I ordered a Golf TDI...still waiting for it and have no idea when I will get it. This will be my third VW. First was a 2003 GTI VR6. Current is a 2006 GTI. The 03 was the first car I ever had with climate control, and I hated driving my wife's car because I had to constantly fidget with the fan and temperature to be comfortable, in spite of the fact that it supposedly has climate control. The VW climate system is awesome in my opinion. I can go months and months without ever adjusting anything, and always be comfortable. I always said that I would never get a VW without it again, would pay a little extra for it. Unfortunately I was unable to get the climate control on the new TDI...it simply wasn't an option. So...a couple questions. First, how is the climate system in the new Golf? If you already have a TDI, do you find yourself making a lot of adjustments? Also, is there a way to upgrade it yourself, like many people do with headlight switches and things like that? I'm assuming not. Seems like it would be more complicated than that. Thanks for your help.
