My D3 A8L 4.2: ESP light and engine light came on after a hard acceleration. I have reset codes via odb2... 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, sensor, or a 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
