Question about when you shut the car off..

[KnightWRXRider]

I get sort of a rattling noise, like something is settling maybe it could be air or something it's hard to describe. The dealership said it was nothing and it just was the exhaust rattling, the heat shield or something. Could that be like something loose maybe with my BOV or even something weird to do with the exhaust since my exhaust sensor is gone, I got a CEL from that, they're going to be replacing that. Basically I"m asking does anyone else get any strange noise when they shut the car off? Thanks.

Is it RIGHT when you shut your car off? And also do you know where it might be comming from?

[KnightWRXRider]

Yes it's when my engine shuts off, no I'm not entirely sure, and honestly really don't trust the dealers all that much because I think they are bunch of retards. But I'm not sure if it would have to do with my BOV but it's a recent thing like last 2 months or less.

I had a bad rattle also when I installed the Scoobysport turbo back exhaust. Found out it was hitting against the rear dif protector plate. I just took a di-grinder with a metal cutting bit and notched out the the plate.
