2015 Mercedes-Benz A-Class 1.5L Diesel · RX65 ODT

The vehicle is currently roadworthy but the maintenance trend shows a clear decline in the most recent inspection. After three years of clean records between 2022 and 2024, the November 2025 test at 215,964 miles revealed multiple mechanical failures. While the car passed a re-test just one day later at 216,036 miles, the transition from a defect-free status to a list of electrical and mechanical faults suggests that preventative maintenance has been neglected until the MOT deadline forced action. The mileage profile is exceptionally high for an 11-year-old vehicle, averaging nearly 20,000 miles annually. The data shows consistent, heavy usage, with over 25,000 miles covered between October 2023 and November 2024, and another 45,000 miles in the final year leading to the most recent test. This rapid accumulation places significant stress on the drivetrain, suspension geometry, and braking systems, which explains the degraded state of the brake components and anti-roll bar linkages noted during the high-mileage intervals. A physical inspection must focus on the braking system and suspension integrity. The November 2025 report flagged pitted and scored discs on both axles, along with front pads reaching the wear limit just a week prior. The recurring failure of the anti-roll bar linkage ball joint dust covers indicates ingress of grit, which will lead to premature joint failure and knocking noises. The buyer should also verify the source of the non-excessive oil leak, as these on high-mileage engines often indicate significant seal or gasket degradation that worsens over time. The supplementary restraint system warning lamp recorded in the 2025 failure requires a professional diagnostic check to ensure the artwork deployment is fully functional beyond a simple sensor fault. Given the high mileage and the history of minor windscreen damage, the vehicle should be checked for signs of impact or excessive wear on all rubber bushings that are not covered by standard MOT testing.
