Are the current faults the highlighted ones?

No, ignore the highlighting. That was unintentional, from copy/pasting stuff. I'm just concerned with sorting the main issues of the CEL, DSC warning, and there's also something causing draw on the electrical system, because the battery will go dead if I don't keep it on a trickle charger. Anything else I'm not really worried about.

I've got a bunch of fault codes on my E90 that I recently bought, and I need some help diagnosing what's wrong with it.

Some of the codes are related to low voltage from the bad battery that was in it, so you can disregard those. The battery has been replaced.

I'm mainly interested in clearing the check engine light and the DSC warning that keeps coming up on the centre screen.

Here are the codes, divided into each vehicle system. Any assistance or advice you can offer is greatly appreciated.

-Engine Control Module

2E81 Electrical coolant pump, speed deviation

2A2F Mixture control 2

2DEC Power management, battery monitoring

CDAD Message error (request, wheel torque, drive train, BF)

-EGS Transmission Control

51AD No message from Dynamic Stability Control

CF2B No message from longitudinal dynamics management

- LDM Longitudinal Dynamics Management

62CE Overvoltage fault

- DSC Dynamic Stability Control

5DE2 Brake-pad wear: brake pads, front axle [Could this be causing my DSC warning message on the centre screen?]

5DF4 System voltage too low

D373 No message (SZL C8, C9)

D35B No message (LDM 213)

9C6C Supply, switch centre, centre console 12 V

9C50 Rear compartment stratification flap motor

9C4B Defrosting flap motor

- CCC-GW Gateway

A179 Control-unit fault

I found a loose connector in my battery compartment. Does anyone know where it's supposed to connect to?

I'm looking for a pair of 8.5" wide Style 162 wheels for my E90 330i, so I can run a 255 square tyre setup.

I need a beige driver's floor mat for my E90 330i. It doesn't have to be from an E90 specifically, as long as it will fit. A set of front floor mats would also work. Preferably in Auckland.  Cheers.
