Ok - so Volvo UK are not interested in the fact that I have excessive road noise and have recorded over 80 dBA in the car.
As I cannot afford a change in vehicle (which i considered) I will go it alone with some DIY soundproofing and am looking for some help. I plan to start with the wheel arches and any then bare metal in the boot. Any other ideas will be greatly appreciated.

Hi, do you think it is structure or airborne noise?
I personally think with my 2014 V40 R-Design road noise is very good, as good if not better than its German competitors, my v40 is fitted with 17" Pirelli P7 Cinturato.
The only noise issue I have which I consider poor and requires further improvement is the cold start up of diesel clatter and a high frequency sound like an ancillary belt which soon goes away, I think this maybe a normal op for the vehicle yet annoying.
You can do all sorts but unless you know the answer to Structure or Airbourne you could be wasting your time.
Where is the noise? from Back / Front of vehicle I would probably guess rear, if you run 18" Tyre and wheel combination then you would have to expect higher road noise than the 17" because of the profile and tread etc. don't forget technically the tyre is generating compressed air as it tries to flow thru the tread blocks.
Are you running the tyre pressures on ECO or Standard pressures.
Could also be as simple as production misbuild e.g door seal under door not clipped into body or door correctly causing noise to enter vehicle.
