How do I know which engine code applies to my car? I don't see either of these codes on my VIN...

1998 A6 2.8l 30v VIN WAUBA24B2WN036925

thanks!

 

It won't be in your VIN.

My 97 A6 2.8 Avant is an AFC but I don't know about your 98.

I suspect it is an AHA - because the motors changed around 97-98. If I have it right the sedans changed in 97 and the Avants in 98. I'll check you vin against my Bentley when I get home tonight and see what it says..

 

98 is AHA or ACK

 

pretty sure it will say on either a valve cover or there is a protruding section of a head.
and NH USA, I think your right, sedan switched bodys in 97, wagon in 98.

 

I just confirmed that you have an AHA motor.

I can't figure out how to insert a screen shot of the page but that is what Bentley says you have.

 

Thanks!

 

it's an AHA. AHA is 30V. The other is 12V

 

my 98 mod. european 2.8l 30v is a ack engine:-)
