Let us know if further diagnosis shows rod bearing issues. Not so many main bearing failures have been reported.

Yes it was a rod bearing.
And yes it was frighting. Occurred on a wet single lane road in poor weather. I was lucky to avoid an accident when vehicles following me were caught unawares by my unexpected deceleration. The was little opportunity to pull over to the side of the road with safety due to the conditions. Lost power steering and power brakes which made the car more difficult to control. |

Can you help the community and take 5 minutes to file a complaint with NHTSA since it happened while you were driving? https://www-odi.nhtsa.dot.gov/VehicleComplaint/ Cheers |

So I have been trying to read up on this issue in order to do preventative maintenance on my 08 e92. It seems that in 2013 the best option was to go with treated bearings due to the clearance being equal to OEM.
Is there now a coated option that has similar clearance or better than OEM? Is this considered preferred to WPC treated bearings? I plan on using a blackstone report to determine when I really need to do it, but I am seeing in some threads (without sources) that oil analysis does not always show the issue?

Unfortunately, no one can say that only tracked cars fail. And one guy who is rabidly against bearing changes tracks his car and has experienced no issues. And other people who have never tracked their cars have had bearing failures.

So what is the chance of them failing up to now? 2%? |

"Newer factory bearings (2010.5 and later) are made from tin-aluminum, not lead-copper. Tin-aluminum bearings are 4-times harder on the surface than lead-copper bearings. This extra hardness shows signs of doing more damage to motors as there seems to be more bearing failures with 2010.5 and later vehicles. Tin-aluminum bearings also don't show the same signs of premature wear in Blackstone oil analysis due to lack of lead and copper."

If 100% of the time the wear will show a few oil changes away from failure I will wait to replace mine.

What did the dealer say? BMW NA? I assume you did the 1200 mi break in service, so the oil had ~2000 mi on it.... DCT or MT? Any serious revs prior? Were there any strange sounds or telltale symptoms or just abrupt?
