2021 Mercedes-Benz V 300 AMG Line Marco Polo D A 1.9L Diesel · A1 KKW

A relatively clean recent inspection history follows a period of significant mechanical failures in mid-2024, indicating a shift from a failed status to a defect-free record. While the vehicle passed its most recent test on 26 May 2026 without any recorded defects, the 2024 failure highlighted critical safety concerns involving the engine management system and tyre integrity. The progression from a dangerous tyre defect and an inoperative engine malfunction indicator to a clean pass in 2025 and 2026 suggests that the primary electrical and structural tyre issues identified previously have been addressed. The recorded mileage of 22,182 miles over approximately five years represents a low annual accumulation of roughly 4,436 miles. This usage profile is significantly lower than the UK average for a diesel MPV of this class, which typically suggests lighter road use or extended periods of stationary storage. Mechanically, while lower mileage often results in less wear on drivetrain components and braking systems, such low usage can sometimes lead to different wear patterns on consumables or the development of minor leaks in seals and dampers due to infrequent operation. Prospective buyers should pay close attention to the nearside rear suspension, as the 2024 MOT record included an advisory for light oil misting on the shock absorber. Although no defect was recorded in the subsequent 2025 or 2026 tests, the presence of oil misting can be a precursor to a full seal failure. During a test drive, it is essential to monitor the vehicle for any irregular bouncing or excessive oscillation when driving over undulations or speed bumps, which could indicate that the damping characteristics of the rear shock absorber have been compromised. The previous dangerous failure regarding a tyre bulge caused by structural separation necessitates a thorough visual inspection of all four tyres for any signs of sidewall deformation, cracking, or uneven wear. Additionally, because the engine malfunction indicator light (MIL) was previously recorded as inoperative, a diagnostic scan should be performed to ensure the vehicle's onboard monitoring systems are communicating correctly with the dashboard. Listen for any irregular engine idling or hesitation during low-speed manoeuvres to confirm that the engine management system is functioning within specification.
