Hi for last few months i had weird noises coming from drive belt area, specially on idle.
Was trying to find someone with same fault, but couldn't so I maybe save someone trouble here 🙂
So I made small fault finding and found out that bearing on air con compressor has gone, start making noises and slowly start locking (can smell slipping belt).
As I don't have time now to play with air con I measure belt and bypass.
Belt what's you need to do it is 7PK1378 (tested only on 220D 2AD-FHV)
when I found time and parts to fix ac I will make some step by step how to do it, maybe even on a car 😉
