I never had an issue with my N52 motor. It worked great up till when I sold it 2 months back with 49k on it.
As for the smell I always had a weird smell when driving in manual mode. If I drive it normal auto mode I never had a smell. I smelt that since I purchased it but never thought twice about it.

i have had a lot of disappointment from the life span of the parts in my engine and for its age they never should have broken as soon as they did
