Will the Skoda Octavia TDI's DPF regenerate over a 14-mile run?

I currently have a pre-DPF Skoda Octavia TDI Estate and am very pleased with it. I would like to buy a new one early next year but want to check a few facts about the DPF. The sales brochure says it should be regenerated by driving at 37mph+ (this is about 1700rpm). Is the regeneration solely linked to the rpm, because it could easily be achieved in third gear at 30mph. Once started, is the regeneration self-sustaining until completion? I do two or three short journeys a week plus at least one of 14 miles each way.

Given your regime, the 14-mile run should balance the shorter runs. High revs alone doesn't regenerate the DPF. It needs constant revs to generate the right constant temperature and it stops if you switch off the engine mid-regeneration. If this is all too much fuss get an EA211 1.2TSI 105 or a 1.4TSI 122.
