I have a kind of howling sound as i slow down at around 35 to 40 KPH. It is not constant but kind of cycles as I slow. I also notice it taking off but not above those speeds. It has been there since I got it new from the dealer. It is a 2009 RS and has 3000 KM. I had the alignment and tension checked and the dealer said it was OK. But I don't like the sound, any ideas would be appreciated.
