Whenever my Excursion is parked or sitting at a stoplight with the A/C (or heater) on, I smell a faint odor of Diesel exhaust inside the cabin. Once I am moving, the smell goes away. I took it to my dealer, who kept it for a day and said they couldn't find anything wrong. I also asked a technician at Wal-Mart, who told me that its common for the turbo pop-off valve (wastegate?) to release a little exhaust backpressure periodically while a vehicle is idleing. The exhaust is released under the hood which is probably recirculating through my heater intake. Could this be true, or is this smell probably coming from a leak somewhere? Has anyone else had this problem, and if so, can it be corrected?
Have you had your fuel filter replaced recently? I know when I did it for the first time, I didn't get the lid tight enough. What a mess, fuel sprayed every where. Even sprayed into the cabin fresh air intake. Took forever to flush that out of there. Wife was not happy with it. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Which setting do you have the A/C controls on? Keep in mind that the A/C setting gets outside/fresh air the MAX A/C setting recirculates the air inside the vehicle. You can change the temperature to heat or cool as necessary while using the A/C or MAX A/C settings.
Just remember that the only setting that doesn't bring in outside fresh air is the MAX A/C setting. [img]/ubbthreads/images/graemlins/smirk.gif[/img]
Note: My Ex does the exact same thing your describing when I have the a/c set for the A/C setting and the problem instantly goes away when using the MAX A/C setting....

Just remember that if you leave the AC on Max the system may develop a moldy/musty odor. To remedy this turn the AC off of max for a minute or two before shutting off the truck. That will dry it out and eliminate the moldy/musty odor.
