2009 Mercedes-Benz E 3.0L Diesel · SC09 DAU

The latest MOT test on 7 August 2026 resulted in a pass, but this follows a failed inspection just two days prior with multiple serious brake-related defects, including a dangerous condition on the nearside rear brake disc and binding service brakes on both rear wheels. The history reveals a clear pattern of worsening brake system issues, with repeated advisories and failures concerning corroded brake pipes, worn discs, and parking brake inefficiency dating back to 2022. While the most recent pass suggests these faults have been addressed, the rapid reoccurrence of brake-related problems indicates a vehicle that has suffered from deferred maintenance and requires close scrutiny of the entire braking system’s integrity. At 17 years old with 108,651 miles, the annual mileage of approximately 6,391 miles per year is typical for a vehicle of this age, suggesting consistent rather than excessive or sporadic use. This moderate usage rate implies wear on consumables such as tyres, brakes, and suspension components should be commensurate with age and mileage, though the recurring brake pipe corrosion and binding issues suggest environmental exposure or prolonged periods of inactivity may have accelerated deterioration in these areas. A prospective buyer must prioritise a thorough inspection of the braking system, focusing on the condition of all brake pipes for corrosion, particularly at bends and connections, and verifying that the recently replaced or repaired rear discs, calipers, and parking brake mechanisms are functioning correctly. On a test drive, listen for grinding or dragging noises from the rear wheels, which could indicate residual binding, and check for a soft or spongy brake pedal, which may signal air in the system or further pipe degradation. The nearside front inner tyre wear advisory from the latest MOT warrants an examination of the tyre’s remaining tread depth and alignment, as uneven wear can point to suspension or steering geometry issues. Additionally, assess the TPMS fault noted in the latest advisory, as this could mask low tyre pressures or sensor failures, and inspect the ABS system for any lingering warning lights or fault codes, given the recent major defect. With a vehicle of this age, also check for perished rubber components such as suspension bushes, engine mounts, and coolant hoses, as well as signs of fluid leaks from the power steering, differential, or transmission. Finally, verify the service history to ensure time-based maintenance, such as coolant and brake fluid changes, has been carried out, as these are critical to long-term reliability.
