2017 Mercedes-Benz A-Class 2.1L Diesel · AU10 DEC

A single major fault – the Supplementary Restraint System warning lamp recorded as failed on 17 November 2022 – is the only serious blemish on an otherwise clean MOT history, and the vehicle has subsequently passed three consecutive tests (2022, 2025 and 2026) with no defects logged. Earlier advisories in May 2021 centred on front tyre wear, a thin front brake pad set and an off‑side headlamp aim that was out of tolerance; those items were not re‑recorded as failures in later years, suggesting they were addressed after the 2021 test. At 73,403 mi the car averages roughly 8,200 mi per year, a mileage rate that sits comfortably within normal usage for a nine‑year‑old Mercedes‑Benz A‑Class. The MOT chronology shows regular annual testing apart from the missing 2023 entry, but there are no sudden spikes in recorded mileage that would indicate unusually aggressive driving or prolonged periods of inactivity. This steady accumulation implies moderate wear on consumables such as tyres, brakes and suspension components, without the accelerated degradation seen on high‑mileage vehicles. When you inspect the car, verify that the air‑bag system now illuminates no warning lamp and, if possible, obtain a diagnostic read‑out to confirm the SRS fault has been cleared. Examine the front brake pads for residual thickness and listen for any squeal or judder under moderate braking; a thin pad set can re‑appear quickly if the caliper pins are sticking. The front tyres should be checked for sidewall integrity and tread depth on both nearside and off‑side wheels, as the 2021 advisories flagged slight sidewall damage and tread wear close to the legal limit – look for cuts, bulges or uneven wear that could indicate alignment or suspension issues. Finally, assess the steering and suspension by feeling for any pull to one side at steady speed, listening for knocks over bumps, and checking the condition of the front suspension bushes and coil springs for excessive play or corrosion. Although no corrosion or structural defects were recorded in the MOT data, a visual inspection of wheel arches, subframe and under‑tray for rust is prudent on a vehicle of this age. Confirm that the headlamp aim is now within specification, and verify that all lights function correctly. A thorough test‑drive combined with a professional pre‑purchase inspection will reveal whether the previously flagged items have been fully remedied and whether any emerging wear warrants immediate attention.
