2024 Mercedes-Benz EQB 350 AMG Line Premium + 4M Electric · LR74 PEO

The vehicle in question presents a significant challenge for a comprehensive roadworthiness assessment due to the absence of any recorded DVSA MOT history, which precludes any evaluation of maintenance trends or past defect progression. Without prior test results, there is no basis to determine whether the EQB 350 AMG Line Premium + 4M has adhered to a consistent maintenance schedule, experienced gradual wear-related failures, or faced intermittent issues that might require prompt attention. The lack of historical data also means that any potential underlying mechanical issues—such as suspension component wear, brake system degradation, or fluid system corrosion—cannot be contextualised within a timeline of deterioration. For a prospective buyer, this absence of prior inspection records necessitates a heightened focus on the vehicle’s current condition and a thorough, proactive inspection to mitigate risks that might otherwise have been flagged by a DVSA inspector. The recorded mileage remains unknown, which complicates any assessment of the vehicle’s usage profile and its potential wear state. The 2024 model year represents a relatively new platform for the EQB, and without a defined mileage benchmark, it is impossible to gauge whether the car has accumulated excessive wear from high annual mileage or has been maintained at a lower, more sustainable pace. If the vehicle has been driven at a rate significantly above the UK average of around 10,000–12,000 miles annually, this could accelerate wear on components such as the drivetrain, exhaust system, and suspension, potentially leading to premature failure of critical elements like the rear axle seals, transmission fluid degradation, or suspension bushings. Conversely, if the mileage is low relative to age, the vehicle may have undergone minimal operational stress, but this does not absolve it from age-related issues such as tyre sidewall perishing, battery ageing, or fluid system degradation due to prolonged inactivity or lack of service intervals. The absence of mileage data forces the buyer to rely on other indicators, such as the vehicle’s condition, service history (if available), and the results of a comprehensive physical inspection. Given the lack of MOT history, the buyer must conduct a meticulous, multi-faceted inspection to address both immediate and latent risks. First, focus on the suspension system, as the EQB’s high-end trim and 4M transmission may have components like coil springs, shock absorbers, and suspension bushes that are prone to wear, particularly if the vehicle has been driven at higher speeds or over rough terrain. Look for signs of excessive play in the steering or uneven ride quality, which could indicate failing suspension elements. During a test drive, listen for clunking noises from the front or rear suspension, especially when transitioning between rough and smooth surfaces, as this often signals bushings or ball joints nearing failure. Next, examine the brake system for signs of corrosion on brake discs, particularly on the rear discs which may show more wear from standing or infrequent use. Check for binding calipers, which can lead to uneven brake pad wear or a shuddering sensation when braking. Additionally, inspect the tyres for sidewall cracking or perishing, which can compromise structural integrity and safety, especially if the vehicle has been stored for extended periods without use. For fluid systems, the buyer should prioritise the brake fluid, transmission fluid, and coolant, as these degrade over time regardless of mileage. Brake fluid absorbs moisture, which can lead to reduced braking performance and corrosion of brake components. If the vehicle has not been serviced recently, the brake fluid should be flushed and replaced, and the brake system inspected for leaks or excessive heat damage. The transmission fluid, particularly in a 4M automatic transmission, should be checked for contamination or sludge buildup, which can impair shifting performance. The coolant system should be inspected for leaks or corrosion, as the EQB’s high-performance engine may require more frequent servicing to prevent overheating or long-term damage. Finally, the battery should be tested for health, as the 2024 model’s electrical systems may rely on a robust 12V battery to support the electric powertrain and high-end infotainment. A weak or failing battery could lead to electrical gremlins or a complete loss of power, so a load test or visual inspection for corrosion on terminals is essential. If the vehicle has been driven at low mileage, the buyer should also verify that the service book has been stamped for the manufacturer-recommended intervals, such as the oil change and filter replacement at 15,000–30,000 miles, to ensure the engine and drivetrain remain in optimal condition.
