    I hear this weird sound when breaking in slow speed. I don’t always hear the sound. I’m wondering if it could be something with the battery generation mechanism that needs to be replaced. It’s doesn’t sound like it something with the break pad/disc it’s more a low pitch sound. The car works otherwise well and I have no error codes.

    made a video with the sound with my phone on the dashboard.

    I gave it a listen and thought the OP probably meant the low-pitch wormp-worrrmp-worrrrmmmmp sound.

    I heard it, but no ideas came to me. Hadn't heard that one before.

    I think it could be something with the breaks pads/disc and heat. I drove for 10 min doing acceleration and breaking and could not here the wromp sound but then I started to here it right after 10 minutes. I check the break disc and they were normally warm. But maybe one of the pads is uneven worn.
