Was up guys I have a loud high pitched whistling sound coming from engine bay on hot days over 100 only while applying half to wot it's quite loud with window down and with it up it sounds like it's coming from glove box area/turbo area have to check if it does it with a.c. off on another hot day on nicer days under 100 smashing through canyons I hear nothing even with a.c. on just wondering if anyone has any clues or thoughts on what it is thanks
