UPDATE:
Good news, nothing is wrong with the car, battery is OK. The only thing they found (and i take it back, they know about the "Energy Diagnosis" procedure):
PHP Code:
Fault: Terminal 15 on too long with engine turned off
- Frequency:0
- Switched-on period (resolution of 5mn): 45
- Key or ID transmitter was in vehicle interior
- state of battery charge reached the startability limit
And that put the battery in a total discharge mode and then it disconnected itself for safety (undervoltage).
Not so good news: They wanted to charge me which I refused, and they washed my car against my wish, sigh ...
Now the mystery still remains, what "accessory" kept that terminal 15 ON for 45mn ??? I dont have anything connected physically to the car, no modifications, no mp3 usb, light switch is position OFF, nor was my key in the car, nor was I... And really, 45mns of whatever accessory (be it radio, lights, ...) can totally discharge the battery ?
I could say a comedy almost broke out with all the reasons they were giving trying to place fault with the operator (owner). The guy said maybe someone was triggering the car alarm in my closed garage constantly while I didn't hear it in my house ... seriously
???
