Nissan QashQai Forums

I found the road noise level on my QQ much higher than my previous Peugeot 3008.
Initially the problem was down to over inflated front tyres by an over zealous pre sale technician
The noise level is better but is still not good and hopefully new front tyres soon will improve it a bit further.
My question is, has anyone use Noise Killer Acoustics or a similar company that provide pre cut sound proofing panels for under the bonnet, footwells wheel arches and boot etc Around £230 for a set.

Hello have similar concern with my 2017 st QQ. Have two new tyres on front now and this has made a bit of difference the rears will be next when a little wear has taken place. Upon inspection of the wheel arches less their plastic covers to find no sealant at all only the white paint. These then got a coat of sound deadening material as did other areas of the under body. This has taken the harshness out of the noise but still present. The tyre pressures have all been set to mfs around 33psi or 2.5bars I believe. Here in new Zealand we have a mix of road surfaces from course chip to smooth asphalt and it is very obvious the sound difference from one surface to another. Have you had any luck with your noise level.

Check out some of the previous posts on noise, and reducing it but for example one area to check under the bonnet for noise is the air inlet filter ducting and it’s two part connection half way and then also where it actually joins the air filter box and the securing clip at the top of the filter box. People have reported that the plastics at the joints here become worn and so then start to vibrate. There are YouTube videos that show how to remedy this if you find this to be true in your case. I had it with mine but simply bought a new duct from Nissan Spares.
