Have you tried driving the car on a motorway at around 70-80mph at 3-4k rpm for about 15mins?
A dpf is just a filter, if it doesn't get up to temp very often it can't regenerate which is just burning all the residue left on it, and it will clog up.
Doesn't mean your cars fucked or the engines gone. Many companies clean dpf's to rid the soot and crap accumulated on it, you can buy 2nd hand dpf's, companies provide them on an exchange basis, or if you know a mot friendly garage you can even remove the dpf completely and it wont affect the vehicle negatively at all.

When I first got my car after a few months one of the sensors went in my DPF(there’s 3 I’ve been told in my cars system) and one of the reasons they said it could be is because I’m driving in to high a gear. I said I probably had been as I’d be putting it in 6th when doing 40mph.
Since then and what they recommended is if you’re doing 30, keep it in 3rd, 40, 4th and so on. I have a 2l tdi bluemotion Passat and driving like that since still gives me 800mile plus from a full tank so it makes no difference to economy which I thought it might do.
Like Kadafi said, your car needs to regenerate which takes time and needs heat. You can sometimes tell if your car’s trying to do it after a short journey becasue your fan will still be running when you turn the engine off(what I’ve been told, not in to cars at all and hate driving).

Fully understand all of the above and have done my fair share of research as this has been a persistent problem - car keeps going into limited performance mode then sometimes, at random, decides it's no longer in limp mode. Tried running at 3k revs on motorway etc. and didn't make any difference. Had it in and out of the garage a few times & a few parts replaced (EGR valve, DPF recycled etc.) before taking on the chin that DPF's don't last forever and this one is dead as disco.
It's an old car now and just sits on the drive (I cycle to work most days) as bought the missus a new car but would be a shame to get rid of it as when it's firing on all cylinders it's a great drive and when new was top of the range with all the gizmo's you don't really need but secretly want.

Good to see that it's not just me on the fence about these filters etc. I will list the X5 on eBay and wait for the right offer, I'm in no hurry to sell it as I love driving it. I won't see the diesel economy on it with such little driving but that doesnt bother me, it's the bigger bills in the future that make me want to move it on before it happens
