SFV A4

So we've been having some rain here in L.A. -off and on the last few weeks. I couldn't avoid it and the car got dirty to the point I could not wipe it down. So tonight, I did my first wash (was new in July). My conclusion: this is about the easiest car to wash! Now I got that new look again... well just about. I see some slight swirls coming in on the black. I knew it was bound to happen evenutally. So no biggie. Time for a wax next week. Funny thing tonight... had to saw up the X-Mas tree on the sidewalk. The xenons lit up the scene beautifully. hehe Finally, this annoying buzzing/rattle sound in my steering wheel is getting louder and louder. Anyone have any idea what this is? It's right where the wheel connects with the column on the top side (at the "crack"). Dealer couldn't hear it a few months ago, but it's gotten louder since. Regards.
