What kind of details? Details on this family of engines? Details on common rail fuel injection? History of TDI? Or just the history of the 2.0L CBEA engine?
The CBEA is a development of an earlier Euro only common rail engine. The CBEA was all new to North America and I'm pretty sure worldwide for 2009. The current engine is the CJAA. There are a few small differences but from what I can see, nothing functional.
