Yeah, neither the A3's ABA 2.slo, or the A4's series of them (AEG, AVH, AZG, BEV, etc.) seem to be able to hit any magical EPA target. I have owned a bunch of them. Normal driving for me, they struggle to get 25. My last one, a 2005 NB (BEV engine) quite literally used twice the fuel my ALH Golf does. Same driving, same route, same speeds. The darn things spin nearly 4k RPM at 80 MPH!
The 2011-2015 NCS Jetta with that later version of that engine (CPBA) is geared a little taller, but not much. At least those got a 6sp Aisin slushbox option (as did some of the last NB 'verts with the 2.slo), so they don't have the hideous fuel consumption of the cars cursed with the 01M. Seriously, you would never think a Jetta could get into the teens for MPG, but around town and at higher highway speeds, a 2.slo slushbox A4 Jetta most certainly will.
But, incredible thirst for fuel aside, they are a sturdy and reliable engine.
