How often should my DPF need regeneration?

How often should DPF regeneration occur? I bought a new Vauxhall Corsa in November 2012, 2 days after having the car and only driving about 10miles the DPF light came on. Most of my journeys are short, say nine miles, clear roads, but I do longer motorway driving three days a week.

My problem is that the light now comes on every second day. I take it for a long drive on the motorway, driving in a lower gear at 2000 revs until the light goes out, thinking I've cleared it but the light continues to come on.

If this is a 1.3 they have had problems with the fuelling to regenerate the DPF, shared with the FIAT 500 Multijet. Not hugely widspread, but some cars have had problems.

Solid and decently equipped. Reasonable handling and some frugal engines.
