Presumably your R is not one of the early ones, very few of which suffered with blown turbos. Personally, I would not worry too much at the moment. Try deactivating the little bugger that provides the false sound and if the squeal is still there, take it back to the dealer. It might be just how the R is and you have to accept it.
I have a 722A car is registered Sept 2014. Will try the sound actuator.
