I have an 2006 x5 (not the 2003 for saale) that has a small leak (maybe oil) that I was hoping to get checked out. I dont know the best place to post this. thanks
If it's the 3.0 then you're looking at either the oil filter housing and/or valve cover gasket. Those two are a guaranteed leak eventually. If it's the V8, sell it. Seriously. Not kidding.
