2015 Mercedes-Benz A-Class 1.5L Diesel · LR65 KTC

A 2015 Mercedes-Benz A-Class showing 93,225 miles presents a mixed roadworthiness picture dominated by headlamp alignment concerns and emerging tyre deterioration, rather than any major mechanical or structural failures. The most recent test on 25 August 2026 was a pass, but it carried an advisory noting slight damage, cracking, or perishing on all four tyres. Prior to that, the vehicle passed cleanly in September 2025, August 2024, and September 2023. However, that September 2023 entry was preceded by a failure on the same date, with both nearside and offside front headlamps recorded as having an aim that was too low. The fact that both headlamps were out of adjustment simultaneously suggests either a deliberate adjustment issue or a suspension-related geometric concern that warrants attention, even though the immediate problem was resolved to allow a subsequent pass. The pattern indicates a fundamentally sound vehicle that has nonetheless exhibited lighting and rubber-related concerns. With an average annual accumulation of roughly 8,475 miles over eleven years, this A-Class has been driven at a near-typical rate for its age, meaning consumables such as brake pads, discs, tyres, and suspension bushes have likely been exercised normally rather than sitting idle. There are no significant gaps in the testing history that would suggest long periods off the road, which is relevant because extended standing can dry out rubber seals, degrade brake hydraulics, and promote corrosion. The consistent year-on-year testing through 2023, 2024, 2025, and 2026 points to active use, and the mileage progression appears steady rather than erratic. That said, a Mercedes of this vintage at nearly 93,000 miles should be expected to have worn suspension components and driveline items that are not always fully captured by an MOT test, so the mileage level itself is a meaningful consideration for any prospective buyer. Given the recorded advisory on all four tyres, a close physical inspection of the rubber is essential, paying particular attention to sidewall cracking, tread depth across the full width, and any uneven wear patterns that might indicate alignment or suspension geometry issues. The tyres should be checked for their age, as cracking on all four simultaneously can indicate they have aged beyond their effective service life regardless of remaining tread. On a test drive, listen for any knocking or clonking from the front suspension over uneven surfaces, which could point to worn anti-roll bar drop links, control arm bushes, or top mount bearings, all known wear items on the W176 A-Class at this mileage. Steering should feel precise without vibration through the wheel, and any pulling to one side under braking or acceleration could indicate worn suspension linkages or brake caliper issues. The headlamp aim failure on both sides in 2023 should not be dismissed lightly, and it would be prudent to verify that the headlamp assemblies are correctly seated, that the adjustment motors are functioning, and that the beam pattern is currently within legal limits, particularly if the vehicle has been loaded or if the ride height has altered due to spring settlement. When test driving at night, confirm that both dipped beams project a flat, level cutoff line and do not dazzle oncoming traffic. For a diesel or petrol A-Class at this mileage, also listen for any timing chain rattle on cold start, check for oil leaks around the engine and turbo, and confirm that the seven-speed dual-clutch transmission (where fitted) changes smoothly without hesitation or shudder. A pre-purchase inspection on a ramp would be advisable to assess underbody condition, including subframe mounting points, brake pipe corrosion, and exhaust integrity, none of which have been flagged but all of which become more relevant as the vehicle accumulates further mileage.
