What you have to remember is that many are making comparisons on how VW can have diesels such as the Jetta and think BMW can do the same.
For one thing in the US it is very difficult for BMW to offer a 3er in terms of how VW position the TDi Jetta. No matter what VW will have you believe the Jetta is not a premium car, neither is VW a premium brand.

For example the US BMW Customer would not accept the standard specification of a typical BMW 320d in all it's basic glory - cloth seats , minimal equipment - that is not the US perception of a BMW and for people to say that "BMW Should do that!" and many have including journalists, it is just not feasible.

A four cylinder diesel will come to the US Market but will be in the X1 SAV.
The next Diesel introduction will be the X3 , but do not hope for 535d and 335d as the lukewarm reaction to the 335d shows that BMW diesel in the US market works for SAV's , less so for core sedans.

In europe , the Geneva show in March will see the 330d and 335d added to the range along with xDrive.
