Car has a mind of it's own

Hi,

I'm still trying to work out all the gizmos on my A3, and I swear this thing has a mind of it's own :)

There are two things I've noticed, and wondered if anyone had any input on.

1. Automatic lights

The car has a light sensor system, which can switch the headlights on and off automatically depending on the prevailing light conditions. When I first tried this when I first got the car, it decided to put the lights on in broad daylight. Only strong sunlight would cause it to leave the lights off. This perplexed me somewhat. Obviously the car has to "play it safe", as it's far better to have lights on when you don't need them, than off when you do, but it seemed a bit overzealous.

I've now started using them again, and the system is far better, only switching the lights on when it's actually necessary.

What I'm wondering is what's changed? Has the system taken note of the ambient light levels when I've manually switched the lights on and off, and altered it's behaviour according? If so, I'm bloody impressed!

1. Wipers

Simpler one this. If I leave the wipers on (in any mode) when I leave the car, then when I return, they don't operate at all until I move the stalk to another setting. Is this behaviour by design?

Thanks for any opinions.
