Hey everyone. Just curious if anyone has experienced a "growl" or "vibration" type noise with their ecodiesel. Is this a symptom of the fuel pump failure? Or something else? Dealer has been no help, even though the sound developed after they replaced my water pump for the 2nd time. I know diesels are "noisy", but this sound is off. My wife is the one who drives it every day, as I have a company vehicle. Any thoughts are appreciated. Inlove this truck and would hate to lose it to inept dealerships who "cant find anything". 2016 crewcab with 273,xxx kms.
