High speed whine/hum
Hi guys,
Recently went to Germany and experienced the autobahn and for the first time ever really stretched the legs of my 220d.
Everything was going well until I got to around 125-130mph the car started making a loud whine/droning sound almost like a pad was rubbing on the disk but louder inside the cab. Slowed down to 110-120 it went away? Crept back upto 125-130 and it comes back...
not sure it was wind noise because it didn't sound alot like wind noise...

Apologies for the delay in my reply.
I've taken a video of the noise. Doesn't sound tyre related?

Possibly, good idea to bring it back to the dealership, it is pretty common for mistakes now installing the backing plate wrong for instance.

Had everything checked that they could physically check bearings are all fine brakes are fine.
The garage is stumped. which doesnt help me at all
I'd say is it possible its wind noise? But it sounds more like metal whine so I'm not sure where to go from here.

I would also go at the brakes but test if you swivel/Drive linke drunk in an S line if while braking the noise changes then it is in the front....
Do you drive with the paddle shift once in a while? Maybe test lower gear while driving slow
Maybe if you only drive slower the engine spinning (rounds per minute) where always low for you, 7G Gearbox or 9G Gearbox keep the revs very low for fuel savings
If the belt slips or the Tensionen is weak it will whine it high revs, 100km/h+ on modern Mercedes with 7G if you only drive in town :-)

The noise is coming from the roof liner.
Did a road test with a friend who was covering vents and things whilst the noise was present.
Low and behold he pushed up on the roof liner on the passenger side and the noise stopped. Let go and it comes back. As you can see from the video the pitch of the noise the roof liner is the last place I expected it to come from. But now the question is why is the roof liner causing what I'm now guessing is a wind noise?

I don't know what to do to fix it or find the source. I can't just shove the roof liner up because it will bend/break it. May need to investigate further it could be anything... windscreen incorrectly fitted or anything
