Guide says that a hood switch and valet switch are necessary, is it really?

Question

I've looked online and haven't seen anyone installing these on 08 VW's

Answer 1

Hood switch and valet are meant as security measures so that the vehicle is not accidentally remote started while someone is working on the engine! The hood switch will prevent the remote starter from engaging when the hood is open. The valet switch gives control of enabling and/or disabling the remote starter completely.
