Weird electrical noise rear end (VIDEO)

[shqko]

Hi all, apologies if I’m dumb but I have this electronic buzzing at the rear bumper. I thought it was the fuel pump maybe and itd been parked for 3 hours still making that noise. My battery only lasted 6 months but I think it’s bc I had my Ecutek dongle plugged into the OBD port constantly (I know mistake). I replaced the battery today and I get the start engine battery management warning (I also had this warning with the old battery everytime I went to start the car). I reprogrammed the battery and it seems like it’s still draining. Is there something that is just passing over my head? I’m not stock whatsoever and the battery is a

Duralast Platinum AGM Battery BCI Group
Size 95R 950 CCA H9-AGM

The noise might not be the culprit but I hear even when the car is on.

sounds like fuel pump. Do you have an upgraded LPFP?

That warning you are getting is something is being parasitic and drawing energy.

I bet either the relay or the Motiv Reflex is wired to constant power

It’s my relay. I unplugged it and the noise went away. The trigger wire from the relay is plugged into the MOTIV. I’m going to put a diode on it and see if that works if not then my question is why didn’t he tap the trigger wire into the fuse box to a IGN-ON power source. Am I missing something? Will it not perform as well?
