Sounds like it could be a fuelling issue as in a cylinder is being starved or something of the like - or there's pre-detonation which is pretty unusual for a diesel from what I understand.
It could also be the grade of the diesel used. I've been talking to some guys up here at Hotham and I've heard that the new VW diesels don't need the alpine mix due to a cold weather climate system that heats the fuel and that the diesel is so high pressured that a very fine mist is the result in the cylinder thus not needing the alpine mix or additives.
On the other side of the coin I've also heard reports that the trusty old mechanical diesels have been having issues with the new diesels - not running properly, hard starting, poor economy. Apparently it's due to the new diesel mixes that are now coming through our pumps in the last couple of years...
I think subaru need to be looking for several issues that combined are giving the results we've been reading about in this thread. One thing might sometimes be the issue, but more likely than not it will be several - specially with new engine designs.
I'll stick with the tried and tested older subi's. All the best to you all with subaru fixing the issue, they will get there. Hopefully sooner rather than later!
