2009 Mercedes-Benz R-Class 3.0L Diesel · OY09 XOC

The most recent MOT test for this 2009 Mercedes-Benz R-Class, conducted on 19 November 2022 at 127,213 miles, confirms the vehicle remains roadworthy with no defects recorded. Over the past five annual tests—all passing without fail—the record shows a consistent pattern of compliance with UK roadworthiness standards. The absence of advisories or recurring failures suggests the vehicle has been maintained at a baseline level, though this does not preclude hidden issues in non-MOT-tested areas such as drivetrain seals, internal suspension wear, or corrosion. The final test date, nearly four years ago, means a thorough inspection of high-wear components is essential before purchase, particularly given the vehicle’s age and mileage. The mileage progression indicates steady usage, averaging around 7,500 miles annually, which aligns with typical expectations for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, though the November 2019 record includes a near-duplicate entry—one passing and one failing at 114,021 and 114,100 miles respectively—which may reflect an administrative oversight rather than mechanical irregularity. The lack of advisories or partial failures in earlier tests implies no obvious neglect, but the absence of service records means potential wear in non-MOT areas—such as timing chain tensioners, differential fluid condition, or brake master cylinder seals—cannot be confirmed. Given the vehicle’s age and mileage, a buyer should prioritise an independent inspection of the suspension system, focusing on worn coil springs, deteriorated bushes, and binding calipers, all of which are common in high-mileage Mercedes-Benz models. The brakes, while not flagged in MOTs, should be assessed for uneven wear, corrosion on caliper slides, or glazed discs, particularly if the vehicle has seen wet or heavy urban use. Structural integrity is another critical area; corrosion around wheel arches, sills, and the subframe is often underestimated in older vehicles, and visible rust or flex in these regions could indicate deeper issues. Finally, the exhaust system should be checked for leaks or excessive corrosion, as catalytic converter failures are not always captured in MOT tests.
