Started the morning off by fixing an annoying noise on my car. Not my video, but basically I am getting this exact noise under heavy acceleration and only in 1st or 2nd gear. Anything beyond that, and if I do normal gentle acceleration, there is no noise at all.
weird grinding noise coming from center console area. any ideas?Fourm on quick fix: https://f30.bimmerpost.com/forums/showthread.php?p=25553557#post25553557

It doesn't sound good, and I was lucky enough to recognise the noise from my previous F30 otherwise I would probably have been bricking it, although the circumstance there was different. In my previous F30 I drove over a deer that was already dead (couldn't avoid it) and the car started making that noise. That turned out to be the metal heatshield around the prop shaft, it was just bent in and rubbing against the prop.
This time it was a simpler and common F30 problem. The handbrake cables run directly above the prop and BMW use a plastic clip to hold them in place and these clips frequently break. The official BMW fix is to replace the cheap part with another cheap part that will likely fail again, but the biggest problem is because of the amount of labour involved (they drop the fuel tank slightly to get access to it) it costs hundreds. Though looking at it, I do wonder if it might be possible to get a small ratchet spanner in there:
Can clearly see the left cable is still clipped in but the right one is hanging down. I can't be bothered to mess around with it too much right now so I've just done the quick and easy
fix bodge:
Metal cable tie against the diff mount to just hold it up a bit. I originally had it tied in a different place which is why there's two ties but looking at it now, I don't know why I didn't remove it and just use one. Regardless, noise is now gone. Also popped a tie on the other cable to support that before the other part of the clip breaks too.
