F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
The old 2000 cmc diesel N47 used 5.2 liters of oil, but the new B47 2000 cmc only needs 5 liters. How come ?
Is or is it not a new engine from scratch ? The timing chain is compatible with old one, and it makes sense not to design a timing mechanism from scratch.
