You used to get headlight washers with the led headlights whatever model you had, although I don't think you do any more
I've not got the winter pack, but my washers are heated
Its easy to check, the washer tube leading up to the bonnet has a grey/blackish protective material cover round it, if you feel it with your fingers, if you have heated washers you can feel the power cable running up along inside with the washer tube
Do you have an early build car with the headlamp washers? I have headlamp washers but no winter pack and I'm sure I noticed a little bit of steam when I used the washer on the windscreen yesterday morning when it ws nice and cold.
