Nope the M57N wouldnt be effected as its a completely different engine design. The M57 is essentially the same as that fitted right back to the E46 330d but with revised inlet/swirl flaps etc. It has a front mounted timing chain, whereas the N57 has rear mounted timing chains (inbetween engine and gearbox).

I guess the idea of this is that the timing chain should last the life-time of the engine so being in this location shouldnt be an issue... however as i found out should you need to do any work on the chains, its an engine and gearbox out job!

Note front location of the timing chain on the m57 and differences in engine cover.
