I've noticed a lot of soot round the tips of the exhaust of my 2006 CLS Diesel when I'm driving.
Not so much when just driving along at slow speeds or constant 60-70mph on motorway which is most of my driving, but the moment I give it a bit of oomph, there is a lot of soot that comes out the back.
Can anyone tell me why this is and how I can prevent this?
