2019 Mercedes-Benz E 1.9L Electric diesel · LP19 RMV

The latest MOT test for this 2019 Mercedes-Benz E conducted on 2023-05-20 resulted in a passing outcome, with the vehicle meeting all roadworthiness standards. While the test recorded only minor defects in the windscreen wiper blades, which are straightforward and easily rectified, the presence of two advisories regarding the nearside and offside front brake discs—described as worn, pitted, or scored but not seriously weakened—represents a notable maintenance observation. Comparing this to the prior MOT in 2022-05-12, which showed no defects, the current advisories suggest a gradual wear progression on the brake discs, which is consistent with typical usage over time. This trend indicates a maintenance pattern that has remained stable rather than worsening, though the advisories warrant closer attention to prevent further deterioration or potential operational concerns. The recorded mileage of 70,065 miles for a vehicle aged seven years reflects a moderate annual usage rate of approximately 10,009 miles per annum, which is within the expected range for a car of this age and class. This pace does not suggest excessive wear from high-mileage accumulation, though it does imply that the vehicle has been in regular use rather than standing idle for extended periods. Without additional context on specific driving conditions—such as heavy loads, off-road use, or prolonged stationary periods—it is reasonable to assume that the suspension, drivetrain, and exhaust components have experienced consistent but not extreme stress. However, prolonged idleness can lead to issues like brake disc corrosion, fluid degradation, or battery drain, so any gaps in mileage should be investigated further to rule out these factors. For a prospective buyer, the most critical inspection areas should focus on the brake system, given the advisories from the latest MOT. Visually inspect the front brake discs for signs of excessive warping, glazing, or uneven wear beyond the noted pitting, and listen for any unusual grinding or squeaking noises during braking, which could indicate deeper wear or damage to the brake pads or calipers. On a test drive, check for a firm, even pedal feel without excessive sponginess or vibration, and ensure there is no brake pedal travel that suggests binding calipers or warped discs. Additionally, verify that the brake fluid level is within specification and that there are no leaks around the brake master cylinder or caliper components. Beyond the brakes, the windscreen wiper blades, though minor defects, should be replaced to restore clear visibility, especially given the vehicle’s age and potential exposure to environmental elements. Given the vehicle’s age and the moderate mileage, further practical checks should include examining the tyre condition for signs of sidewall cracking or perishing, which can occur even with low mileage if the tyres have been stored for prolonged periods or exposed to harsh conditions. Inspect the tyre tread depth for uniformity and any signs of uneven wear, which could indicate suspension or alignment issues. The 12-volt battery should be tested for charge capacity and corrosion on terminals, as standing vehicles can lead to battery drain or sulphation. Fluid levels, particularly the engine oil, coolant, and brake fluid, should be checked for any signs of degradation or contamination, with a reminder that these fluids should ideally be serviced according to the manufacturer’s schedule—even if the vehicle has not been driven extensively. Lastly, the exhaust system and emissions components should be visually inspected for corrosion or leaks, and the catalytic converter’s efficiency should be considered, especially if the vehicle has been driven under varying conditions.
