Audi has changed part revision in the past and not changed the suffix and that is possible through a few loop holes. We know that Audi didn’t want to release the next updated batch of intake until 0ctober of this year.
Now consider this. They know there is issues. If I’m correct compugeek5150 if you look at your intake the intake isn’t actualy new correct. Its what looks to be an old intake that failed that got sent back to the manufacture for an update… correct.
IF what I can figgue is correct Audi has sent several of these intakes back to the manufacture and obviously they need to repair them. In that prosses the manufacture obviously would see the flaw in there prosses. And part of that is that the mechanisms get bound up and the mount comes loose. So in theory the real issue is the mount.
That being the case the manufacture can look into reinforcement of the mount and bigger tolerances in the mechanisms. Doing so would make for a better intake but not require any actual hard ware changes and thus not require any suffix changes. Audi and the manufacture would know if you have an updated intake by the actual build on date.
