Default a close examination of etka is in order

i'm not aware of anyone having done what you require. much better for you to spend the time going through etka line by line with the relevant part numbers to ascertain differences.

You would need to swap the inlet manifold as the AVP has a single changeover stage whereas the AQF has two stages. It would run, but probably not well as the AVP has quite a lot of differences.

If you can't find an AVP, an AQH (99-01 S8) or AQG (C5 S6) will work instead.
