Dead battery how to open hood?
#6
i think by now, most long term owners have re-routed the cable so it lays just under the right headlamp enclosure.
once you do this, a needlenose plier is all that's needed to manually open the frunk if and when you have no battery or the pneumatic "release" mechanism has failed.

As an FYI we make a battery that would make it so you would never have this issue again. WE also make a Harness that allows you to route it to the edge of the hood and use one of the Lithium Mini Jump Starters like our MICRO-START product to energize the car instead of going to the fuse box.... and we are having a Labor day sales....

Have done this a few times on my 04tt, actually did this this morning as the wife left the trunk unlocked for 2 days.
The release as you probably know is electric on the later ones and the battery to open it is, of course, in the trunk you can't open with your dead battery. There is a post on the fuse box you pull out to connect a jumper cable to to open the hood. Problem is when my car is in the garage my other car's jumper cable won't reach and you can't open the trunk just using a battery charger on the terminal, it doesn't work.
I didn't have a 12v battery pack available so I used a regular 9v radio battery and a 18awg 6" jumper wire with alligator clips on the ends. I clip the jumper to the fuse box post and the other end of the jumper to the positive side of the battery. I then just look for a place to touch the negative terminal to ground and flip the trunk switch.
I just keep the short piece of wire and the 9v battery in my glovebox, that way I can always get to it and always open the trunk. Any other type battery with 9-12vdc and a piece of wire will work in a pinch.

What kind of idiot designs an electric hood release when the battery is under the hood?

A 9v battery would not do it at all..... I tried.. you need a solid voltage in the 12s with the current to back it up since the cars system will automatically be pulling some juice let alone the switch which was taking from 5 to 8 amps to trigger when I did my tests. The small 9v battery would not pull that off...

Removing any of the wheels may be a problem if the wheel lock socket is stored away in the frunk.. Better to relocate the release cable to an accessible spot prior.
