Window heaters timer

Windscreen and rear heaters I feel should be on a 15 minute timer so as to save burning the elements out. Probably the same for the mirrors as well.

Has anybody knocked up a timer circuit with say 555 or arduino?
 
What makes you think they are not timed? All my previous VWs have had these elements including mirror heaters timed?
 
The front screen light stays on for 10 mins at least. The mirror heaters don't have any visual illumination to say they are on, just the switch in the heat position.
 
Using VCDS you can reprogram the mirrors to only demist when the rear screen demist is on as well. That way, even if you leave the mirror switch on the heating symbol, it'll not overcook the element in them.
 
Mirror heaters seem dependent on model, euro 5 seems to be timed and once on will only turn off by itself but euro 6 seems to stay on and turn off when you twist the knob back but i stand to be corrected as only had an E6 as a courtesy so didnt test it out thoroughly
 
I leave mine in heat position all the time. Except when I fold them in :mad:
 
I think a little electronics module could be created and spliced into each circuit to save the elements.
