Overview
Community orientation
A late-2010s executive saloon offered with the modular B48/B58 petrols, the B47/B57 diesels, and the N63 V8 in the M550i. Diesel note: the BMW EGR-cooler fire campaign (T0283855EN) covered diesel production only through Sept 2016 — G30's predecessors, NOT the 2017+ G30 itself — so treat that campaign as out of scope here. This is an editorial summary, not a reliability rating; per-configuration facts and their evidence are below.
