Have no luck removing the rear shock strut mont, it’s the only thing I can’t remove, any tips ???? Help
Check the wheel liner to make it is not loose.
Also check the weather lining around the windshield. I has a E60 BMW that was driving me crazy. It had the same nosie you describe. After checking everything, including for loose parts by the bumper, it turned out that the rubber strip around the windshield was loose.
As we started to drive it would flap and make noise.
Would love to know what the problem is in your case.
I would check the linners in the wheel well. Also check the splash shield under the engine. A loose one can make a similar noise.
