2017 Mercedes-Benz E 1.9L Diesel · SN16 JAR

The vehicle’s most recent MOT tests, conducted on July 5, 2025 , reveal a concerning pattern of repeated failures despite no recorded defects—an anomaly that warrants immediate scrutiny. Both tests at 138,546 miles were marked as failed, yet no specific faults were logged, which suggests either an administrative error or a deliberate bypass of critical checks. The preceding tests in July 2024 and February 2024 similarly show no defects, reinforcing that the vehicle has passed MOTs without addressing underlying issues. This inconsistency implies either a lack of thorough inspection or a history of unresolved mechanical concerns, particularly if the failures were not followed by repairs. Buyers should treat this as a red flag, as repeated MOT failures without explanation often indicate either a poorly maintained vehicle or a history of evading necessary repairs. The recorded mileage of 138,546 miles over nine years—approximately 15,400 miles annually —is unusually high for a vehicle of this age, suggesting either intensive use or prolonged periods of neglect. The gap between the February 2024 (126,930 miles) and July 2024 (136,031 miles) tests indicates 9,100 miles in just five months , a rapid accumulation that could strain suspension components, brake systems, and drivetrain integrity. The lack of intermediate maintenance records further raises concerns, as such high mileage between tests often correlates with deferred servicing. Without evidence of regular oil changes, fluid top-ups, or suspension/bush inspections, wear on critical parts like coil springs, sway bars, and steering linkages becomes more likely. Given the absence of specific MOT faults but repeated failures, a buyer should prioritise an independent inspection of braking systems —particularly rear calipers and discs—for binding or uneven wear, as this is a common cause of MOT rejections. The suspension geometry must be checked for worn bushes, cracked dampers, or misaligned wheels, as high mileage accelerates these failures. Structural integrity, including floorpan corrosion (common in Mercedes-Benz models) and exhaust system stability , should also be examined, as these are often overlooked until they compromise safety. The engine bay warrants scrutiny for oil leaks, worn serpentine belts, and coolant system integrity, given the vehicle’s age and mileage. Finally, the tyre tread depth and allignment should be verified, as the history suggests basic upkeep may have been inconsistent. A thorough pre-purchase inspection is essential to confirm whether the vehicle’s condition aligns with its MOT pass history.
