Hey everyone, just registered to chip in with my experience on my 2021 330e xDrive Touring with Adaptive suspension. Normal brakes, no upgrades.
Same problem here. Funnily enough, mine's going in again for them to have a look.
• Only when cold, and below ~8°C (46F). Anything above, it appears to go away
• Goes away after going over one or two speed humps
• Sounds metallic, but could be rubber creaking
The "problem" developed after 6 months. They replaced some worn bushes in December 2023, but that didn't solve the problem. It's just over two years old, with 21k km/13k miles, and not abused.
My operating theory is the dust covers (sorry, I don't know if this is the correct term) for the active suspensions rubber is settling/moving into position and creaking. I was going to ask them if they could try putting some silicon spray on the interface between various moving bits to see if it helps.
Interesting that it's three 330e's that are suffering
