Hi all.
I am really hoping some in the community can help try to diagnose a really strange increase in road noise that I’m getting, shortly after having a replacement heater box fitted in my A3 convertible (a major dash-out job!)
Describing it is difficult but I’ll try. Not as deep as normal tyre noise, not as high as a whistle from wing mirrors. Somewhere in between and it’s a wind-like hum sound.
It’s just noticeable at around 15mph, nicely audible over 30, and doesn’t change pitch with speed - and although always present it will be far worse on rough/concrete roads and much quieter on smooth tarmac especially at higher speeds.
It only comes from drivers side somewhere - I have sat in the passenger seat on Audi test drives and I can’t hear a thing, yet it’s so audible on the drivers side (and as you guessed Audi can’t hear a thing).
Causes? I’ve been concerned it was work associated with the heater box but it’s been checked, is properly sealed and in any case does not extend towards the drivers side.
Tyres are relatively cheap Barum 235/35/19s and sawtoothed to an extent, but thought most tyre noise was in the lower range.
It’s not wind noise coming into the cabin as even at 70 it can be relatively quiet.
I’m sure the clue is with the tyres due to the road surface variations, but why it’s started happening, and why it’s so high pitched is a mystery - maybe the brand doesn’t suit the car and they’re wearing unevenly more each day. And also how it’s getting in to the cabin - via the wheel well perhaps?
Thanks for any suggestions you may have - my first course of action would be to change tyres, but there’s 6mm still on them so pretty reluctant to.
(I’m considering getting another opinion from an independent specialist -Audi are already aware there’s been £1,500 worth of warranty work on the car already, and a probably sick of seeing it!)
