Glad to hear that you got it sorted out. I know injector seals become an issue on these engines but that is usually around the 100-120,000km mark, so with your car having significantly less km's that this, I didn't expect this would be the issue. Faulty injectors themselves are much less common but obviously does happen still - and the injectors are expensive (around $700 AUD each). Did you replace all of them or just the faulty one?
So with any injector or injector seal issue, the engine will be overfuelling to try and compensate, and obviously it was overfuelling quite a bit in your instance as it was causing your DPF to get full after only 40km or so. Your fuel economy must have been really bad due to the overfuelling.
Anyway, glad it is fixed as I am sure you are also.

Injector seals & copper washers were intact, I decided to replace all 6 which paid off. The original injectors show no obvious sign of failure, apart from extremely sooty tips. I shall have them analyzed and then cleaned to try to determine if any or all are defect or out of spec.
Strangely I had no negative symptoms other than the over fueling/smoke. the mileage wasn't noticeably affected and performance was normal, hence why i had no suspicion that the injectors were the culprit. You live and learn...Thanks for your Interest.
