Hi Azan/All,
I just wondering if your wind noise issue already resolved. Got my new 520 last Nov. 2016 from AB. Noticed the wind noise after few days later while driving more than 100km/hr. It's kind annoyed sound. Sent to BMW twice, but the respond was not so good. The service advisor advised me just to leave with it. I'm now feel very disappointed with the car. Any solution pls reply. Thanks!
