MG4 Central vibration/rattle

Hi! At the end as an electric car so each sound is more clear... I want to share with you a video with a vibration/rattle which is coming from de central air flow or some area behind. I already check that is not the below conducts, the sound is very clear in the area that you can see in the video.

Only perceptible at low speed (Less than 60 KM/H)

What do you think?


I had a similar issue. My spare glasses were rattling in the central box.

The same noise I have. I usually have the music which covers it, but it's very annoying
 
ok, first of all, sorry for my english because ist't the best :). and seconds, maybe the pieces and position are different because my car isn't a UK versión.

My problem was the AC radiador and the solution was very simple, Just put two or three layers of foam.

For that, you must remove a lot of things. Glovebox, plastic cover down of glovebox, plastic cover on the left side to access to the central ac unit (mine was rigth side).

When all of those plastic are removed, you will see a big Black plastic unit, and at the botton, a Metallica box(grey), that is a high voltage radiator.

Beside, you will see a cover that are looking down, with a few torx screws, you will find it because there are two metalic tubes. Si, you must remove the screws, take of this cover, push up the radiator with your hands, and then, push a few layers of any to help to stay with the correct position.

I attach an older image with a mark where you will find the cover that you must remove. Sorry because i have no more images.

I hope this helps you, but if you need something just tell me.
OK, I'm going to try your fix. The noise is too annoying. I was able to remove the left side plastic to take a quick look and I think I've got it, knocking on the radiator I can hear exactly the noise. Next step I will remove the glove box, but then I didn't understand where did you put the foam/felt. In the picture you marked a spot, what is it?
Thank you for the help, we all appreciate it.

Hi, when you remove the left panel, you will see a metal object with orange cables. That's is the heat unit. You must remove that unit removing knots at the bottom and a lateral cover that is in front you. Now, you can take out the heat unit and on it top, I put a lot of foam.

And the image, it is just to show the heat unit and the plastic. That mark it was for another topic.

One more thing, I put foam at the top of the heat unit, but when you remove it, you will see another radiator.

That is what I think is the true problem. So, more foam :)

Hi, i attach new image..

Red X--> if I remember well, these are not necessary to remove.
1--> first you have to remove all nut at botton of this piece. That piece are the heat unit and it is joined with a radiator. So you just have to unscrew and not try to remove it in this step.
2--> when all nuts from the piece 1 are removed, now you can take out this cover named 2. This is because the piece 1 holds a little part of the piece 1.
- Now, and if I remember well, you can remove the piece 1 and the radiator. You can take it sliding towards to you throw that hole where cover 2 was.
3- these tubes, are for the another one radiator. So that one just try too push down these tubes and now you will have access to the top of that radiator.

In my case, all rattles were coming from those radiators and plastic, so with foam at the top and bottom of both radiators, all sounds dissapear.

I hope that helps you, but if you need more help or anything isn't well explained, let me know and I will try to explain in other words. :)
