Irritating wind whistle

[fatboydel]

First time I have been on a run since getting my new to me E Class estate, 2019 plate. Once I get above 75 mph there is a really loud whistling wind noise, is this common on this model?

I can’t seem to figure out where it is coming from but it sure is annoying.

My old c class estate never had any issues.

My W213 was as quiet as quiet. Are all the windows fully closed. Are the wipers correctly parked? Any roof bars?

Could it be coming through the vents? Mess around with fan speed and adjust vents.

 

[fatboydel]

Windows all shut, no roof bars or anything attached. Wipers are parked properly, below the bonnet line.

I tried fiddling with the vents but no difference.

Not that kind of whistle, feels like it is around the screen. Will try it with the pan roof open next time I get a chance.

Put some tape around the windscreen rubber surround. See if that is lifting and whistling

Ok thx, will give I a try.

Am wondering if it's had a windscreen replacement, and it's not been seated / sealed correctly...?

 

[fatboydel]

Don’t think so, not sure how to check, it’s not very old but I am the second owner. How could I tell?

Does the windscreen have a signature in the drivers side bottom? If so it’s an original screen

 

[fatboydel]

Yes it does, saw it the other day, thought it was a bit odd.

When I first got my E Class, now departed, I too had a frustrating whistling sound, somewhere around my right ear though. It actually sounded like it was coming through the B Post which, in hindsight, in possibly was...

I did some messing with the rear heater switches which were all set to maximum and this seemed to cure it.

Sounds like a dealer warranty job.
I would tape around the front grill see if this stops the noise then let the dealer fix it.

 

[fatboydel]

Yes, I will book it in to be looked at.

Try dropping your drivers window and then closing it again. They sometimes drop fractionally allowing a small gap which whistles.

Just found this thread and I have a similar problem.
Brand new CLA 250 picked up from the dealer on Friday morning and journey home was about 25 miles most of it motorway/dual carriageway.
As soon as the speed rises above 50mph I start to hear a constant whistling noise coming from around the windscreen somewhere. The noise remains until speed drops back below 50mph.
This is the very first time I have experienced this with any car, so it definitely shouldn't be happening.
I phoned the dealer when I got home and car is booked in for Monday 6th July......but I already have a sinking feeling that they will not be able to fix it.
