I am noticing an odor of exhaust gases in my cab when I remote start the truck and warm it up when it's cold out. Never had a problem in the summer time. Truck only has 10,000 miles on it and I'm worried? First diesel truck purchase. Can anyone help..
I'd say it's the vent sucking in the tailpipe exhaust due to wind direction before it's a cracked downpipe. Next time make sure the vent system is on RECIRCULATE and see that helps. If you really want to see if there is a leak just pop the hood and use your nose.
Pretty doubtful it's any sort of under hood piping.
