I'm 720 miles into ownership and I've got my second problem. During a short evening drive my M3W developed a very loud vibrating sound. The following morning I had a chance to look for the sound and was surprised to find the bolts for the fan shroud were gone, presumably fallen out due to vibration. The missing bolts allowed the shroud over 2" of slop and caused it to rattle off the back of the motor. My dealer was super responsive and is getting me replacement bolts and spacers ASAP.

Welcome to ownership!
