2020 Mercedes-Benz EQC 400 AMG Line 4MATIC Electric · AP70 SZR

The most recent MOT test conducted in February 2026 resulted in a pass, but the presence of advisories indicates a recent downward trend in mechanical condition. Following a clean test in early 2024, the vehicle has transitioned from tyre wear advisories in 2025 to suspension component advisories in 2026. This progression suggests that while the vehicle remains roadworthy, wear-related components are beginning to reach the end of their serviceable life. The previous major failure in late 2023 regarding body component damage suggests a prior incident that required rectification, making it important to ensure all structural repairs were carried out to manufacturer standards. With 35,967 miles recorded over approximately six years, the vehicle has averaged roughly 6,000 miles per year. This is considered low mileage for a premium electric vehicle of this age. While this typically means less mechanical strain on the electric motors and drivetrain, low-usage patterns can present specific risks. Long periods of standing can lead to the degradation of rubber seals, suspension bushes, and tyres, as well as the potential for brake components to seize or corrode due to a lack of regular thermal cycling and movement. The current advisories for slight play in both the nearside and offside front suspension arm ball joints are significant. This wear will inevitably progress, leading to a failure in future inspections. During your test drive, pay close attention to the steering response and listen for any rhythmic knocking, clunking, or popping noises when traversing bumps or turning the wheel at low speeds. You should also inspect the front tyres for uneven wear patterns, particularly on the edges, which could indicate that the suspension wear is affecting the wheel alignment or that the previous tyre wear advisories have not been fully addressed through replacement or alignment. Beyond the recorded advisories, the low annual mileage necessitates a thorough physical inspection of age-related items. Check the tyre sidewalls for signs of perishing or cracking, as rubber can harden and lose grip over six years even if tread depth remains high. Inspect the brake discs for heavy surface corrosion or signs of binding calipers, which are common in low-use vehicles. It is also essential to verify the service history for time-based maintenance, such as brake fluid replacement, rather than just mileage-based intervals. Finally, confirm the condition of the 12V auxiliary battery, as low-frequency driving can often lead to its premature failure.
