Thanks guys! I read that diesels will do this but I guess I had in my mind more of a mechanical pump sound. Speaking of DEF....I've put right at 1k miles on the truck since I've had it. The DEF gauge hasn't budged. I happened to find a business card in the truck when it was delivered from Texas and turns out it was a Nissan Corporate lease to a NMAC employee. I reached out to her about the truck and she told me the sensor had to be replaced. I guess my question is, should I still be showing a full tank after 1k miles? No towing, highway commute about 60 miles RT. Once again....thanks & Happy Fathers Day to all the dads out there!
