2005 Mercedes CLS 3.0L Diesel · DG55 YFT

The vehicle maintains a roadworthy status, but the mechanical history indicates a trend of worsening suspension-related wear and corrosion. The most recent test in July 2022 at 146,500 miles identified multiple points of concern including a corroded rear brake pipe, a leaking nearside rear shock absorber, and a defective exhaust mounting. While the vehicle passed, the accumulation of these defects suggests that the lower chassis components and rubber seals are reaching the end of their functional life and require proactive replacement. The recorded mileage of 146,500 miles over 21 years reflects an annual average of approximately 7,000 miles, which is consistent with a premium tourer of this age. However, there is a significant gap in the data, with the last recorded MOT occurring in July 2022. Given the current date in June 2026, the vehicle is four years overdue for its annual test. This long interval without official verification increases the likelihood that undetected degradation of rubber components or structural corrosion has progressed, especially considering the issues previously noted in 2022. A buyer must conduct a thorough physical inspection of the front and rear suspension assemblies. The history shows recurring issues with ball joints, steering rack joints, and coil springs dating back to 2019. Particular attention should be paid to the nearside rear coil spring and the brake pipe, as corrosion in these areas can lead to sudden structural failure if left unaddressed. The engine oil leak noted in 2022 should also be monitored to ensure it has not worsened beyond being non-excessive, and the steering column should be checked for signs of clicking or play given the previous reports of deterioration.
