Wow! I agree 100% I hope someone can get their hands on a clogged heater core. When I requested mine, the service adviser told me that VW is requesting any with this issue be sent back to their lab for evaluation. they did let me look at it, and I tried to blow through it, but like I said on an earlier post, it was like blowing through a cocktail straw. in addition the heater core on these cars is tiny, compared to others I have replaced on "older" cars. Admittedly I haven't replaced one since my old Ford Bronco days, but still I was amazed at how compact this core is. Anyway, hopefully after they've "evaluated" enough of these, they'll discontinue the "return to lab" protocol and someone may be able to get their hands on one.
