So let's solve that problem as I went through the very same issue with my dad's car (a euro version 325d) and discovered my 35d (US) was traveling down that route..
I start by saying I don't know the history of yours so something unique may have happened which makes what I am about to say not applicable.
The primary reason why the DPF fails is because the car doesn't regen. And with BMWs the primary reason why the car doesn't regen is because the thermostat fails and does not allow the engine to stay at the operating temperature required for a regen to carry out.
Let me ask you something:
1) Are you having issues with glow plugs also?
2) Do you have a 480A code stored?
If so read this:
2006 E91 330d DPF warning Woes. You'll see my contribution in the last post: from that point on my dad's 325d has been fine.
I did check the thermostat in my 35d and it was indeed on it's way out. Here's the post:

Let me know!!!
DPF do not clogged just like catalytic converters do not just die
unless there is an underlying problem
