Sept 2004 jeep cherokee 2.8 crd, scan tool not known, done by garage
thankyou for the info, so probably best to go to jeep dealer then ?Also I have read up in manual that I have it maybe catylitic convertor, but not to change it before proper diagnostic test is done ?
Thanks for your help Greg
HiYou may have a DPF i believe ? which is like a Cat ,This can be cleaned out with the diagnostic dealer scan tool , this could in fact be your problem ..But yes do the diagnostic test first to confirm what problem you have .Rgds Greg
