No, not usually flimsy at all. But, the '06s seem to be going through some growing pains.
The replacement clusters are on national back order. The good news is that VW is shipping out the new improved ones as fast as they can have them made.
Welcome to VW! The 06 is a rather large redesign (with that Inline 5 and the new interior, essentially, it's a whole new car -- and could be a CAN-based computer, too, which means it's a whole new "generation" of car in terms of electrical diag). In 1998, when the first 2.0s rolled off the lines, they had similar issues. It's all got to do with the makers who make the individuals components, QC issues that are sadly out of VWoA/VWAG's hands. Your dealer will get you taken care of, and usually you have a minimum set of problems. I do find it odd that it's only the 06 TDI owners who have seen cluster issues (especially since TDIs are supposedly built later in the year, or so I thought).
