This is my first post so forgive me if this has already been posted (I've checked but can't find anything similar).
I'm after getting a 05 MK5 Astra but to my surprise there is no warning noise when I open the Drivers door and the lights are left on.
My last car used to warn me if I left them on but my new Astra doesn't.
Is it faulty electronics or is this just a "feature" with the Astra MK5???
