Seeing how you already have the 2009 engine, you should know that the CBEA has problematic balance shafts in the bottom end, the CJAA does not. For reasons unknown to the rest of us, Audi continued to use the CBEA in the A3 through 2014, but used all the newer bits from the CJAA engine (pressure sensors, thermostat housing, etc.) as well as a few Audi-only bits (fuel filter).

It is also technically not "legal" to install an engine from an OLDER vehicle into a newer car, although nobody will ever in a million years know you did this, and there is technically no difference so long as you install all the 2011 stuff on the 2009 long block anyway.

But seriously, you'd be better off finding a CJAA engine. Which should be MUCH easier, since there were LOTS more of those sold than the CBEA.
I hear you. But, I do already have this cbea engine. What I don't understand is why two engines that are cbea have a different casting...

If I do use this engine is there any solution that is cleaner than adding a tee to an adjacent coolant hose?

Do they make a block off plug for the hole in the block so I can use the cjaa style housing? Is there an easy way to do that otherwise?
