    Electronics fault! ESP light

    Guest-only advertisement. Register or Log In now!
    My D3 A8L 4.2: ESP light and engine light came on after a hard acceleration. I have reset all codes... the fault lights are still all on after driving a while. Now I have a ton of different fault codes. I don't know where to start troubleshooting! I have noticed some performance degradation and my MMI/computer interface is malfunctioning/lagging. Sometimes dome lights turn on at unusual times... Does anyone have troubleshooting suggestions? I was thinking a voltage regulator or computer failed... idk where to start?
    Here are a few of the codes coming off the car:

    P0101 Mass are sensor flow A circuit range/performance

    01926 sensor for steering angle(g85), voltage supply terminal 30

    18265 load signal, error message from ecu

    18061 please check DTC memory of ABS ctrl. Module

    16485 mass air flow or volume air flow(g70) range/performance

    P2637 torque management feedback sig. A

    01504 bulb for licence plate light X

    18010 power supply terminal 30, low voltage

    ... Many more

    I was thinking it was battery but it starts fine... Battery is mainly just for starting, alternator takes over after that for the most part?

    The battery is a good start, testing it that is, not changing it :-)
    What is the history of the car, e.g. accidents/previous electrical issues? Also could you post the full error log ideally from VCDS?
