2016 Mercedes-Benz A 180 D SE Executive 1.5L Heavy oil · OV66 YLO

The most recent MOT, carried out on 30 December 2025, was passed with no recorded defects, and the preceding five annual tests have all resulted in passes. The only blemish in the ten‑year record is a single failure in December 2020 for a major fault in the supplementary restraint system and an advisory for a glow‑plug warning. Since that event the vehicle has consistently cleared MOT without further issues, indicating that any remedial work undertaken after 2020 has restored the car to a stable condition and that the maintenance trend is now steady rather than deteriorating. At ten years old the A‑Class has logged 140,329 miles, equating to an average of roughly 14 000 miles per annum. This is above the typical UK usage pattern and suggests a relatively high level of component wear. The mileage accumulation is consistent year on year, with no obvious gaps that would indicate prolonged periods of inactivity. Consequently, wear items such as the suspension bushings, coil springs, CV joints, drive‑shaft universal joints and the braking system are likely to be approaching the latter stages of their service life and may require closer inspection or proactive replacement. Given the historic SRS fault, a prospective buyer should verify that the air‑bag warning lamp is extinguished on the dashboard and request a diagnostic scan to confirm that the supplementary restraint system control unit is fault‑free. Any lingering fault codes could indicate a compromised air‑bag deployment capability, which is a safety-critical issue. The glow‑plug advisory points to a possible problem with the diesel ignition system; the buyer should listen for rough idle, hard starting or mis‑fires, and have the glow‑plug module and individual plugs tested, as failure can affect emissions compliance and engine smoothness. Beyond the electronic warnings, the car’s age and mileage dictate a thorough physical appraisal. Examine the tyre sidewalls for cracking, dry rot or uneven wear that would betray mis‑alignment or worn suspension components. Check the 12‑volt battery for sulphation and verify its cranking voltage, as prolonged high mileage often coincides with extended periods of storage. Inspect the brake discs for surface corrosion, glazing or scoring, and ensure the calipers move freely without binding. Finally, confirm that the service history reflects timely oil, coolant and brake‑fluid changes, as time‑based fluid degradation can lead to internal wear even if mileage intervals have been met. A careful test‑drive listening for clunks, vibrations or shuddering will reveal the condition of the suspension, steering rack and drivetrain before committing to purchase.
