The BMW 320 / 320i, produced from 1975 to 1983 under the E21 chassis code, represents BMW's entry into the compact executive and sports sedan market. Known for its rear-wheel drive, sporting dynamics, refined engineering, and German build quality, this model offered a practical yet luxurious interior and was a direct competitor to vehicles like the Mercedes-Benz W123 and Audi 80/Fox. Powered by the M10 1.8-liter engine, featuring either Bosch L-Jetronic fuel injection or carburetors depending on the variant, the 320 / 320i delivered a driving experience focused on mechanical feedback and driver engagement, establishing a benchmark for its segment.
This comprehensive Workshop Service Manual / Repair Manual covers the BMW 320 / 320i models from 1975 through 1984. It offers detailed, bumper-to-bumper repair procedures, explanations, and diagrams for all major systems, including engine mechanicals, fuel injection, transmissions (manual and automatic), drivetrain, suspension, steering, braking, fuel, cooling, ignition, and electrical systems.
