Has anyone else noticed a slight whining, fluttering-like noise when accelerating? Faint but it has an annoying tone. Seems to come from driver side but not sure it can't be heard on passenger. Thanks.

Metallic whine is a completely normal noise on 3IS 350 F-Sport. All of them have it and it is really annoying but totally healthy. Cant do anything about - it is just the way it is. Recently had a chance to drive bmw m235i and boy does it sound sweet.
