That clicking noise you hear could be a universal joint going bad. Knowing how fast you drive, maybe you shouldn't drive it until its fixed. You don't want a half shaft coming off.

This is why I plan to go to the dealer this Wednesday. At slightly over 7000 km and no serious track racing, this would be quite a shocker for me. I still think the noise is related to the AWS though.

Sorry to hear about this potential serious problem.  Keep us posted about dealer diagnosis.
