Default AAH vs AFC engine code

Hi
I have a '95 90 Quattro that is needing an engine. I have verified that it is the AFC engine code. I am looking at a 2.8 out of a '97 A4, but don't know if it's compatible and even what the difference is between the two codes???

Any info would be greatly appreciated.

Thanks in advance!

You will want to read through this entire site eventually:

<b><u>12v.org</u></b>

It will give you the technical differences; &

here is a link to where one choice is "Identification"

Thanks, Lago. I've been out of the VW/Audi scene since the early 90's. Looks like I've got a lot of reading to do. Thanks again.

I believe the 97 would be obd2 which I believe would be a problem.

as long as he changes the sensors and the flywheel, he should be fine.

The A4 will have an AFC, exact same engine, if the A4 is a manual, it even uses the same transmission. Use all of your sensors and harnessing, the A4 will be OBDII, your car is likely OBDI (switch was in 1996 I believe).

The AAH is the older 2.8L engine, first used in the 1992 100, last used in the 1994 100 and 90. It MAY have snuck in to some '95 cars.
