Default CJAA vs CKRA vs CVCA

The differences between these engines can be found with some searching.

My question is what are your opinions of positive and negatives with respect to each engine.

I'll go first.

I think solenoid injectors are better than Piezo for long term durability.

A separate pumped loop for intercooler temperature control seems like additional complexity without substantial benefit (though the '15 have a phase 1 fix, and the '12-'14 don't).

The CKRA 3 year model run vs. global continued supply is an advantage to CVCA.

I know the CJAA didn't come in a Passat. This isn't really model specific, I just didn't think it was TDI 101 stuff. (move it if you want).

If this post is lame, just don't reply.
