Go to wikipedia tells you everything you need to know, also Google it.

TU means Technical Update. If you are referring to the engine oil, then best to ask your local dealer. We don't have E53 diesels in the USA.

You will have diesels in the US within this year...

Ok tried but was just curious I have the M75N engine and wanted to know apart from size how it differed if it does from the m57?

No, if you have an E53 you have an M57, not an M75.

As was suggested above, all the differences for the base M57, the Technical Update (TU), and the second Technical Update (TU2) are listed on wikipedia.

As to the oil selection, the difference could be the viscosity (ie 5-30) or the API quality. Likely reasons are the different sulphur levels in the fuel, and improvements in oil made over time. If it is the API label that differs, I would use the most recent oil as they generally supercede the earlier oils.
