I wouldn't put an stock in this guy's review. He writes for USA Today and thinks he is an expert.
It sounds pretty ignorant and lack of experience in new diesel technology.
This diesel engine has won top 10 engines of the year award by Ward and JD Power as well as World Green car of the year along with 2009 VW Jetta TDI.

This numb nut should just stick to reviewing domestic cars like his Ford Taurus because he is just too close minded.

The iDrive is has been adopted by other car makers now because it is that innovative. Audi has.
Some ppl just don't realize how easy it is to use if spend a little time learning the system. But I guess it is the same kind of ppl that could not take the time to learn how to program their VCR.
