2007 Mercedes-Benz S-Class 3.0L Diesel · C27 TER

Persistent issues with suspension components and fluid leaks define the mechanical profile of this Mercedes-Benz S-Class, with the most recent test on 18 May 2026 showing a pass despite several recurring advisories. The vehicle has demonstrated a pattern of failures involving hydraulic systems and suspension integrity, specifically regarding shock absorber leaks and ball joint dust covers. While the 2026 result indicates the vehicle met minimum standards, the presence of an oil leak and corrosion on the rear subframe mounting area suggests ongoing degradation that has been noted across multiple testing cycles. The recorded mileage of 106,648 miles over approximately 19 years equates to an average annual usage of roughly 5,613 miles. This represents a significantly lower-than-average mileage accumulation for a vehicle of this age. While lower mileage can reduce wear on certain high-friction components, the MOT history shows that specific rubber and hydraulic elements, such as suspension bushes and shock absorbers, have still reached the end of their functional life. The usage pattern suggests the vehicle may spend considerable time stationary, which can sometimes exacerbate the deterioration of seals and rubber dust covers. Prospective buyers should pay close attention to the suspension and braking systems during a physical inspection and test drive. The history of major failures involving the offside front hydraulic brake caliper and nearside front shock absorber leaks necessitates a thorough check for any signs of weeping or active dripping around these components. On the road, listen for knocking or clunking noises when driving over uneven surfaces, which could indicate worn ball joints or suspension arm bushes, as these have been flagged in several recent tests. Additionally, monitor the brake pedal for any sponginess or inconsistent pressure, given the previous major failure of the hydraulic caliper. The advisory regarding rear subframe mounting corrosion and the presence of an oil leak requires careful scrutiny. While the subframe corrosion was not deemed excessive in May 2026, it is a structural area that should be inspected for depth and extent to ensure it is not progressing. The oil leak, though described as not excessive, should be traced to its source to determine if it originates from the engine, gearbox, or a seal. Finally, the recurring advisories for tyres worn close to the legal limit on both front and rear axles suggest that tyre replacement is an imminent requirement. Check for any uneven tread wear or pulling to one side, which could indicate alignment issues following the previous suspension component failures.
