M340i whistling sun roof?

LVm340i · 02-26-2020, 06:24 PM

Whistling sun roof when open and driving(obviously). Anyone else having this? Any fix? Should I just take it in to dealer?

No, but I have a creaking sunroof.

Yup. Have this same issue. I think it's only noticeable when it's angled up. When it's open all the way it doesn't seem to be as bad.

Reset your sunroof ...
close it all the way
Push vent again but hold it this time for 30sec most say 15but I held it for longer before it reset . It'll vent but keep holding it till the sun roof slides open then closed again.

The only whistle I'm hearing is the turbo. Very high pitched. Never noticed it before.

Yes, BMWs are the only cars that I have owned that have had creaking moonroofs - can anybody explain this?

Annoying as fuck ain't it? Have the same thing when its cracked open, and when its completely opened the wind noise is pretty bad at high speeds.

My 3IS Lexus never had ANY noises with the sunroof. Did BMW just overlook this or something?

Mine leaks in the touchless car wash. Didn't do it before but like the last 3 times, a little bit of water comes in!

That definitely shouldn't be happening. You need to take that into the dealer for them to address and fix.

Is a whistling turbo not normal?
