Another trick is to pre heat the engine during the winter, as most deposits form whilst the engine is warming up. So if you can get a cable to the car, then a simple sump heater will reduce the warm up time by about half. A full coolant pre heater is more expensive and complex to install.
If the EGR valve is clogged up, it can also cause the DPF to foul up faster than normal.
This article from the AA is worth reading if you want to know why I did not buy a Volvo with a DPF:

The combination of DPF rated low ash engine oils (They contain less Zinc based anti wear additives than normal) and fuel contamination from the Regen cycles is not a good one, as it increases main block wear factors. Changing the oil more often and using an x/40 rather than an x/30 helps, although the AA are correct to point out that DPF units are problematic if you only do short trips. Using an oil additive like Ceratec and a high mileage oil (Or a stop leak additive) can help reduce oil consumption if the block is worn and that will help extend the life of the DPF, by reducing ash deposits.

I also have a C30 1.6 d 107000 on the clock. Had the fluid done about 80000 miles ago. It went in to limp mode a few months later. So had a full dpf and carbon clean along with new fuel filter. Been fine for about 6 months today went back in to limp mode.
Getting very frustrated.and expensive.
Now worried the garage did not re set the software when they replaced the fluid.
No warning lights on at the moment though very strange
