I have a 2013 BMW 550 with the N63 engine. There is much negative publicity on this engine. I am curious if you personally have issues with this engine and what they were. Mine is approaching 140 000 km and expect for heavy oil consumption, have no issues. Should I keep the car for another 30 to 40 k? I love the car and in general it has been great.

M550I uses n63TU gen engines which remedies most of the issues the n63 had. Having owned both the n63 is a ticking time bomb in every aspect. From timing chains, chain guides, rod bearings, valve seals the list goes on.
