So, I've owned my 2014 Facelifted Superb for 1 year now and I am pretty fed up with that its so god damn loud in the cabin, the road noise is killing me and I don't know what to do. 

 

Should I sound dampen the wheel arches, change tyres or just change car because as it is now me and the misses need to lean forward all the time when sitting in the back and talking to each other and it sucks. And I must add that the tarmac here in Sweden is very rough because of our climate. 

 

It is somewhat quiet on new paved roads though. 

 

What should I do? Is a Audi more quiet?

Mine is now very quiet. It had both front wheel bearings done at 55k as they were very noisy. Also now running Goodyear F1 Aysmetric 3 and these really helped. 

I found mine quite noisy when I bought it. I bought some fairly thick insulation and stuck it to the underside of my carpet mats and the boot mat. This got the noise down by a couple of decibels and was cheap to do. 

 

It's also worth having your four wheel alignment checked as that could have an effect on how the tyres wear and create noise.

 

Thirdly, check your tyres. Mis-matched brands, un-even wear or nasty budget tyres can cause extra noise.

 

Dont give up! They're good cars.

I bought a Greenline new 3 and a half years ago. The car has always been very quiet. My previous car was a mk2 VRS Octavia that I sold due to the horrendous tyre noise coming from the low profile tyres. 

It is possible that the tyres are your Achilles heel.

Good luck

I have a 2014 Facelift Superb as well and it's so dam QUIET in the cabin. The engine is quiet(it is petrol though), the road noise is quiet (even quieter now I've just fitted Michelin Crossclimates) and the wind noise is quiet. Something has to be the loudest - the heater fan seems loud and there is an occasional rattle from the front passenger seat that goes away when I'm travelling alone 

 

As previously mentioned tyres and the size of your wheels may be a major factor. Mine is also a twindoor , that possibly has less noise intruding from the rear

 

Having restored many cars and buit  a kit car in the past and if you need sound insulation that's thin , easy to apply and hardly affects the fit of carpets & trim then investigate the use of bitumen pads. Made an amazing difference on my kit car and a very noisy 948cc Morris Minor

My 2014 diesel estate is quiet - its on par with the 525d estate I had before it. My elderly Mother and Father in Law were in the back of it most of today and we chatted away normally, on motorway and poor surface country roads.

 

The only time road noise ever got intrusive was 1) when a tyre was about to go and 2) when the new tyres were put on and they droned a bit for the first few minutes of use on the motorway.

 

I'd check your tyres first, then alignment. The level of noise you describe isn't normal and you shouldn't have to be fitting insulation to have a quiet S II. 

I have a superb diesel estate. It's not bad for noise. There's a bit of a hum from the engine at motorway speeds but nothing too intrusive. My previous car was a volvo xc70 d5. It was pretty agricultural around town (the Superb wins hands down there) but very very quiet on the motorway. The superb is not quite so good at speed mixture of engine noise and road noise.

 

Recently replaced the front tyres (both punctured but with over 5mm of tread on them) with a pair of Nokian weatherproof and road noise has significantly reduced.

 

Cheers,

Has it always been noisy or is this something that has just developed?  I agree with the above comments that it might be tyres.  What tyres do you have and what size wheels do you have?  Lower profile tyres wont help with road noise, especially on rougher roads.  I presume the soundproofing is all in place and none of it has been removed for any reason, particularly around the bulkhead?

It has Goodyear Efficientgrip performance 225/40/18 (69dB) in the front and Michelin Pilot Sport 4 225/40/18 (71dB) in the rear.

The decibel readings on the tyres mean almost nothing. They are registered externally.

 

I changed from 16's to 18's. The tyres I fitted were rated 67db and were VERY noisy. This is why I went down the route of adding sound insulation to try to help.

 

From reading a lot on here the Superb doesn't like the 18's too much. I noticed a drop in MPG as well as the increased noise level. On the plus side it looks a lot better IMO.

 

The insulation I bought was very cheap, about £20 for a large roll, and did help a bit.

The road surface is the biggest contributor in my experience, and the type of tyre can make a big difference. Our previous car (Mazda 6) was very noisy inside with directional tyres (old style Eagle F1s) but bearable with Michelin Energy XM1s). Our Skoda is significantly quieter, but the difference between asphalt and coarse 'chip seal' is huge.

18 inch low profiles do have a reputation for noise regardless of the car. Watch the Youtube video where they compare 16,17 & 18 inch versions of the same tyre on the same car and they come to a similar conclusion. 

Mine did seem to get a little noisy when driving at 55-60 MPH plus.... As stated above I have just changed all the tyres for Michelin CrossClimate 225/40 R 18 tyres and the difference is unbelievable... the car is much smoother and quieter to drive now... The old tyres had done almost 20000 miles with about 3mm left on the fronts and 2mm on the rears, so maybe tyres do make a BIG difference.. 

The road surface can make quite a difference.  Mine was never very noisy except when we were driving on some concrete roads and the motorways in Belgium! 

 

I had Continentals all round when new, then Goodyear F1s on the front and Avons on the rear.  I don't like to mix tyres, but I needed a new tyre in a hurry after a puncture and took what I could get.
