hello all, I purchased my parents 2010 Jetta TDI with 137,500 on the clock approximately 2 months ago. It now has almost 140,000. I'm very happy so far. Just a few concerns ...the A/C take about 5-8 minutes to actually kick on. I noticed both fans do not turn on right away also. Secondly, the rear passenger side door doesn't close flush. Upon further inspection, I observed that the metal hinge attached to the frame is loose. Does anyone know what kind of tool to use to tighten the two nuts? Other then that I'm very happy. Not getting the 44 mpg my mother was..more like 35-37 (more city driving). Thanks Guys and Gals!
