I must be doing something right as driven car for some 2000 miles now since purchase in Dec and never had the light come on. I do however live mile and half off dual carriageway; Norwich bypass A47 being one way and Thetford the other with one roundabout so engine does warm up nicely. I do often do long runs as well i.e Manchester and back in day 560 miles at constant 70 -75 in cruise. Oddly it was due to dpf problems why I sold my Saab 9-3 TTiD estate which are renowned for being good - mine must have had underlying issue but so far no DPF light and I always use Shell fuel (2 garages pretty close to me so why not).

Long time since Ive been on here but have now got the dpf light on and previous drives do not clear it this time. Now MIL light has joined it... am I heading for a problem or can I still fix it by driving steady for a while?
DPF additive has not helped and have just filled up with BP Ultimate at 143.9 per lit. - ouch!
That has not cleared it either...
Any further advice? EGR valve?
Cheers
K ;)

Not long after buying my T31 last August, I had the DPF light come on followed fairly soon after by the EML. Driving as recommended didn't clear it, so I took it to my local garage for a forced-regen. Got it back running fine with no lights on. It has come on a few times since, but each time a run of 20 - 30 minutes continuous at 50 - 60mph keeping the revs over 2,000 has cleared it. Being an automatic, unless driven hard it tends to keep the revs low which makes it a nice quiet drive, but to do a regen I find that I have to put it in manual mode to keep the revs over 2,000rpm.

I am inclined to think that once the EML comes on too it is time for a forced-regen, but if you can take it for a continuous run as I described above before the EML comes on, it should clear. I may however be wrong as I'm no expert, I'm just going by my own experiences as this is the first vehicle I have owned that has had a DPF.

It feels like it has done a regen as its not stinking hot and the mpg has recovered to mid 30's from the low 20's. All running and feeling fine, but of course the two lights are still on. My OBD2 reader wont read anything cannot connect to vehicle... im sure it has in the past.
So do I need to have a forced regen now then and at what cost? Do you think an independant could do it or is it a Dealership job? Nearest one is ***** miles away

If your egr valve is not shutting fully (it should as the ECU shuts it down to be able to regen), then there is no enough oxygen to burn the soot out. The cleaning map will then just make it worse.

As a short term fix, could I temporarily blank the egr to simulate a fully closed egr valve? I am assuming here that my normal drive did not clear the dpf light due to an egr valve not fully closing per your post due to soot build up. I dont want to try to remove the egr to clean it during the Christmas holidays but can see the flexi pipe of the egr would be pretty easy to access and blank off temporarily until I have more time to clean it properly.
Or is it too late now anyway now the MIL has also come on?

Are there any telltales on the Xtrail to say it's regenerating?
Had a Pug 407 before and the heated mirrors used to heat up when it was regenerating. Owners wired a small LED across power to heating element which would glow when regenerating.

Bu99er it, its parked up until after the fat mans visit then I will look at it again. Fairly resigned to a Nissan rip off regen charge but not to a replacement dpf.
Will take it to local indy to see if they can help... shy bairns get nowt.
Merry Christmas everybody

Yes, it stinks like a burning clutch or brake and fuel consumption doubles.
No visual indication, just the dash light when it fails
