Parts for the Mercedes-Benz SL 400

Known issues

Common issues include problems with the retractable hardtop roof mechanism (check for smooth operation and any unusual noises), air suspension problems (if equipped), and oil leaks. The direct injection engines can be prone to carbon buildup. The complex electronics may experience glitches, so ensure all systems are functioning correctly. Look carefully for signs of water leaks, especially around the roof seals.

WOF tips

Pay close attention to the tyres, brakes, and suspension components, as these are subject to wear and tear due to the car's performance and weight. Ensure all lights are functioning correctly, including the adaptive headlights (if equipped). The retractable hardtop roof mechanism must be in good working order for WOF compliance. Check for any signs of fluid leaks, particularly from the engine and transmission. Corrosion can be an issue, especially underneath; give the car a thorough visual inspection.

About the Mercedes-Benz SL 400

All models feature a retractable hardtop roof, providing both coupe-like comfort and open-air enjoyment. The interior is beautifully appointed with high-quality materials and advanced technology. This facelifted model brought styling updates and improved fuel efficiency compared to earlier versions. Given NZ's climate, check the roof's operation thoroughly, as that mechanism's health is crucial.
