While I can't direct you to a "report", I can tell you we just did an engine replacement in an '07 with an IMS engine failure, and I personally know of at least three more that fall into your suspect model years category; I have also talked to three dealers in my area that have seen one or more of them as well. What is not known is if the larger assembly was any better or worse than the earlier designs. And as a further reference point, the larger (and final) IMS bearing assembly appeared in M96's as early as the second half of 2005, so these newer designs are only recently getting into the IMS “sweet spot” mileage, so the ones known to exist may only be the “tip of the iceberg” as for the most part, many of the later failures were covered under warranty, so no knowledgeable individual outside of the dealer network may have had a chance to examine the engine before it went back to Germany, so the owner may not have been given all the pertinent data……… But, in any case, the larger IMS bearing definitely did not end the issue…………..
