I checked the oil filter, as I’ve seen in other post/videos. A similar sound, but it’s all good, filter it almost OEM. Lol
thank for the post though!!!

What lead me to that was i took the drive belt off so I could see if the noise was driven by the belt.
Then I got a shorter belt to bypass the ac compressor to see if it was the alternator or not.
I got the pulley off ebay and I got a denso removal tool. Total repair was 100 but took me a week of messing with it.

Thank you so much! I’ve seemed to narrow it down to the AC pulley, I’m pretty sure because I’ve used my AC more this summer then I’ve used in the past 5 years of owning the car. Global warming is real in the desert....
Anyway I don’t have the time to diy due too (abnormal) extensive work hours this month. So I bit my tongue and got a rental car, my precious bmw sits at at bmw indie shop at the moment.
I’ll update with the final diagnosis so maybe someone else will find this post extremely useful (life saving) in the future.
Thanks again BOSS!
