Hi all,
So my A3 which I only just got has a battery drain issue. If I leave it at around 4pm and then the whole night, then in the morning the next day it feels like it's having a hard time starting. Measuring the battery voltage in the morning before starting reads 11.6V which is way too low as it should be especially as a day before it has done a 160mile trip.
I've read about the hazard lights switch light staying on and thought I was onto something, but left the car for about 15-20mins, came back and the light was off.
Unfortunately misplaced my size 10 spanner (doh!) to disconnect the battery and measure the quiescent current with meter and start pulling the fuses out so while awaiting a new one to come I thought I'd ask here for maybe some tips or someone had this problem before?
Oh, and the only errors I get on VCDS are:
01135 - Interior Monitoring Sensors
004 - No Signal/Communication
00323 - Vehicle Inclination Sensor (G384)
004 - No Signal/Communication
01134 - Alarm Horn (H12)
004 - No Signal/Communication
17947 - Clutch Pedal Switch (F36)
P1539 - 008 - Implausible Signal - Intermittent
I know the first three are alarm-related and I'll replace the siren with integrated battery once I find some working on but don't think that is causing the battery drain.
What do you think?
