2021 BMW 230i Service and Repair Manual

This factory service and repair manual for the 2021 BMW 230i covers a two-door convertible and a two-door coupe, both in Base trim, both powered by the turbocharged 2.0L DOHC inline-four of 122 cubic inches. With a single engine to document, the manual spends its detail on the surrounding systems — the transmission and driveline, the chassis settings, and the body electrics that differ most between an open car and a closed one — rather than on sorting between powerplants.

Trims covered

Known issues on the 2021 230i. Two recalls are on the federal record. One covers a seat belt retractor that may not do its job in a crash, so the belt does not restrain the occupant as it should. The other covers supports inside the roof liner that may be insecurely attached; a loose support can drop into the passenger compartment, and it sits where the head air bag needs room to deploy. Restraint system procedures, belt and buckle checks and the interior trim removal steps involved are all set out here.
