Hi all, my Diesel 100 series has been parked for a bit, so I started it up today just to give her a good run, and after returning and letting it sit for an hour or so (turned off) I started hearing a weird noise under the hood. To be clear, I only noticed this noise while the vehicle was off, and parked for about 45 mins or so.... I may have to post an audio clip, but either way, I traced it to a part that is behind the passenger front wheelwell shroud directly in front of the air inlet. This is a picture of the part. As soon as I unplugged it the sound stopped. Anyone know what it is?
