You still got these at all?

Indeed, It is infact bad for the longevity of your DPF (Diesel Particulate Filter) not to take your car through the rev range once every so often and they can be costly to replace. May the doctor suggest a good B-road bashing rather then the Mboring after work? :~) As above, only my humble opinion....

I (personaly) wouldnt, but Im a fidler, I fix things even when they work fine already :-D
