Hi everyone, i am new to any forum so please excuse if the way I put things is not correct. I have just bought a 1999 2.0 Z3 it drives extremely well and I am pleased but when driving over 50 mph there is a terrible whistling noise coming from the passenger side. the hood appears in good condition no leaks etc and operates well. Could some kind person point me in the direction of how to solve this as it is most annoying.
