FOUND THE LEAK!!-- I think......
Was changing the oil on my SL500 last weekend thensaw oily residue on top of the A/C compressor area. For the past 3 months, I 've been caring for a minature leak inmy A/C system that a sniffer can't detect. To my surprise, I saw the hoses are covered with "soot" like substance...maybe it's a gasket or the hose itself leaking out.... fresh oily substance colored light brown is the best description I can give... Did I hit a pot of gold????What would you do next?????
