Even if we assume most of the 2011 failures had the older bearings, it still doesn't explain the 2009/10 trough as those productions also had older bearings.
It would be interesting to see sales volume by year. For example, the entire economy melted down in Q4 2008 and car sales in the US, in 2009, fell off a cliff, especially expensive car sales. 2010 was not much better. Maybe in 2009 BMW only sold a fraction of the cars they sold in 2008 and 2011.

Does anyone know if this data is available?
