I've just bought a Mercedes SLK Compressor year 2000 with 52,000 miles on the clock. There are 2 small mechanical issues. First, the low coolant warning light comes on when the engine temperature goes over 80degC - the engine is not over heating, as it never goes above 90degC, and the coolant level seems fine when I check it. Secondly, the electric roof, keeps stopping in mid operation - to fix it, i turn the engine off then on, wait a few minutes, and then it finishes the operation. any ideas? thanks

 

Checked the fluid level?
Pump and reservoir located behind the hatch on the RHS of the trunk.
