2009 Mercedes S-Class 3.0L Diesel · PF09 PJF

The vehicle currently holds a valid MOT certificate issued on 18 March 2026, confirming its roadworthiness status is up to date. The maintenance trend remains stable, though the recurring failure regarding the engine malfunction indicator lamp suggests a persistent electronic or sensor-related issue that has not been permanently rectified. While the vehicle passed the most recent inspection, the pattern of failing and passing on the same day indicates that the underlying fault was likely cleared or bypassed rather than repaired, which warrants caution regarding the long-term health of the engine management system. The recorded mileage of 184,843 miles over seventeen years averages approximately 10,873 miles per annum, which aligns with expected usage for a luxury saloon of this vintage. Notably, the mileage accumulation has slowed significantly in recent years, with only 1,053 miles added between February 2023 and March 2026. This limited usage suggests the car may have spent extended periods in storage or served as a secondary vehicle, which can sometimes lead to issues with seized brake components or degraded rubber seals that do not always manifest during a standard MOT test. Prospective buyers should focus their inspection on the engine management system, specifically investigating why the malfunction indicator lamp triggered failures in both 2023 and 2026. Given the age and complexity of the S-Class platform, you must verify the operation of the air suspension system, as these components are prone to wear and expensive to replace. Check for any signs of uneven tyre wear or knocking noises from the suspension bushes, as these are common failure points for high-mileage Mercedes models. Finally, inspect the underside for any evidence of corrosion on the subframes and brake lines, as the vehicle's recent low-mileage profile may mask underlying structural deterioration.
