Good morning guys,

we own a MY2020 GT Premium, great car, a lot of fun.

But, we have a big problem with the noise between 1500 - 2500 rpm.



There is a noise or rattling on the driver side, omg...

We done a lot of things already (nothing worked):

- Door panel removed and insulated
- Weatherstrip removed and the plate under it, tighten the srews under it
- Stones between door and Front removed
- Exterior mirror mask off
- Side stripe and wheel arch checked
- A and C Pillar removed

We are hopeless...

Thanks for help.

Best regards,
Birdmaster
Hello I just saw this old post of yours,
Could you help me out and direct me to where you found step by step instructions of how you did the following? I believe I may have a buzzing or something loose that sounds like it's coming from the top of the driver side door, basically near the seat belt holder or above the window near the ceiling and I have a feeling it's something loose in the weatherstrip area.

- Weatherstrip removed and the plate under it, tighten the screws under it

Hello Andreas!

Weatherstrip removed and the plate under it, tighten the screws under it

I was actually referring to how you checked the pins/screws under the weatherstrip as I think my particular buzzing issue may actually be coming from that area. I saw that you checked this early on in your search for your rattle and wanted some info on how you removed the weatherstrip, the plate under it, and then checked for loose screws. I can't seem to find a step by step for removing and putting back that area. Thanks in advance :)

Also in regards to your particular rattle, how did you address the pressure line you found by the exhaust that was causing it?

Thank you all!

After 12 months of noise when accelerating, we solved it.

A guy in our german Mustang forum had a similar noise.

On the driver side, near to the exhaust pipe a pressure line sometimes touched the body of the car.

You can see the pressure line on the pic over the heatshield going down to the bottom of the pic.

We hope it works for other Mustang drivers too.

Best regards from good old Germany ;-)

What did you do with the pressure line once you found out it was causing the noise?

We pushed the line a little to the side with our hands. There is a holder into which the line can be pressed, but this also made a slight noise. Just pushed to the side.
Nothing more after one year of noise.

Best regards from Germany, Birdmaster
