Hello everyone,

We have our M40i since July and since December we're noticing weird squeaking noises coming from the back (like if it comes from rear axle, but it's very noticiable inside). I've heard rattling in multiple cars coming from different sources, but this one is something totaly different. It sounds like if there is a squirrel hidden in the back... It doesn't really come when going over bumps, bad road or anything like that. It's totally unpredictable, almost like if there's some servo moving and actually cannot move.

Nope, we don't mistreat any squirrels (or at least I'm not aware of it)

I have this happening to. when the windows are down I can hear it more after I depress the accelerator.
