I haven't looked into it carefully, but isn't there a pan on the bottom of the engine so "tear down" seems a little strong for what it may require to torque the bod bolts.
I tried to cajole the mechanic into going ahead and doing the repair with me paying and getting refunded when the fix comes out, but as far as my shop knows, BMW still hasn't come out with a hard fix procedure. They do not know if the existing con-rod bolts will be re-used and new hi-temp loctite applied, or if BMW will provide new con-rod bolts and loctite. They didn't want to do it, even with me paying beforehand because if what they do isn't the "official" fix, then they'll have to do it again....

Good to hear one is being repaired! Not-so-good to hear about the missing loc-tite...things may be more than the 1% initially reported. I will add my results to the thread.
My dealer has all parts for mine except for a gasket or 2; and so I probably won't see mine till next weekend.
Good job to the MOA and forum, and a "shoulda done better" to the corporate types.
The thread you responded to is a year old. OMI spoke with Anthony Cavanaugh at BMW NA and he said that the problem was caused by an anti-seizure coating being placed on the rod bolts by the bolt manufacture. This anti-seizure coating is what caused the problem.
According to BMW NA they discovered that was the anti-seizure coating on the bolts put on there by the bolt manufacture that caused the bolts to back out. The coating caused the torque value to be incorrect.
This is old news and all affected bikes have been corrected.
