F10 550i (N63 / N63tu) reliability
Hello all,
I plan to change (January 2016) my actual e60 530xd by an 550i.
I seen lot of people on forums which had problems with the N63 engine.
So I hesitate to take on now...
Any idea on this ?
And what about the reliability of the M5 with the S63 engine made after the recall (for the oil pump) ?
Thanks

I've read the N63TU engine is the updated V8 and has corrected all that is wrong with the N63. I'm not an expert by any definition, that's just what I've read......
YMMV....

I've just checked on realoem website and in fact, there is not N63Tü on the F10 
So all F10s have only the N63...

ok but maybe just in US market, because in Europe the 50i is not present on the F10 anymore since 2013 or 2014

Maybe it's a sign to get a 7 series lol
I just did a significant amount of work on a TU that swallowed a bunch of water. Locked it up, fried the starter. The customer insisted I do everything in my power to save the engine. After removing both intercoolers, sucking water out of the intakes. Replacing all 4 pressure sensors, starter, all 8 plugs, new maf sensors, air filters and changing the oil 3x. The customer has since put 1100 miles on it with no issues. To me that says something about the strength of the internals. I've never seen an n20 or n55 survive water injestion.
They did redesign a lot of the stuff from the original n63, which can only be a good thing. And it's SO MUCH easier to work on.
