026 resulted in a pass, but only after a dangerous failure regarding a tyre with exposed cords. While the vehicle maintained a clean record between 2023 and 2025, the recent inspection shows a downward trend in mechanical condition with several new advisories. The presence of multiple issues involving tyres, braking components, and suspension gaiters suggests that the vehicle is currently experiencing accelerated wear, transitioning from a period of stability into a phase requiring more frequent maintenance of consumable parts. With 134,075 miles recorded over nine years, the vehicle has averaged approximately 14,897 miles per year. This is a high mileage profile for a 2017 Mercedes-Benz CLA. While high annual mileage can sometimes indicate more consistent motorway use, it also means the vehicle has undergone significant mechanical stress over its lifetime. Prospective buyers should anticipate that major components such as the suspension bushings, dampers, and various drivetrain elements may be approaching the end of their reliable service life, necessitating a more rigorous mechanical inspection than a lower-mileage equivalent. The specific advisories recorded in the latest test provide clear indicators of what to monitor during a test drive. The offside rear tyre showing inner edge wear is a strong indicator of incorrect wheel alignment or worn suspension geometry, such as degraded control arm bushes. You should listen for any rhythmic thumping or uneven tyre wear patterns. Additionally, the advisory for lipped front brake discs suggests the braking system is nearing replacement; pay close attention to any brake shudder or vibration through the pedal when decelerating. The perished anti-roll bar link gaiters are also a concern, as they can lead to grease loss and premature failure of the joints, which typically manifests as clunking noises over uneven road surfaces. Beyond the recorded defects, the history of a fractured coil spring in 2022 warrants a close visual inspection of the rear suspension assembly for any signs of corrosion or fatigue. Given the high mileage, it is vital to verify the service book for evidence of regular oil and fluid changes, as the MOT does not reflect the quality of engine or transmission maintenance. Check the underside for any signs of fluid leaks from the dampers or engine, and ensure that the missing rear tow eye cover is replaced to prevent moisture or debris from accumulating in the rear chassis area.
