2018 Mercedes-Benz X 2.3L Diesel · HX68 XNB

The vehicle’s most recent MOT test, conducted on 25 September 2025 at 105,419 miles , confirms it remains roadworthy with no defects recorded. Over the past five annual tests—all passing without fail—there is no evidence of recurring mechanical issues or advisories that would suggest a worsening trend. The absence of any advisory notes or repeated failures across these intervals indicates the vehicle has undergone consistent MOT scrutiny without major concerns being overlooked. However, the near-identical mileage on the 2022 test dates (56,130 and 56,131 miles) suggests a possible administrative error or a brief period where the vehicle was not driven, though this does not imply mechanical neglect. The recorded mileage of 105,419 miles over 8 years —approximately 13,177 miles per year —is significantly higher than the average for a vehicle of this age, which typically accumulates around 7,000–10,000 miles annually . This elevated rate implies greater wear on high-stress components such as suspension bushes, coil springs, brake calipers, and drivetrain seals. The most rapid mileage jump occurred between 2022 (56,131 miles) and 2023 (72,558 miles) , a 16,427-mile increase in just over a year , which may indicate a period of heavier usage. While the MOT history shows no failures, this accelerated mileage should prompt a closer inspection of components prone to fatigue or premature failure. Given the lack of MOT advisories or failures, there is no direct evidence of unresolved structural or safety-critical issues. However, the high mileage warrants a thorough examination of suspension integrity , particularly the condition of rear coil springs and bushes , which are common failure points on this model at this mileage. The rear brake system should be checked for uneven wear or binding calipers, as high mileage can exacerbate thermal stress. Additionally, exhaust emissions —though not flagged in recent tests—may warrant verification, as catalytic converters can degrade over time with heavy usage. The underbody and wheel arches should be inspected for corrosion, especially if the vehicle has experienced wet or salted road exposure. A pre-purchase diagnostic scan for electrical faults or ABS system anomalies is also advisable, as these can develop silently despite passing MOT checks.
