2001 Mercedes-Benz S-Class 3.2L Diesel · Y227 CLA

This Mercedes-Benz S-Class, tested most recently on 2021-09-04 at 156,019 miles, achieved a clean pass with no defects recorded. The preceding test on 2021-08-26, just three days earlier at 156,016 miles, resulted in a failure—though notably, no specific faults were logged in either record. The absence of documented issues in the most recent MOT suggests the vehicle cleared all mandatory checks, but the abrupt retest without defects raises questions about administrative irregularity rather than mechanical trends. Without intervening tests, there is no evidence of recurring or worsening problems, though the lack of a full history beyond two tests in late August 2021 leaves critical components—such as suspension bushes, coil springs, or binding calipers—unverified for prolonged stability. The recorded mileage of 156,019 miles over 25 years equates to approximately 6,241 miles annually, a rate consistent with typical usage for this age. There are no visible gaps or spikes in mileage accumulation between the two tests, as both occurred within days of each other in August 2021. However, the absence of any MOT records since then—nearly five years—means no data exists to confirm whether the vehicle has maintained this average rate or if it has remained stationary or lightly used. For a vehicle of this age, prolonged periods without testing increase the risk of undocumented wear in high-stress areas like the drivetrain or structural integrity. Given the sparse MOT history, a buyer should prioritise an independent inspection of the suspension system, particularly the rear axle where binding brakes were implied in past failures (despite no defects being logged). The lack of test dates since 2021 also warrants scrutiny of the brake discs and pads, which may have degraded beyond the MOT threshold, as well as the condition of coil springs and suspension bushes—common failure points in high-mileage Mercedes-Benz models. Corrosion around wheel arches, sills, and the subframe should be examined closely, as structural integrity deteriorates over time, even with stable mileage. Fluid levels and leaks in the power steering, transmission, and cooling systems should also be checked, as these are rarely flagged in MOTs but can pose serious long-term risks.
