Hi Kmart, I live in Poland and I have the same noise and exactly on revs range that you provided.
I asked the service and I've got an info that it's sound of direct injectors.
Indeed it's quite laud sound, and it takes a time to get used to it. It's probably not optimal sound isolation.
Hi. The sound is sometimes loud, sometimes very low, and eveen totaly gone sometimes. Usually the sound only appears above 1500 rpm, but sometimes it is present at below 1500. This should not be the case if it was the injectors. Then the sound shuld be constant.
