Performance Data:
Will include specifications for horsepower, torque, and engine tuning procedures for various E30 engine variants (specific figures depend on the engine covered).
Fuel System Coverage:
Details on fuel injection systems (Bosch L-Jetronic, Motronic), carburetors (on earlier models), fuel pumps, injectors, and related components.
Engine Management Coverage:
Information on ignition systems, engine control units (ECUs), sensors, and diagnostic procedures.
Lubrication System Coverage:
Detailed procedures for oil changes, filter replacement, oil pressure testing, and lubrication system component inspection.
Standard Transmission Type:
Typically 4-speed or 5-speed manual transmissions (Getrag 245, Getrag 260)
Optional Transmission Type:
3-speed or 4-speed automatic transmissions (ZF 4HP22)
Transmission Coverage:
Repair, overhaul, and adjustment procedures for both manual and automatic transmissions, including clutch service, linkage adjustment, and fluid specifications.
Exterior Dimensions:
Specific exterior dimensions (length, width, height, wheelbase) vary by E30 body style (sedan, coupe, convertible, touring) and are likely detailed within the manual, though not explicitly listed in the product description.
Curb Weight:
Curb weight varies by model and options, typically ranging from approximately 2,400 to 2,900 lbs (1090 to 1315 kg).
Gross Vehicle Weight Rating:
GVWR figures would be detailed for each specific model variant within the manual.
Crash Test Results:
While not explicitly stated, the manual will detail safety-related systems such as brakes, steering, and suspension, which contribute to overall vehicle safety. Specific NHTSA/Euro NCAP ratings for the E30 era are historical and would be researched separately.
Active Safety Features:
Information on the hydraulic brake system, including ABS (on some models) and brake adjustments.
Passive Safety Features:
Details on seat belt mechanisms, structural integrity related to chassis repair, and potentially information on earlier airbag systems (though less common in early E30s).
Infotainment System:
Primarily basic analog and digital displays for instrumentation. Radio units would typically be aftermarket or period-specific BMW cassette/radio units. The manual would cover speaker wiring and basic head unit installation/removal.
Driver Assistance Features:
ABS was an option on many models, and the manual will cover its operation and troubleshooting. No advanced driver-assistance systems (ADAS) like adaptive cruise control or lane keeping assist are present on E30 models.
Connectivity Features:
No modern connectivity features like Bluetooth or USB. Communication is limited to basic wiring for radio and accessories.
Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or annually, depending on driving conditions and oil type. Manual will specify.
Coolant Flush Interval:
Often recommended every 2-3 years or 30,000 miles (48,000 km). Manual will provide exact interval.
Timing Belt Replacement:
For M40 engines, timing belt replacement is critical, typically every 40,000-50,000 miles (64,000-80,000 km) or 4-5 years. M10 and M20 engines use chains, which are generally longer-lasting but require inspection.
Engine Oil Type:
Varies by engine and climate. Common specifications include 10W-40, 15W-40, or 20W-50. Manual will specify BMW approvals (e.g., BMW Longlife-98 or earlier standards).
Coolant Type:
Typically a 50/50 mix of antifreeze (ethylene glycol based) and distilled water. BMW historically used specific coolant types, likely detailed in the manual.
Transmission Fluid Manual:
Gear oil specifications for manual transmissions will be listed, often GL-4 or GL-5 rated 75W-90 or 80W-90.
Transmission Fluid Automatic:
Automatic transmission fluid (ATF) type, typically Dexron II or equivalent for ZF transmissions of that era.

Common E30 Issues:
Rust (especially around wheel wells, rocker panels, and sunroof), cooling system component failure (radiator, hoses, water pump), fuel pump/injector issues, differential bushings, rear trailing arm bushings, window regulator failure, fuel sender unit issues.
Bmw Heritage:
The E30 represents a pivotal generation for BMW, solidifying its reputation for sporty driving dynamics and build quality. It successfully bridged the gap between the more utilitarian earlier models and the increasingly sophisticated later generations.
E30 Evolution:
Introduced in 1982, the E30 evolved through various body styles (2-door sedan, 4-door sedan, convertible, wagon/touring) and powertrain options, culminating in high-performance variants like the M3. The 1983-1991 range covers the majority of its production life.
Production Period:
1982-1994 (though this manual covers the 1983-1991 core period)
Manufacturing Locations:
Primarily Germany, with some assembly occurring in other BMW facilities globally.
