Just for reference, though, nothing failed on you, did it?I was going to delete it after the 100,000 mile warranty ran out because of all the problems i was reading about on these diesels. Was going to keep it as a daily driver instead of purchasing a new one every 5-6 years. Our government in there infinate wisdom has created a monster with these cars and trucks. A very close friend of mine had a 2013 duramax bought back (lemon law) because it would not drive more than 500 miles without going into countdown mode. 13 sensors in the exhaust alone. Had it in for service 6-7 times and G.M. could not fix it. He lost about 10K in 1 year. If I could of deleted it I would of kept it, just not taking that chance. Too many dam sensors that fail leaving you stranded.
