Hi, Thanks for your reply. Good to know the Pirelli Scorpion tyres are not to blame for the noise.
Yes it is a permanent 4 wheel drive, but I dont know what technology system it has.
The car is a 2021 year and only done 17000, and has just been serviced by Audi.
I think I will take to Audi in Hull , and let them take a look while the 30 day exchange program is still valid.
Thanks again, Charlie
