Correct.
The original Regen cycle was every 10,000 miles but only at sustained speeds of 60mph+, ie only on a motorway run. Obviously not everyone does motorway driving and stop-start around town fills up the DPF much quicker.
The updated cycle is every 3000 miles at speeds over 30mph, so should reduce dramatically the number of DPF-related problems they have to deal with. AFAIK everyone who has the latest software had no issues with tuning boxes any more.
Remaps will include even more frequent DPF regen cycles to compensate for the extra fuelling (trust me, I know
) but the Vx update seems to work fine for everyone else.
