[tylerdurden]

3w sat in drive untouched.

battery was at 80% now 70%
Cannot open the car. Fob not doing a thing. Lights on fob are bright so the fob battery is fine.
Do I have a dead car.

The problem is with your 12v battery. https://www.taycanforum.com/forum/threads/locked-out-another-12v-saga.11442/

was thinking that but the car is charged to 71% and everything I read suggests the 12V is charged from the HV.

Was wondering if there is any other possible diagnosis.

The car is only a few months old. There seems no reason for the 12V battery to fail unless there was an issue

My mercedes sends me warning messages over the app when the 12V is low

Does this mean my car needs recovery?

Thanks all. Super helpful info.

given this is a near new car the correct management is to call P

Just to feedback, Porsche Assistance attended. Exactly as predicted 12V was dead.

Mechanical key to open door
Current through footwell circuit to pop front hood
Boost jump start 12V

Took him 10min.

The only explanation was I had subscribed to innodrive and cancelled the sub. The over air update was not competing and must have been attempting repeatedly when the car was off. I didnt drive it for 3w hence dead.

One thing I'm not clear on is if a CTEK trickle charger would be the same job albeit slower

Not sure that was it. I also subscribed to Innodrive as FOD and it will sent a notification that it will start installation and I think you have to approve.

I do t think it was the subscribing that did it. It was the unsubscribing and the resultant process Porsche use to delete it
