I have nearly completed updating the excel file with engine failures that have been reported since the last (Aug 2014) update 6 months ago.
The updated numbers and graphs should hopefully be completed later today.
There have been quite a few, 13 with sufficient details (minimum M3post username, year and mileage) two I'm awaiting email replies, and 1 supercharged.
Of these, one had a double engine change where the second engine was a used one of unknown provenance which then also failed (this second failure has not been added).
So we are looking at about 2 to 3 failures a month for M3post members.
The trends appear to follow the same patterns seen in previous updates.
The stand out one again is that 2011/2/3 cars are more likely to fail than earlier cars as a function of production numbers and mileage.
Indicating that the change that occurred around the 2011 MY (July/Aug 2010) to the newer spec bearings with a larger bearing clearance significantly reduces reliability in the S65 engines.
