Wind noise on the driver and passenger side when you get higher speeds?

[timbola]

I've found it a mission in futility and mine is there all the time at speeds over 45 mph.
I intend to use masking tape on the whole of the driver's front windows and if it's still there I'll tape the door.

I've tried masking tape around the window seals and the wind noise was still there so I tried tape around the door itself and it was still there. I'm beginning to think it's just one of those things.

Mine has always done the same, I think it is just one of the drawbacks of the MG4.

More recent models seem to be better insulated from noise.

I must admit that I haven't noticed this, I'll watch out for it next time I'm out & about

It is possible they've improved it on later models, mine is an early one. Be helpful if people could comment with their experiences.

I'll have to see if I can drive without loud music...

I don't find mine to have any excessive wind noise - certainly no more so than any previous car I've had. (Nova, Escort, Corsa, Astra, Golf, Insignia - in that order).

I noticed a noise this weekend which I believe is aero related. Comes from front of car. Starts at around 40mph to around 55mph. Key thing is it is only present when the AC is off and absent when AC on. I drove around 50mph and could reliably affect the noise by switching AC, taking a few seconds to respond so I guess that a flap is changing position. The noise is very faint and high pitched, bearable although a little annoying!
Car is a gen 2 SE LR.

Did you ever find a solution to this? I have the exact same noise you are describing, only happens with the AC off. Very annoying! Cheers

Does anyone know what the exact cause is of the 40mph whistle?

Many have speculated it's the gaps between the rear spoiler. I haven't tried taping it up yet though to confirm.

I have to revive this thread, I'm fighting the same issue

MG4 Luxury from 2024. Whistle/wind noise above 80 km/h, getting much worse at 130 km/h (Autobahn). Sometimes I can even hear it at 30 km/h when the wind hits just right.

Ask the dealer/mechanic, but just by test driving they can't localise it either. Did three runs with different tapes and haven't found the culprit yet. It doesn't sound like it's the small triangle window, but I might just tape it to be sure..

 

[timbola]

Let me know how you go.
I've given up.
I had the speakers upgraded which has blocked it out somewhat.

Not got it on my TR but a friend had it on his SE. The garage did a warranty repair and “adjusted” the hinges or something like that. Fixed it.

Hinges of what if I may ask?

Hinges of what if I may ask?

The doors.

 

[Corindikev]

Unless the panels are misaligned I can't see how the hinges that are not in the airflow with a very small gap between panels could possibly have any effect.

I think it was to adjust how the door fit.

So, even more test runs.. still haven't found it. It's not any window, door, bonnet, spoiler, mirror, ..

There are two small slits on the undertray I could see, I'll try taping them next. Just not easy to reach.

 

[NLMGSAN]

Difficult to imagine that wind noise from down there will be loud enough.

Had another mechanic have a look, he also has no idea. Thinks it's wind noise from the upper side of the windshield, but I fully taped around that and it didn't help. Also taped the opening for the temperature sensor, no dice.

Bottom tray looks fine based on the mechanic (but I didn't get a chance to tape it).

Maybe it whistles whenever the active grill is open?
