Need to read fault codes or check a warning lamp on your 156 without a workshop trip? Motortune turns your iPhone and an ELM327 / OBD-II adapter into a scanner for the Alfa Romeo 156 (type 932): it walks every control unit it can reach, names each fault in plain language. Free to scan; the one-time $18.99 Motortune Pro adds the write features.

Adapter

3 of 10 control units — including the engine — sit on the standard OBD pins, which any ELM327 v1.5+ adapter reaches. 4 need a make-specific pin-switching cable that Motortune doesn’t support yet. 3 predate the OBD socket and can’t be reached with an OBD adapter.
