Imagine how I feel I have Clifford remote start and its a Golf R 
How did they get round the clutch having to be pressed before the car would start?
I'm sure I read when the GTI just came out across the pond the only way to install a remote start was to basically remove the ignition barrel and have a key permanently in it hidden under the dash!! How this got round the depressed clutch though I haven't a clue.
My car is specced with dsg so no need for clutch pressing, the spare keys chip is inside the alarm in the dash to override the factory immobiliser, when you start it via remote you cant drive it until you place the other key in the ignition.
My mate had a similar set up in his Sierra Cossy (a few years ago now), brilliant for the winter.
My missus wants to have this in her Corsa, during the cold weather. It would cost more than the value of her car !
