Is it possible to programme the doors to lock once the car starts moving.

It is a feature my wife really likes with the children in the car and misses it from our old car.

I almost bought an ST170 and that can be programmed with a series of key turns and button pushes.

Does the octavia have a procedure to activate the feature??

Yes , a dealer can enable this , or someone with a suitable laptop and cable can use the VAG_COM software to do it for you.

There's usually someone with the tools at most of the briskoda meets who'll sort you out if you buy them a beer.

Yes. I just got into the habit of pressing the door-lock button when I get into the car.
