Keeping a BMW running the way its engineers intended starts with the right reference. This downloadable PDF service and repair manual covers the 1990 BMW 3 Series E30 — a compact sedan/coupe/convertible/Touring built between 1982–1994 and powered by an inline-four and inline-six engines, plus the high-revving S14 four-cylinder in the M3. This is the generation that launched the original E30 M3, still regarded as one of the great homologation specials.

What’s Included

Inside, you’ll find complete engine service procedures for an inline-four and inline-six engines, plus the high-revving S14 four-cylinder in the M3, including inspection points, rebuild specifications, and the maintenance intervals specific to this generation. Transmission and driveline sections cover the rear-wheel-drive setup used on this generation, along with fluid specifications and torque values for every major fastener. Suspension, steering, and braking chapters walk through inspection, adjustment, and full component replacement, while the electrical section includes complete wiring diagrams so you can trace a fault circuit-by-circuit instead of guessing. You’ll also find heating and air conditioning service, bodywork and interior trim removal and installation steps, and a full OBD fault code index with diagnostic trouble code (DTC) definitions for the 3 Series E30. Factory torque specifications, fluid capacities, and scheduled maintenance intervals round out the manual, so nothing is left to guesswork.
