Guess we have to wait to find out, but is the fix just a reversion to pre-29.2 Progman software? If so, choices would be
i) Accept Wastegate rattle (and John Deere sounding engine), but get performance
ii) Eliminate WG rattle and have laggy software
unless one were to follow Mr5's diy in the FI forum, but...I see i) and ii) as being most likely for N54 owners. Hopefully, BMW came out w/ a software version that addresses Wastegate noise AND allows for the low-end grunt we fell in love with when we bought these vehicles!
