Uhhh we know about the S55 crank hub issue so in some respects seems like a prudent move/recommendation for them but this is the first time I have heard about an "N55 crank hub issue".
I've heard about N55 charge pipe issues...
Yeah some of this is not adding up - just wish there were more early adopters or folks in Europe that could respond or review the tune for the both the N55 and S55.
So for me =
