What this guide covers
E46, E90, F30, and G20 each change diesel and petrol families. A 320d can be M47, N47, or B47 depending on year.
This guide points you at the family pages; the listing is still the unit you receive.
Fitment
E90 LCI N57 330d is not an early E90 M57. F30 320d N47 vs B47 is a common mix-up.
G20 B48/B58 petrol cars need modular codes, not N20/N55 donors, without a conversion.
What the workshop checks
Match the gearbox (manual vs automatic) and the sump for the chassis.
How to choose a listing
Use the code on the service book or VIN reply, then open that family in the shop.
