Hi all - So I feel like the boogyman is beginning to rear his ugly head and my 2012 328i has developed a whine that really stood out to me today while I was driving home from work. I checked my timing chain visually for any signs of scoring or wear and the chain looks brand new. I've always been a bit paranoid about the timing chain going on this car and have religiously done oil changes every 7500KM, however I'm thinking that was wasted money as I'm feeling some what certain the car is on its way to an inevitable end. I'm hoping to reach out to those of you with N20 motors in 28i cars (x3 28i 328i 528i) & if you guys can chime in if this has been a familiar sound prior to your engines, well, exploding. The video attached is of my car after it had 30 minutes to cool post drive home.

The pitch doesn't sound high enough to be timing chain.
