Re: WTF is this and what can i do about it? (O_loung1)
As mentioned earlier, it is exhaust soot. A problem? Maybe; maybe not.
My '00 VR6 has been depositing soot on the tailpipe tips since it was new. However, after nearly 40,000 miles I haven't had a related "check engine" light, my performance is still excellent and the fuel mileage is correct as well. So I try not to worry about it and I wipe off the tailpipes when I wash the car.
You can get it checked by a VAG-COM or dealer service computer to see if anything is wrong. Good luck with it.
