We _know_ this can be done.  (Queue Mission to the Moon music)

Stock VW (Bosch) parts come with timing relays and such.

Design requirements would need to include;

- OEM components as much as possible. Adds reliability, low to no cost,
and reliability.

- Stealth 'nail' to pull from socket. Location would perhaps be under
dash or driver's door or door sill. Remove as you exit to activate timer
circuit. Should be some surface that you would normally contact to pull
yourself from vehicle. Yank it and drop it on the ground as you walk
away.

- Disconnect of fuel pump I'd think. This could be done by interrupting
the coil trigger or the pump current directly. Study of schematic would
harden system to prevent jumpering relay as a solution. (Dastardly thief
may know VWs) [Dark side of the Force]

- Switch located in engine bay would serve to deactivate circuit.
Encased in weather proof enclosure, it would server to restore stock
operation; valet mode for times when it's in the shop, and if the device
malfunctions you can defeat it to get home. Last thing we want is a
Frankenstien monster turning on us.

Time to deactivate would be based on active engine running time, not
just a count down.


This may be more than the general list wants to get into, I invite
interested parties to contact me directly to kick this thing around.
