A few suggestions on boot speed. 1/ Unlock your car as early as you can to wake up the systems 2/ If you have sat nav, try starting the car with the display on the radio or CD rather than sat nag, this may stop the computer trying to load maps, get a fix on location etc and improve performance for other ancillary devices such as heated devices. 3/ Try taking the car to the VW dealer as 2-3 minutes does seem excessive and the heated devices are only really useful at the very start of a journey.
