Dead Battery
My 997.1 TT is dead in the garage. Any idea what could have caused my battery to drain? I did leave the keys in the ignition, but off position. Nothing works, can't even open the hood. Is there a way to get to the battery?

I could have sworn that I read leaving the key in the ignition will kill the battery. I leave mine in the ignition, but I pull it half way out. Never been an issue for me.
As for your other question, there is a page in the owners manual that tell you how to hook up a charger to the fuse panel by the drivers left foot. That provides power to the car so that you can pop the trunk.

I've tried jumping my hood from the fuse and no luck. Any reason why this isn't working?
I've heard about a cable release behind the front wheel, but the wheel needs to come off to access it.

These cars will drain the battery even with the key out after several weeks. If you a 997.1 and original battery, it's probably shot. You might as well go buy a replacement (easy enough to install once you get the trunk open).
I've had to open the trunk more than once by jumping it (which I have usually done with a battery charger, although you could use jumper cables with your new battery), never a problem. Are you sure you've got a good ground? Not having the ground cable securely attached to the chassis somewhere could be the reason you are having trouble. Also when you say jumping from the fuse, do you mean the (orange - I think) gizmo that you pull out in the fuse box to access the copper contacts on it?

Ok, finally success.
Interesting, went back and checked for a secure ground and it worked. However, It didn't pop until the key was removed from the ignition.
After getting a secure connection at the fuse box and good ground, I tried opening the hood several times and no luck. Then a clicking sound at the ignition caused me to check the key and it came free. Then pop goes the hood (or boot or whatever we call it here in USA).
Ok, rookie mistake on my part for leaving the key in the ignition.
Really appreciate the help!

Your battery will need a serious charge to get it back up to the 95-98% full state of charge (SOC).
You really should put it on a charger for a good long time. Driving the car around unless it is for extended hours will not do the trick...

So if I surmise correctly, the trunk release pull up mini lever on door sill, with the same lever type for the engine lid, is an electro-mechanical rather than pure mechanical?

If the vehicle is not started or unlocked with the remote control within 7 days, the remote control standby function is switched off (to save the vehicle battery).
1. In this case, unlock the driver’s door with the key at the door lock.
Leave the door closed in order to prevent the alarm system from being triggered.
2. Press button 1 on the remote control. The remote control is now activated again.

I left a charger on the battery all night and still not enough to turn over. Lights up and all, but very weak. I'll keep the charger on it while at work and see if that does it.
I'm thinking new battery.

It's toast - just get a new battery. If charging all night didn't fix, charging for the rest of the day won't do anything.
