2017 Mercedes-Benz V 2.1L Diesel · KU17 AAV

The most recent DVSA examination dated 24 August 2026 records no defects, indicating the vehicle presented at test in a roadworthy condition following its earlier failure. The trajectory across the last three tests suggests a period of deterioration followed by remedial action and subsequent stability. On 26 September 2025 the vehicle failed on major defects for excessively worn lower suspension arm ball joints on both front sides, which were presumably rectified before the clean pass on 8 October 2025 and again on 24 August 2026. The advisories recorded in September 2024 and October 2023, covering brake disc wear, brake pad thinning, and steering rack inner joint play, point to a component group that has been under sustained load and is approaching, or has already reached, the boundary of acceptable service life. Overall, the maintenance pattern is consistent with a high-mileage vehicle receiving active repair rather than passive neglect, but the buyer must recognise that the advisory items from 2024 remain unconfirmed in subsequent records and may have only been monitored rather than replaced. With 164,723 miles recorded against a nine-year registration, the vehicle has covered approximately 18,300 miles annually, which is substantially above the average for a passenger car of this vintage and indicates sustained commercial or long-distance private use. Such accumulation accelerates wear on all consumable and structural components, particularly the braking system, suspension bushings, drivetrain mountings, and the dual-mass flywheel if fitted to the manual variant. There are no large mileage gaps suggesting long periods of standing, which is mechanically favourable as it reduces the likelihood of seized calipers, perished rubber, and moisture accumulation in fluids. Nevertheless, the wear pattern observed in the MOT history aligns precisely with the demands placed upon a vehicle of this mileage, and any prospective purchase should be evaluated against the realistic expectation that further replacement of suspension and braking components is imminent. Turning to specific components, the front lower suspension arm ball joints flagged as major failures in 2025 are a known wear item on high-mileage Mercedes-Benz vehicles and warrant close physical inspection. On a test drive, listen for clonks or knocking from the suspension over uneven surfaces, particularly when turning or traversing speed humps, and observe whether the steering feels vague or imprecise. The advisories concerning the steering rack inner tie rod joints recorded in 2023 should also be re-examined, as play in these components progressively worsens and manifests as wandering steering, uneven front tyre wear, or a slight knocking sensation through the wheel. The rear brake pads noted as wearing thin in 2024 may now require replacement, and a thorough inspection of pad material thickness, disc run-out, and caliper slide pin operation is essential. Brake shudder under firm application, or a pull to one side during braking, would indicate warped discs or a binding caliper respectively. Given the mileage and age profile, physical checks should extend beyond the MOT record itself. Tyres should be examined for tread depth and, critically, for sidewall cracking or perishing consistent with age, as high-mileage tyres in regular service can degrade structurally even when tread remains adequate. The braking system should be assessed for corrosion on the rear discs where the handbrake is applied only intermittently, and the calipers should be confirmed as releasing cleanly to avoid hot rear wheels after driving. Brake fluid should be tested for water content, with replacement due on a calendar basis regardless of mileage, and the condition of the 12 volt battery verified as it is a common failure point on vehicles of this age. Engine oil and coolant should be checked for condition and any signs of emulsion or discolouration indicating head gasket concerns. Finally, verifying a full and consistent main dealer or specialist service history will be crucial in confirming that the high mileage has been supported by timely fluid changes, transmission servicing, and timing chain or belt replacement where applicable.
