2015 Mercedes-Benz A180 Sport Edition CDI 1.5L Heavy oil · MY10 CHA

A recurring theme of intermittent electrical faults and a single service‑brake anomaly runs through the MOT record, but the most recent two annual tests (2024‑10‑01 and 2025‑10‑01) were passed with no defects recorded, indicating that the vehicle has been able to operate without a failure for the last 24 months. Earlier failures – notably the 2023‑09‑07 rejection for a non‑functioning engine malfunction‑indicator lamp and an off‑side rear stop lamp, plus the 2021‑09‑04 failure for excessive fluctuation on the off‑side front service brake – highlight points where the vehicle required remedial attention, yet those issues have not resurfaced in the latest passes. At 152,189 mi for an eleven‑year‑old 2015 A‑Class the average annual mileage is roughly 13,800 mi, which sits above the typical UK passenger‑car average. The MOT chronology shows a regular yearly testing schedule with no significant gaps, suggesting the mileage has been accumulated consistently rather than in large, undocumented bursts. High cumulative mileage accelerates wear on consumables such as brake pads, discs, suspension bushings and engine bearings, so a prospective buyer should anticipate that these wear items may be approaching the end of their service lives despite the clean recent MOT outcomes. The 2021 service‑brake fluctuation failure points to possible hydraulic instability, worn pads, or a deteriorating master cylinder. On a test drive the driver should feel for any pulsation or judder in the brake pedal under moderate to heavy braking, listen for air‑pump noises, and check that the vehicle stops in a straight line without pulling. Even though the fault was not recorded in later tests, confirming consistent pedal feel and the absence of brake warning lights is prudent. Additionally, the 2023‑09‑07 engine MIL failure suggests a past fault in the engine management system; the dashboard should be inspected for an illuminated check‑engine light, and a diagnostic scan should be run to verify that no stored fault codes remain, as latent sensor issues can affect emissions and fuel economy. The MOT history also flags recurring wiper‑blade defects and a cracked off‑side rear OSR lamp in 2023. Verify that all windscreen wipers clear the glass without streaking and that the blades engage fully across their sweep; any chatter or missed sections may indicate worn blades or a failing wiper motor. Confirm that the rear OSR lamp illuminates correctly and that the cracked lens is not compromising visibility, especially in wet conditions. The 2020 advisory about a glow‑plug warning light remaining on warrants a check that the glow‑plug indicator is extinguished after start‑up and that the engine starts smoothly; a lingering warning could signal a misfiring cylinder or faulty sensor that may affect cold‑start performance. Addressing these items before purchase will give a clearer picture of the vehicle’s current roadworthiness.
