Touareg :: Heated Steering Wheel Work Intermittently?

Since the day I purchased my Touareg, the heated steering wheel has worked inconsistently (usually not at all). I bought it in November of 2003 and thoughout the winter I brought it in 5 times telling them that it would not turn on when I started the truck. Of course, having an early VIN truck I don't have the symbol that tells me the wheel is supposed to be heating, so I have to guess... But with below freezing temps, I turn the truck on, push the button and nothing happens. After 5 minutes I push the button again and still nothing happens. Every time I took the truck in, the dealer told me there were fault codes in the truck saying that the heater was stopping because of a lack of required voltage. Several electrical fixes later (some parts blew out at various times and were replaced), it seemed to work. Then Spring came and it won't turn on until fall when it gets cold again... This past fall, I reported the problem again and they put several updates and fixes into the truck but they have not been able to fix the problem.

Today, I went back into the dealership and they told me this was "normal"... The note they put in was as follows:"Tested steering wheel heater in GFF. Steering wheel heater is not failing. Customer will only be able to tell if the heated wheel is working on really cold days. Steering wheel only heats up to 77 degrees."

When it works, there's no mistaking that it's on and it does shut off when it reaches a warm temperature. But when it's 25 degrees out and it doesn't warm the wheel - it seems to me that it's broken... Have such a hard time telling when their heated wheel is working?
