1st off it needs to be acknowledged that the _ONLY_ thing I am doing here is publishing other people's research - too many to name - but I believe we all would agree most of the credit goes to @louv who's early diagnostics and instructions are the guide we are all benefiting from.
a big internet thank you for @louv
Question: Why is @daveo4EV posting other people's work and attempting to steal credit?
Answer: because this has gone on long enough and the information is diffuse enough and spread across other threads that a summary and single place to go I believe is warranted. If you disagree please let the moderators know and ask them to take down the post and deduct 10 points from house @daveo4EV
last request: let's keep this thread on topic - there are plenty of threads to discuss the 12 volt issue in general, Porsche's response, why does it happen, what can I do to avoid it - I would humbly request this thread remain laser focused on the steps to recover the vehicle, and any related conversations please find one of the existing threads or if necessary create a new thread.
Problem: You wake up in the morning and you find your lovely Taycan which you truly enjoy is dead. You blame @daveo4EV for this, but that doesn't solve the problem that's still dead. You remember there is some way you can recover it but you don't want to search the forums to find it.
there are 2 basic approaches to this problem. I will document both of them here for your convenience.
Approach #1 - recommended:
Answer: The best way to get a major corporation to acknowledge a mistake is to make them bear the full cost of the problem. Customers that are "fixing" the problem behind Porsche's back are masking the true scale of the problem and therefore the corporation may lack the data and necessary incentive to bring the necessary resources to bear to properly resolve the issue. It's expensive for Porsche to come haul your Taycan away, if they have to do this enough times for enough customers they might consider fixing the root problem. Certainly us "hiding" the problem from them won't help Porsche find and fix the problem, and we will be left with a great vehicle and a major defect.
this is a defect with the Taycan in either design or software or most likely both. This is not a one time thing, and it’s not trival - it’s not like we’re replacing a fuse that has gone bad and this is happening because of normal wear and tear or age of components. This is a “fault” and it shouldn’t be there. Porsche needs to know about this defect otherwise it will never get fixed. There is a clear fault somewhere in Porsche’s design, they need vehicles presented to them in this condition so they can diagnose and not only fix the problem to restore your vehicle’s functionality but also find root cause and change the Taycan so that this issue stops happening.
Approach #2 - hands on approach - I don't have time for this sh*t in my life - how do I get my Taycan back working?

please review those thread for photos and equipment recommendations.
and again I implore people to keep this thread purely 100% focused on feedback regarding recovery steps - ANY conversation/comment about the 12V issue in general or questions about why it happens, or has porsche fixed it - please redirect those good thought to an existing thread. I encourage corrections to this process or updates, but would really really like to see this thread remained laser focused on the steps to recover the vehicle and nothing else.
I used the following equipment to recover my taycan - there are other options:

Approach #1 - recommended:
- Verify you still love your Taycan
- Find your phone
- call Porsche road side assistance
- let Porsche sort this mess out since you're not a mechanic

- Tools you will need:
- known good 12 volt power source - with "clamps"
- flash light
- possibly some copper wire with both ends exposed
- vehicle key
- 15-30 minutes in my experience
- Goal: get the frunk open so we can "
jump" the 12V batterypower the vehicle’s main computer and let the car "recover" itself -it will then charge the 12V battery - You will need to open the doors to the vehicle, preferably the driver's door
- if the vehicle is locked - you'll need to extract the "emergency" key from the back of the key fob
- Open the driver's door
- place your light source in the driver's foot well and shine it on the plastic cover next the "dead pedal"
- feel around and carefully remove the plastic mostly triangle shaped cover on the left of the dead pedal
- removing this panel will expose the "fuse" panel for the vehicle
- in the panel there is a "red" tab - carefully pull this tab out so that it extends beyond the fuse panel
- this red-tab has a graphic on it - that generally indicates the frunk "opening"
- attach the positive terminal (red clamp) of your known good 12 volt power source to this red tab you just pulled out
- attach the negative terminal (black clamp) of your known good 12 volt power source to any bare metal near by attached the car
- I used the door "latch" on the "B-pillar" since it's bare metal - my 12 volt negative cable was too short so I got about 2 feet of wire, stripped both ends to bare copper and "clamped" one end of the wire and wrapped the other end on the bare metal
- this wire is now part of my recovery “kit”.
- fiddle with the 12 volt source and try and get it to provide "power" to the vehicle - in my case I had to place the 12volt booster I was using into "overload" mode
- I hear the vehicle making some clicking noises
- I used my key-fob to open the frunk
- you are now done in the driver’s foot well - we’ll be moving on to the frunk area now
- Now that the frunk is open you can access the 12V battery jumping posts (as notes in conversation do NOT attempt direct interaction with the actual 12V battery)
- Remove the piece of black plastic covering the battery jumping post - there is a plastic trim piece below the windshield wipers, but above the frunk line
- Once this piece of black plastic trim is removed - the 12V positive/+ jumping post is "under" the windshield wipers and you should see a "red tab" plastic tab
- remove the plastic red-tab cover exposing the 12V positive/+ post for the vehicle
- attach your known good 12V positve/+/red power source clamp/cable to the positive post for the vehicle
- attach your known good 12V negative/-/black power source to the negative "post" which is bare metal sticking up near by the postive post
- it's about 1/2 way between the red-post and the passenger fender of the car
- I had to place my 12V booster into overload mode, and after about 30-60 seconds the car "came" alive!!!
- remove the 12V power source
- the car should be good now and will recovery itself. Now that the car is alive again it should charge the 12V battery and normal operations can resume.
- we’re done - your Taycan is back to functional.
- Replace the pieces of trim you removed or leave them off for your dealer if you’re taking the car to service.

I used the following equipment to recover my taycan - there are other options:
- 2 feet of 16 gauge copper wire - with two ends stripped off - to extend my negative clamp "reach" to the driver's door latch on the B-pillar.
