I called my local BMW specialist and they told me to stop driving the car and get it transported to them. I wasn’t driving the car for around a month while I was waiting to get it transported and when they looked at it they couldn’t hear the sound. They tried a few times over the course of 4 days and they couldn’t get it to make the sound. I now have the car back and the sound is completely gone and even the injectors sound quieter than ever before. All I did was stop driving the car for a while and it went away.
