Proper Location of Hose?
Hey guys, I'm a long time member of another mercedes forum but have been unable to log in because of a security breach they had relatively recently. I've been working on a spark plug change on my '06 SL600 when I noticed a hose (I think a vacuum house) that has been capped off at the rear of the left air cooler. I prefer to connect it to its proper port while I have everything out. Photo attached. Do any of you know where it goes?
