M235i air hissing and buzzing sound
On my 235i I’m hearing an air hiss after light pressure on the gas that last 2-3 seconds. Also don’t hear my diverter value “woosh” until around 3500-4000 rpm’s when I use to hear it even under 2000.
Could it be a leak or connection issue somewhere? Anyone had this issue before? No noticeable loss of power also just the sound issue. There is also a strange noise just near the ending of the hiss that sounds like a buzzing. I’ve got an aftermarket forge diverter value (installed 5+ years ago) https://youtube.com/shorts/OHdrU-mNs...zTV3BjHcTldHMj |
