My particulate problem
My 2007 Hyundai Tucson CRTD CDX 07 diesel has been showing a flashing amber warning light. The handbook says "emissions system check particulate filter.” The advice given by the dealer is to run at sustained speed over 60mph for at least 30 min in order to regenerate the system. I have done this twice and had the light reset by my garage. However, the light comes back on after 15 minutes driving. The dealer says it’s due to short journeys allowing a build up of soot in the filter (I have done short journeys lately due to snowy conditions (4x4 needed). The Tucson forum site says take off filter and clean, The dealer says no need just do the long sustained speed run, or replace the filter at £2,000. The car has only done 35,000 miles. What do you advise?

It isn't sustained road speed that regenerates it. It is sustained engine speed. I guess 60 is 2,000 - 2,500rpm. So running at a sustained engine speed of 2,500 - 3,000rpm, probably in 3rd or 4th gear might get the soot burned off.
