Need Help!! ( Black soot covered tips and lower bumper )
So, I have a 2009 XF Supercharged. My tips and lower bumper are always covered in black soot, I cant figure it out and I have asked the dealership on several visits with no recommended solution or fix. I have never noticed this on other XF's, I have a Mina Exhaust if that helps any. Even looking at Youtube vids of XF exhausts and the inside of the exhaust tips are even sparkling clean.

Do you floor it a lot? lol. Do you have an aftermarket tune? My guess is that it is just fuel from the car running rich so you shouldn't have to worry about it. Most factory ECUs are going to run on the rich side (since they have to tune for worst case scenario in regards to fuel, conditions, etc...), especially at high rpm's or high boost so this should be expected. Typically the stock catalyst or mufflers will take care of it so maybe the Mina is exacerbating it a little, but I have no experience with them so it's just a guess. I will tell you that this has always been a problem for me on my sports cars as they usually don't run any kind of catalyst to clean up the exhaust, the RX-7 is pretty bad about it. I have found that being generous about waxing around the effected area usually helps to make it really easy to wipe away.

IMO true on all of the above.
Best advice I can offer, is to get the tips as clean as can be, inside n out to start with.
Presumably washing your car regularly, include the tips on every wash giving them plenty of attention
See below the tips on my Audi A6 at around 7 years old and 114k miles, they look good as new.
Being a diesel it suffers probably at least, if not more so from heavy soot deposits under acceleration.
Hope it helps..
