Thing is, the stick is broken so i can’t tell how much coolant there actually is fml
but ok I dropped the battery to 80

and like I said, there’s no codes at all about coolant or the pump
but take a look at this last few codes I got from an engine malfunction.. owner before me cheaped out and kept cleaning a sensor instead of replacing it so engine malfunctions pop up every now and then until I turn the car off and back on. It here are the codes

You need new coils, spark plugs and vanos solenoids (exhaust and intake). You can try cleaning solenoids but I doubt it will work. Once you replace that change your oil and reset adaptions. Everything should clear up. Make sure codes are clear before starting the car up.

Do not go cheap out on the parts because you will not fix the problem. Purchase OE or OEM parts. You can go on pelican parts to find the parts. You know if it's OEM because it will have the same part number as the BMW part with letters at the end. Also you need a new coolant reservoir also. Any will do.

Hi
So the same day I was talking to u guys.. I ended up getting the red warning and the car basically lost all power and had to keep stopping until I managed to get home okay.. the red warning being the engine overheating one.. what’s strange is the error code I got was
2E83 - electric coolant pump, energy operation

but after parking it for a day or two, I decided to drive it again and the yellow heating up messages came up here and there.. now, I unplugged the battery for 30 mins or so, topped up on engine oil and also removed four of the coils and cleaned the little bit of oil that was spilling into the cylinders... and right now, after driving for about two hours and having the ac blasting.. I haven’t gotten any engine heat up messages at all.. instead, when I normally would hit 80+ km/h by jumping on the highway, where I’d normally get the engine heating up “yellow message”.. this time I got an engine malfunction message which reduces power only.. the error I got this time for some weird reasons was..
30FF - Turbocharger, charge-air pressure too low

as well as the normal two engine errors I’ve always gotten 29F5 & 29F4 which are catalytic-converter 1&2

but this is all starting to make me trip out now lol., could the battery I installed 2-3 weeks ago be causing all these weird things to be going off like this? Someone plz point me in the right direction.. is the water pump working extra hard/loud like this because of the battery?

You'd probably take less time by having a BMW indy mechanic diagnose it. There's only so much we can do online. BMWs are much more complex than you may realize. And you seem to have a lot of different things going on.
