On the 2005-2020 Mercedes-Benz SLK/SLC, the Vario Roof retractable hardtop on both R171 and R172 SLK/SLC models develops hydraulic leaks at the cylinders, lines, and pump. The most common leak points are the roof lock cylinders and the main lift cylinders. Leaking hydraulic fluid drips into the trunk area and can damage interior trim and the spare tire well.
