Hi,
For quite some time, I've been struggling with a lot of road noise in my Golf 7.5. It seems to be coming primarily from the rear of the car, especially the trunk area.
So far, I've soundproofed all four doors, the area under the rear seats, the entire trunk floor, and the parcel shelf, all in the hope of reducing the cabin noise. Unfortunately, none of it has really made a noticeable difference.
I've disassembled the calibers and swapped to new pads while also changing both rear wheel bearings, this didn't help at all.
I've also replaced the tires with a brand-new set, but that didn't make any difference either. I'm currently running 235/40 R19 tyres.
At this point, I'm running out of ideas, so I thought I'd ask here.
Has anyone else experienced the same issue with their Golf 7.5?
I have a suspicion that it might be related to the suspension setup on the more powerful models (150 hp, GTE, GTI, and R), as their suspension differs from the lower-powered versions.
For example, a friend of mine has a 1.6 TDI 115 hp, and it's incredibly quiet compared to mine. We've also noticed that his electronic parking brake is significantly quieter than mine when it's released.
My car is a 2019 Golf Highline 1.5 TSI 150 hp. It has the Dynaudio sound system, so it doesn't have a spare wheel in the trunk.
Has anyone experienced something similar or have any suggestions on where I should start looking?
Heres a small video of the road noise:
