Hi, I have a 2017 530i with 16,000 miles. It’s developed an odd rattle that I can’t find. It almost sounds like chirping / squeaking and can be heard at speeds as low as 15 mph on a slightly bumpy road. I put my phone in the glovebox and recorded it and the sound came through quite clear. Also did the same by putting phone in the boot and no sound showed up on the recording. The suspension does not make a sound when I bounce each wing. No abnormal noises when steering. This video has almost the exact same chirpy rattle https://youtube.com/shorts/hqnwwdcgOCo?feature=share. Any help appreciated this is driving me mad. Thanks 😊
