Yes-even on my 240D I could feel the loss of power-esp. under load. (Imagine that.) I have also been able to see the little black flecks in the clear inline filters-less so in the translucent ones. On my 300D 2.5t it started to miss at speed-just before the turbo kicked on. Marshall is right-change as needed-but I carry some spares in the trunk of both of mine. Dwight
