2. When measuring the battery with the engine on, the battery is on 14.2v (charging state from what i have read, meaning the alternator works). But after driving the car, turning the engine off and turning the ignition on. The battery low warning comes on in like 5 minutes. (already replaced and coded battery with a new one so it isn't that)

Seems I have to keep trying to find the problem with pulling fuses then.
Measure the voltage with a meter as well. It should be around 12.5-12.8 at rest. If it is, there's something else going on and likely isn't the battery.
