i read that the dpf regenerates itself every 500 or so miles.
and that it does this if you keep the revs over 2000rpm, and stay at that speed. until the whole process is complete.
you will know that the engine has gone into regen because the revs will rev higher, kind of like if u drop gear.
now i was told that it does it every 500 or so miles.
ive done way over 500 mils, and tried a number of times to get the car to do the dpf sef reg, with no luck.
is there anything u need to specifically do, ie-am i missing anything ?
p.s. my car is a 2005 530 d, msport.
