If there is a LTFT problem for the 3.2L engines+Stelan's AOS, it will set a MIL code of 017x
Depending on which specific code is set(rich/lean) would help decide what mods to make for the 3.2L The specifics of short/long term fuel trim would obviously be relevant
Good luck finding the tweak necessary to make this work for the 3.2L M96
* For the 3.2L M96,
just use the Audi part # 06E103245E -which is the PCV used on the Audi 3.2L engine?It blows the budget but the diaphragm is replaceable!
