Diesel Particulate Filter

fergie128 · 2 Jul 2014 at 11:08

Just had a dash message on my Insignia saying that the Particulate Filter is full and to refer to the owners manual. No other warning lights on the dashboard currently.

The manual suggests going a drive and keeping the engine over 2k RPM. Just wondered if anyone else has had this kind of problem crop up in their car? Did going a harder drive fix it?

Strangely this is the first time I have ever had this come up. However, I do a lot less miles nowadays than I used to, and I am starting to think this might become a recurring issue as I am driving a diesel only about 12 miles a day, whereas before I could be doing Glasgow-Leeds return journeys twice a month.

Should I also be thinking about getting rid of the diesel and getting myself a petrol car?

Thanks!

Would it be worth considering having the Insignia remapped and the DPF removed?

I'll go and do that.

When I drive in general I never really seem to cruise at over 2k rpm. On the motorways I am usually just under 2k in 6th gear. Does driving in such a way cause the filter to clog up more and not burn off because the engine is not being worked as hard?

Well I guess I won't be having it removed then!

I'll try to adjust my driving habits so that I push the engine just that little bit harder on the road.

Something is telling me it might be time to buy that new 3 series I keep promising myself

Bought the Insignia initially as it was reasonably priced, spacious and a decent MPG. As I said, I was doing between 1.5k-2.0k miles a month up and down the M74, M6 and M1. Only in the past 3 months have I stopped this and now I do maybe about 120 miles a week max.

I'm going to pop some of this in the tank as well and take it a blast up the motorway tonight. I've read that it works wonders.

God will surely strike me down for buying from Halfords though...

So I went for a drive down the motorway on Wednesday evening, kept about 2.5k revs in 5th gear and the error message cleared after about 5 miles. Did a 40 mile round trip overall and it now seems to be absolutely fine. Actually the car sounds a lot better than it did earlier in the week
