Hello,
Had my first major issue with my S8 yesterday. I was out of town for a week and left my dash cam plugged in causing the battery to go flat. When I returned and found the low battery I charged it for an hour up to about 30%, removed the charger and started the car without issue. I let the car sit and idle for about 20 min then adjusted some of the settings that had been reset due to dead battery. Traction light was on but immediately cleared when pulling out of driveway. Drove around the block and car was great as always.
Took the car out an hour later. Everything was perfect until I went to accelerate to get on the interstate. The EPC light immediately came on and car lost all power as soon as I stepped on the throttle so I pulled over. The car would not even idle very well and wouldn't do anything more than inch forward. Throttle was non responsive. Died a few times when putting in gear. I turned the car off and on a couple of times but no change to the EPC light or condition. I ran an Auto Scan that I will copy in the bottom here. I noticed on the auto scan that the voltage recorded is in the low 11's and high 10's which is low. It appears that all of the codes seem to be related to ground issues or low voltage.
My theory is that I was adjusting the stereo right before the drive and that the battery was enough to start and drive but borderline too low to run everything once I turned on accessories that draw power and when I accelerated the battery didn't have enough voltage to run everything due to not being fully recharged yet. It's just crazy to me that 15+ codes popped up instantly so it seems it has to be related to the dead battery. Thoughts anyone?
I have a Hex V2 that I used for the auto scan. I have not made any adjustments to the car yet because I just got the V2 and have been out of town. Looking forward to using the V2 once the car is running again. Planning on trailering the car to the Audi dealer for service but would like any input that may help in my understanding to communicate with the dealer.
Thank you.
