NNN or MSB is the ECU Part Number

NNN****** = flashable (post 2002)

MSB****** = non reflashable (pre 2002)


The other part -
NNW***** is the assembly number.

This assembly number represents a vehicle configuration of:

1) 2.5 L diesel 5 cylinder engine (TD5);
2) Defender body type;
3) 90 inch wheelbase;
4) Manual gearbox;
5) With or without air conditioning;
6) Fuelling tune specification is for the European market.
