1985 BMW 524td Service and Repair Manual

This factory service and repair manual for the 1985 BMW 524td covers a four-door sedan with an unusual engine for the marque: a 2.4L inline-six, single overhead camshaft, turbocharged, running on diesel. Compression ignition changes what service work looks like — injection timing, injector and pump specifications, glow plug testing and fuel system bleeding replace the ignition side of a gasoline car — and this manual carries that data along with the turbocharger and charge-air procedures for the single listed trim.

Known issues on the 1985 524td. The diesel six sets the priorities. The manual gives compression values, injection pump timing procedures, injector testing and nozzle specifications, glow plug and preheat circuit diagnostics, and the bleeding steps a diesel needs after any line has been opened. Turbocharger and exhaust torque figures sit with them. The rest of the sedan — gearbox, rear axle, brakes, suspension, steering, heating and body wiring — is documented with the specifications and diagrams that belong to each system.
