Thinking about it. I would seldom do more than 20 miles continuous at full temperature. 25 is a run to Belfast up the M1.

I retract what I said about software reset. The changes were down to me using a different key fob.

Isn't "tripping" every day bad for your health? :twisted:

On a more serious note, in winter 7 miles from start is not enough to get the engine warmed up. Doing that twice a day (to work and back) is not good for a diesel.

The car needs to sit above 2000 rpm for a specific period of time (at least 20 min or so), in motion (so not in neutral thrashing it on the drive!) when the onboard systems say it is time for a regen! That bit is a minefield.
I find it quite funny that 2000rpm in 7th equates to about 81mph! This wasn't a problem when I lived in Germany, but clearly UK is a different matter. I rarely use my SD for journeys of less than an hour, but occasionally I stick it in 'Sports' mode when cruising at 70ish to force it into 6th in order to give a regen the opportunity to happen. To date I have never noticed a regen take place, but then I have never had any DPF problems.

Yes, the regen will only happen when the car deems it necessary; at that point, move the stick accross to manual and select the appropriate gear to keep 2000 rpm+.

Mind you, I did 9000 miles in my first SD without the need for a passive regen. A few long trips every couple of weeks seemed to keep the ash level down.

If the oil temp isn’t up to working temp on every trip for a good while, then you’ll be accumulating ash with all the consequences

I think that should be active regen - you won't notice the passive ones

The light will come on when the ash level has reached xx% thn Active regen will the take place providing all conditions are met
(I never saw this light)

Passive regen (as John-M correctly states above) happens without you knowing other than maybe a hot smell and higher revs.

I didn’t get any lights prior to the orange warning.

Tom, that is the most relevant point. There is no warning of an impending DPF issue. The warning a couple of posts up is shown when the DPF is almost fully clogged and you then need to find some stretch of road to force a regen. That was my exact issue with my SD. It was dictating how/where I should be driving. It all comes down to driving requirements. If you do loads of small trips yet still do 15k miles a year, a petrol is actually far better suited. If you do loads of long distance travel and get up to 15k miles a year, a diesel is better suited. Just because the mileage is high does not necessarily suit a diesel. Like you've seen above, a diesel will have substantial issues with a lot of small trips which doesn't get the engine up to temp. Worst of all, if the car identifies it needs a regen and starts it and you then switch the car off, the whole process is cancelled and needs to start again. Confucius say...with diesel come great responsibility! LOL! Hope you get it sorted though.
