Yea the dpf filter now has a visual check. ie they look to see it hasn't been removed. I will just knock the insides out. But leave the casing there.
If you want any decent mpg stay well away from an X5 lol
I got a 3.0d and expected at least 25mpg but when I got it the clock showed 19!
It needs a couple of little bits doing but doubt that will get much better.
Even on the Mway at 65 I only saw 26 briefly!
