N62 versus N62TU engine, any idea?
 

Does anyone know the difference between these two engines? (like from a BMW tech report or something?)

with the N64TU,TU= technology update.
as the same with the TRANNY ZF...PU=part update.

Do you know what the update was and when it was implemented?

TU = technical update
2 variants of N62(successor to M62TU) Valvetronic engine; 315hp 4.4 liter version and the 355hp 4.8 liter version. N62 are mated only to 6-speed automatic tranny.
4.4 liter 4.8 liter

Anyone know when it was implemented in the production run?

TIS Bulletin that lays out the N62TU revisions
 

This TIS bulletin that lays out the N62TU revisions from the N62:

Great information in that bulletin

Seems worse IMO lol... no magnesium diva intake, no dipstick, "intelligent" alternator/battery coding, etc...

I juat brought one of this engine home yesterday. To upgrade my X5. But I will be using my engine management and the intake from my X5. I will just have to work with tuning it. Only pros is better internals and the fact thats is a 4.8l. For the SC.
