2004 Mercedes-Benz CLK 2.6L Petrol · FA54 RTX

The most recent MOT test conducted in January 2026 resulted in a pass, yet the recorded advisories suggest a concerning trend toward age-related deterioration. While the vehicle passed without defects in early 2025, the subsequent return of advisories regarding brake pipe corrosion and wheel distortion indicates that the mechanical condition is beginning to decline. The transition from minor suspension ball joint play in 2024 to more specific component issues in 2026 suggests that the vehicle is entering a phase where wear and environmental corrosion are becoming more prevalent. With 108,557 miles recorded over 22 years, the vehicle has averaged roughly 4,934 miles per year. This is considered low mileage for a vehicle of this age, implying it has likely been used for occasional trips rather than heavy-duty commuting. While this suggests lower wear on the engine and transmission, low-use vehicles are prone to specific issues such as seal drying, fluid contamination, and rubber perishing. The recent MOT history, specifically the advisories regarding suspension and brake components, aligns with the typical symptoms of a vehicle that has spent significant time stationary. You must pay close attention to the advisory regarding the offside front brake pipe. The fact that it is covered in grease is a common method used to mask the extent of corrosion; you should inspect this area carefully for any signs of fluid weeping or significant surface degradation. During your test drive, listen for any knocking or clunking sounds from the front end, which could indicate that the previously noted suspension ball joint play has progressed. Furthermore, monitor the vehicle for any vibrations or rhythmic thumping that may be caused by the reported distortion of the offside rear inner road wheel. Given the low annual mileage, a thorough inspection of the tyres is essential; look for sidewall cracking or perishing, as tyres can become unsafe due to age even if the tread remains deep. Check the brake discs for heavy corrosion or pitting, which is common in vehicles that do not see regular use. It is also vital to verify the service history to confirm that oil, coolant, and brake fluid changes have been carried out according to the manufacturer's time intervals rather than solely on a mileage basis. Finally, check the battery health and ensure the electrical systems, such as the noted inoperative fog light, are addressed to ensure full operational reliability.
