2022 Mercedes-Benz EQA 350 AMG Line 4MATIC Electric · PJ22 ABV

The 2022 Mercedes-Benz EQA 350 AMG Line 4MATIC has a flawless MOT history, with both recent tests conducted on 2025-06-03 and 2026-06-11 passing without any recorded defects or advisories. This consistent performance over the past two years indicates a stable maintenance record, suggesting that the vehicle has been subject to regular servicing and that any underlying mechanical issues have either been addressed promptly or remain within acceptable operational limits. The absence of recurring failures or advisories—particularly common in hybrid-electric models where electrical system diagnostics and battery health monitoring are critical—further reinforces confidence in the vehicle’s current roadworthiness and reliability. While the lack of defects does not guarantee future longevity without further inspection, it does provide a solid foundation for a prospective buyer to proceed with due diligence. The recorded mileage of 45,276 miles for a vehicle aged four years represents a reasonable annual usage rate of approximately 11,319 miles, which is within the expected range for this class of electric vehicle. Lower mileage could imply periods of stationary use, such as extended periods parked in a garage or less frequent driving, which may have contributed to minor wear on consumables like brake pads or tyres. Conversely, higher mileage would accelerate wear on suspension components, drivetrain elements, and electrical connections, particularly in an electric model where battery management systems and high-voltage wiring are sensitive to prolonged stress. The current mileage, however, does not suggest excessive driving intensity or rapid wear progression, though a thorough inspection should still account for potential standing-related issues, such as brake disc corrosion or caliper binding, which can develop over time even with low mileage. For the prospective buyer, the most critical checks should focus on the vehicle’s electrical and hybrid systems, given its age and the potential for cumulative wear in these areas. Given the absence of MOT defects, the next step is to verify the integrity of the high-voltage battery system, including checking for any signs of swelling, leaks, or unusual odours, which could indicate internal battery degradation or thermal management system failure. On a test drive, listen for any electrical whining, intermittent power loss, or unusual resistance in the high-voltage door locks or windows, as these could signal wiring issues or failing connectors. Additionally, inspect the battery’s thermal management fluid level and condition, as this fluid degrades over time and must be replaced at specified intervals to prevent overheating and component failure. Beyond electrical systems, the vehicle’s conventional components should also be scrutinised. Given the EQA’s hybrid architecture, the internal combustion engine and associated drivetrain components remain largely unchanged from a conventional petrol model, but the 4MATIC transmission system—particularly the torque converter and planetary gear set—may exhibit signs of wear after four years of use. Check for any unusual noises during acceleration or gear shifts, such as whining or grinding, which could indicate fluid degradation in the transmission or internal component wear. Inspect the suspension for signs of excessive play or clunking, especially around the coil springs and suspension bushes, as these can develop stiffness or failure over time. Finally, verify the tyre condition, focusing on sidewall perishing, uneven wear patterns, or signs of hydroplaning susceptibility, as these can degrade performance and safety. A thorough visual inspection of the undercarriage for fluid leaks—particularly from the battery, exhaust system, or underfloor seals—should also be conducted, as standing fluids can accelerate corrosion and structural damage.
