2018 Mercedes-Benz E 1.9L Diesel · KA55 DOM

The latest MOT test carried out on 5 December 2025 resulted in a pass, though it introduced several advisories that warrant attention. The overall trend in the MOT history is largely stable, with only one prior failure in March 2021 due to a dangerous fractured near-side front road wheel, which was subsequently rectified. The absence of further failures since that point suggests a period of consistent maintenance, but the emergence of brake disc lip and rear inner tyre sidewall damage in the most recent test indicates a potential decline in component condition that should be monitored. At 88,720 miles over eight years, the vehicle has accumulated an average of approximately 11,090 miles per annum, which aligns with typical usage for a car of this age. This mileage suggests a balanced wear pattern without extreme high-use stress or prolonged inactivity, though it remains high enough to expect some degradation in consumables such as brakes, tyres, and suspension components. The steady annual mileage implies that mechanical wear has progressed naturally rather than being accelerated by erratic usage. The advisories for lipped rear brake discs and cracking or perishing rear inner tyre sidewalls are particularly noteworthy. Lipped brake discs indicate wear that, if unaddressed, can lead to reduced braking efficiency, vibration through the pedal, or scoring of the brake pads. On a test drive, listen for grinding or juddering under braking and inspect the discs for deep grooves or uneven surfaces. The tyre sidewall damage is a safety concern, as cracking or perishing can compromise structural integrity, increasing the risk of a blowout. Check the tyres for visible cracks, bulges, or uneven wear, and confirm their age—tyres over five years old, regardless of tread depth, should be scrutinised closely. Additionally, verify that the child seat has been removed to allow a full inspection of the adult seatbelt. Given the vehicle’s age and mileage, a thorough inspection of the suspension and steering components is advisable, as bushes, ball joints, and shock absorbers may exhibit wear. Pay attention to any clunks or knocks over rough surfaces, which could indicate worn suspension mounts or bushes. Fluid levels and condition should also be checked, particularly the brake fluid, which degrades over time and can absorb moisture, reducing braking performance. Finally, assess the 12V battery health, as older batteries are prone to failure, especially in vehicles with high electrical demand or infrequent long journeys. A load test is recommended to confirm its condition.
