First off thanks to all the members of the forum - saved me a tow. Spent 2 hours trying to jump start my car due to dead battery and read a few posts before coming to a solution. I figured I would consolidate the information as I have to read quite a few posts to look for the solution - the information is a bit scattered. I hope this will help out anyone in need. Mods please feel free to delete or move as necessary.

For reference I have a 997.1 Turbo (2007) but this should apply to all 997s with dead batteries that cannot get the hood open for a jump start and is suffering from a dead battery.

1. Use the positive terminal / charge port in the fuse panel This is located in the fuse box by the clutch pedal (Driver's side floor). Remove the panel. There is a red terminal. PULL don't push and this terminal will come out. You will see copper contacts on this terminal. Connect positive jumper cable to the red and the ground to either the door latch or the door hinge. NOTE: This did NOT work for me, I think it does not work when your battery is completely flat. NOTE 2: Per recommendations below try the HOOD RELEASE ON THE KEY FOB!

2. Push power through your Cigarette lighter port Use a trickle charger or some type of charger to push power through the cigarette lighter. I ghetto rigged this by cutting a power inverter cable and connecting my emergency battery pack to the respective wires. This worked like a charm for me, the lights and ACC immediately turn on. Be sure to turn your headlights, stereo, etc. off first as I think the cig lighter only has a 15A fuse, you blow that and you're only option is #3!

3. Emergency Hood Latch Release Supposedly there is a hood latch release cable in LHD fender well over the driver's side headlight. You access this by removing the wheel, removing the fender lines (torx screws) and pulling on this hood latch. Anyone with experience please comment as I never found this hood latch release wire.

Hope this helps, just trying to pass it forward 6speedonline just saved me $300 tow to the dealer.

 

Great post. I've had the same issue on point 1; dead battery seemed to kill emergency release. I kept trying and eventually got it open.

I now keep a CTEK in my car at all times

 

The trick to #1 is that you have to use your key fob to pop trunk. If really flat is won't pop from inside even with jump. So after you connect battery, just use the key fob and it should pop right up.. Learned this trick at the track.

 

Winnilaker is exactly right. I was unable to pop it from inside but the key fob popped it quickly, then I was able to hook up directly to the battery.

 

Thanks for this thread. I haven't needed it yet thankfully, but it's good info to know.

 

There's also a hood release in the passenger door frame by the hinges, a small pull cable.

 

That one opens your gas cap cover not the hood. The hood release cable is buried behind the wheel well and I think it might be on the driver's side. Anyway try the pull cable you identified and you'll see what it opens.

 

Thanks guys - I didn't think to try the key fob hood release. (DOH!) I've added that to #1.

 

I used option #3 last winter after exhausting both 1&2. In retrospect, I realize that I probably did not use the keyfob but instead the button inside the car. I feel like an idiot but good experience nonetheless.

Great post. I just had to go through this last weekend. I was able to use the hood release button on the inside of the car without a problem. Good advice to use the key fob if you are having an issue though.

 

I am having surgery and will be incapacitated for two months and I just bought the Porsche Charge-O-Mat Battery Charger so I don't have to go through the dead battery problem.
