Accessory Drive Belt Part Numbers
OEM: 6K2449 Continental BELT-MULTI RIB
Same size US alternatives: K060962
I was able to grab a Gates Micro-V K060962 from O'Reillys on the way home from work, exact same size, perfect fit, and no more noise. My old belt was in bad shape, had been through a failed and wobly crank pulley as well.
Any ways, just tossing this info here in case any one searches in the future.

But for reference the factory contitech belt length is 2449mm. Gates lists the K060962 effective length at 2446 and outside circumference as 2460mm, and the K060966 effective length is 2454 and outside circumference of 2468mm. So the K060962 is technically closer in length lol. I'm sure the one you mentioned will work great but probably not accurate to say it's the "correct" one implying the one I listed is not.
I agree with you that a small difference in the size doesn’t make much of on issue. Most members here for example upgrade to a Gates Green Supercharger Belt K080505HD whereas the Gates website recommends K080507 (for stock cars).
