Hiya, hoping for a bit of advice....


I've just bought a 2015 allroad with 100k miles, it has fash with the gearbox oil having been changed twice the last time being just before 80k iirc.

I noticed the other day when I happened to be driving it from cold going up a hill that hall walls on both sides and with the windows open, that there is a definite rattling sound that also has at times a sound like the old card in the spokes of a bike. It quietens down once upto temperature but I have driven for 5or 6 miles and the noise is still there.
When driving slowly and parked I've had the car in neutral and revved it and can't hear the same noise.

The car was bought from an independent garage with a 3 month warranty.

Does anyone have any experiences of this?
