That should clear up (or not) the EA837 3.0T supercharged codes.The Audi A4 of 2008 marked a significant improvement in the weight distribution of the drivetrain of front wheel drive Audi models. The hp numbers in the chart are AoA's marketing numbers, ie metric hp, not real brake hp values (so 211 and 220 are really 208 and 217, but since no one would recognize the real hp values. CTVA and CTXA are listed as Q5, but what for or where, who knows. Maybe they were non-EU ROW engines? Looks like it (CTDA, S5 Korea, CTTA, A6/A7 China). I have no idea what the CTDA/CTTA/CTVA/CTXA codes represent. magnetic disengagement clutch for the supercharger, and full port and direction injection, but only on the EU engines (CREx).Ģ014-2016/2017 B8.5 S4/S5, 333hp CTUB (US D4 A8 2013-2017 also used this) Third wave - EA837 gen 4 (evo) - this was a fuel efficiency and emissions reduction effort to meet the EU 6 W standards starting in 2014. Second wave - modified for stop/start and for no more power steering pumpĢ012-2013 C7 A6, 310hp CGXB (EU version CGWB/CGWD CGWA was EU A8)Ģ013 B8.5 S4/S5, 333hp CGXC (EU version CGWC)Ģ013 B8.5 Q5, 272hp CGXD (EU version CMUA, which could also be had on the A4/A5 there) Other codes you might run across would be CHMA (China A6/A7), CHMB (China A5), CNAA (China Q7). As for the 3.0T supercharged, what I see is (from a US products perspective):Ģ009-2011 C6 A6, 300hp CCAA (EU version CAJA)Ģ010-2012 B8.0 S4 sedan / S5 cabriolet, 333hp CCBA (EU version CAKA)Ģ011-2013 4L Q7 S-line, 333hp CJWB (EU version CJTB)Ģ011-2012 4L Q7, 272hp CJWC (EU version CJTC)Ģ012-2013 4L Q7, 280hp CJWE (mixed info on if the 2012 had the 272 or 280 version) The relevant B8 2.0T engines should be well enough known at this point.

That list seems to have some issues with it. CFSA - RS5 V8 (2010–2015)I was thinking of doing a rs3 engine swap on my Audi A5 but have found no information on it or if it’s even possible. I am not planning to do a manual swap, since there is no handbrake on Audi :(īeside the engine and transmission, what else do I need? ECU, TCU.etcġ. So I hope to start this thread to help myself and anyone who wants to do a engine swap on their A4 in the future. I assumed transmission needs to be swapped if I use a S4, SQ5 S5 or RS5 engine, can someone confirm that? I already did a some research online, however information I found was bit and piece, and mostly on 8.5 swap.

I drive average 35,000km per year, hopefully I can drive it for another 2-3 years.Īnyway, I am doing research and wondering what's the available options for engine swap.

I have a 2012 A4 Avant S-Line, 8spd automatic ZF8HP55 with 169,000KM, engine is running good with oil consumption.
