Doh?!!!! I call that part of the CBTSB, similar to the UFO debacle, tho this
one has no such CBTSB documentation attached to it. Customer bitches loud
enough, new gear and distributor goes in. Many times, I've seen old invoices
where it went in AND customer charged. No question (in my opinion) that audi
was aware of this problem. I think the 11mm tip was to design in gear wear
tolerance. It's single application design tends to reinforce that claim.
In terms of "how it would 'otherwise' manifest itself?" By a rod exiting the
block in a prejudicial method. I think these plastic gear electrically
arched pretty early in their service life, but that a bit of arching really didn't
tax the really strong rods in a stock motor. Add some software HP into the
equation, like popcorn...
Every single 20vt 3B I service, has that plastic gear inspection done unless
documented so already. I think that was the stupidest idea someone at audi
had to reinvent the toothbrush.
