jon Posted June 22, 2011 Posted June 22, 2011 Pretty much every NA (naturally aspirated) 4 cylinder model from 2006 to 2010. Essentially the front air fuel sensor is not correctly reaching operational temperature early enough in the start up cycle and until it does the content of the emissions coming out of the tailpipe will be increased over the design. I do think its great when something that affects our air quality is recognized and dealt with properly such as this. http://allwheeldriveauto.com/subaru-service-program-wvu-31/ Quote
pup_on_the_mountain Posted June 24, 2011 Posted June 24, 2011 Thanks for the heads up! I got mine (2009 Outback) reprogrammed today; took about 30 minutes. Apparently, they are sending out the letters in a staggered fashion - 2006 and 2007 vehicles first, followed by 2010, then 2008, and finally, 2009. Quote
