2014 Seneca

[John&mel]

I have a 2014 Seneca, when I get up to 1300-2200 rpm I have a Whistling sound sounds like a fan belt but I think it’s a turbo is there anything you can do about this thank you in advance

Question: Are you in the highest gear when this noise happens? In over-drive there is a linkage whistle that has been addressed by Cummins. Formerly a recall; probably on you now.

I would call the turbo more of a whining sound. I really only hear it when accelerating hard at higher speeds. I would check the cables as mentioned

Whistling can also be caused by the screw holes on the side mirror screw holes on the mounts. You will find posts here about that. Is the sound constant or is it RPM or speed dependent?
