This sound is confusing me. Just dont get my head around it. Starting to think it may be the throttle position sensor.
Anyone knows if that part can give some sort of sucking noise?
I had that exact same sound a year ago, suddenly disapeard and now it has appeard again.
Its a 735i 02.
Thanks for taking ur time listening to it.

Sounds like a SINGER 4452 HD sewing machine with extra-high sewing speed of 1,100 stitches per minute, which means you can plow through projects 30% faster than a standard sewing machine. It's stainless steel bed plate enables smooth fabric flow and the heavy-duty interior metal frame ensures skip-free sewing.

But if it's a N62 - I'd check the CCV's for a tear and your CCV hoses first. Then I'd see if the Valvetronics and Vanos were working correctly.

Checked the ccv, its fine. I have no faults in the dme. Sounds like the sound is coming from the front somewhere. I have tried to pull the belts off, to see if the sound disapear, but didnt. Also, the sound appears first when my engine is hot

IMO it still has that air flow sucking sound. How's your CCV hose(s) & Air filter?

Air filter is about a year old. But can it really make that sound? Theres no hoses attached to my ccv. Its a closed gasked. And those are new to.

Pull the oil filler cap off while it's running and see if the noise changes
