2013 MERCEDES-BENZ S-Class3.0L DIESEL

The vehicle currently holds a valid MOT but the maintenance history reveals a worsening trend in mechanical and electrical reliability. While it passed the test on 28 January 2026 at 471,650 miles, this followed a significant failure just three weeks prior. The January 8 failure highlighted multiple critical issues including an inoperative engine management light, excessive engine oil leaks, and a defective electronic parking brake. The fact that these faults were rectified within twenty days to achieve a passing result suggests a reactive approach to repairs rather than a proactive maintenance schedule. The mileage profile is exceptionally aggressive for a 13-year-old S-Class, with 471,650 miles recorded representing an average usage of over 36,000 miles per annum. Between January 2024 and January 2025, the car covered approximately 36,000 miles in exactly 12 months. This high rate of use places immense strain on the drivetrain and suspension components. The rapid accumulation of miles indicates the vehicle was likely used for long-distance motorway transit or work, which accelerates the wear of heavy-duty luxury components and cooling systems. A buyer must conduct a thorough inspection of the front suspension geometry, as the tester flagged worn ball joints on both the nearside and offside in early 2026 following similar play in 2024. The engine oil leak is also a primary concern, having progressed from a minor leak in 2024 to an excessive leak by early 2026. Furthermore, the electronic parking brake system has shown recurring faults over the last two years, indicating a persistent electronic or actuator failure that remains suspicious. Given the extreme mileage, the integrity of the turbocharger and the condition of the engine seals should be verified, as these components are nearing the end of their typical life cycles.
