As the X3 was happily gurgling down the gas at the Exxon station this evening (
), I took a peek at the underbody as periodic inspection to see if there's anything broken/dirty. To my surprise, I saw these two "leaks", one on each side. First one is from the left side, second one is from the right side.
Is this any kind of leak? I tried to rub some off on my fingers so I could see the true color/smell, but there wasn't enough (so I just got my hands all black and dirty). I washed the car this evening, but it's probably not water since I'd been on the highway and such. It's not the AC, because I haven't had the climate control on today at all. So does anyone have an idea what part the leak is taking place and/or what the leak could be?
