I'm trying to get a replacement motor, but are these two types interchangable. The car is a 98 a4 2.8 quatro with manual transmission?
thanks

 

the AFC is a 12v engine. I'm not sure if the AHA is also a 12v but I would look in your manual or it is probably on your car somewhere, what engine you need.

 

I need the aha I THINK

 

ok so I have searched and have not found very much valuable info. I need a replacement motor for my car but don't know for sure which one. the motor was removed prior to me purchasing it. there is a place by my house that has the afc, but they don't have the aha. If someone could tell me the difference, or if they are interchangeable I would greatly appreciate it,
Thanks

 

It's to my understanding that in 98 they swithced from the 2.8L 12v to the 2.8L 30v. So '98 and up should be 30v but then again I think it calls for 3 different types. Best bet is just call an Audi Dealership and give them your VIN # and they can tell you which engine code is yours.

 

my previous 1998 2.8 30V was an AHA

 

96 and 97 were AFC - 98 on were AHA

 

you need the AHA code, the 12v v6 AFC was abandoned at te end of 97 as of 98 on the new 30v AHA took over until 2001 on the A4 and was then repplaced by the 3.0

 

Thanks, got all the info I need. Now just have to tackle the instal
