2018 Mercedes-Benz A-Class 1.5L Diesel · AX68 OAC

The most recent MOT on 15 May 2026 was passed, but it recorded an advisory that the off‑side front suspension arm ball‑joint exhibits slight play. This follows a similar advisory on the nearside front ball‑joint at the August 2024 test, while the 2021 MOT highlighted front tyre tread approaching the legal limit. No outright failures have been logged, indicating that the vehicle has remained mechanically compliant, yet the recurrence of ball‑joint play suggests a gradual deterioration of the front suspension rather than an abrupt failure, and the tyre wear advisory points to a need for timely tyre replacement. At 106 504 mi the car is roughly eight years old, giving an average annual mileage of about 13 300 mi. This is above the typical UK average of 10‑12 000 mi per year, implying a relatively high usage rate. The mileage record shows no large gaps, so the wear on consumables such as tyres, brakes, and suspension components is likely to be proportional to the distance covered. Higher mileage accelerates the fatigue of bushings, ball joints, and steering linkages, and can also increase the likelihood of internal engine and transmission wear, especially if service intervals have not been strictly adhered to. Prospective buyers should give the front suspension close scrutiny. A visual inspection of the ball‑joint boots for cracks, oil stains, or torn rubber is essential, and the joints themselves should be checked for excessive movement by applying a lever at the wheel hub while the tyre is off the ground. During a test drive listen for clunking or knocking when turning the steering wheel at low speed, and feel for any looseness or wandering under braking. The front tyres, which were flagged in 2021, should be measured for tread depth across the centre and both edges; uneven wear may indicate mis‑alignment or worn suspension components that will need correction before the next service. Replacement of the ball‑joints and a full alignment are likely to be required within the next few thousand miles to avoid progressive wear. In addition to the suspension, the buyer should inspect age‑related items. Check the condition of the brake discs and pads for surface corrosion, glazing or uneven wear, and verify that the calipers move freely without binding. The 12‑volt battery, now nine years old, should be load‑tested to confirm it can hold charge, especially if the vehicle has spent periods stationary. Examine all fluid reservoirs for colour and level – engine oil, coolant, brake fluid and power‑steering fluid should be refreshed at least every 24 months regardless of mileage. Look for rust on wheel arches, under‑body panels and suspension mounts, and ensure that any corrosion is superficial rather than structural. A full service history, with stamps confirming timely oil changes and filter replacements, will give added confidence that the car has been maintained in line with Mercedes‑Benz recommendations.
