Crash Test Data Era:
Limited official crash test data readily available for this specific period compared to modern standards, but BMWs of this era were known for robust safety cages and crumple zones.
ABS:
Anti-lock Braking System (ABS) available as an option on some models.
Traction Control:
ASC (Automatic Stability Control) or ASC+T (with Traction Control) became available on later E34 models, but less common on early 520i.

Cruise Control:
Standard or optional on most models, contributing to comfortable highway cruising.
Early Integration:
Limited to basic phone integration (if optioned with car phone) and advanced diagnostics via OBD-I.
Oil Change Interval Recommendation:
Typically 10,000-15,000 km (6,000-9,000 miles) or annually, depending on driving conditions and oil used.
Spark Plug Replacement Interval:
Every 40,000 - 60,000 km (25,000 - 37,000 miles), depending on spark plug type (e.g., standard copper vs. platinum).
Coolant Flush Interval:
Every 2-3 years or as recommended by coolant type.
Timing Belt Or Chain:
The M20 engine uses a timing belt. Replacement typically recommended every 80,000 - 100,000 km (50,000 - 60,000 miles) or 5-7 years due to risk of catastrophic failure if it breaks.
Engine Oil Type:
API SG/SH or ACEA A2-96, SAE 5W-30, 5W-40, 10W-40, or 10W-50 depending on climate. Check manual for specific recommendations.
Engine Oil Capacity:
Approx. 4.25 liters (4.5 US quarts) with filter change.
Coolant Type:
Ethylene glycol based coolant, typically BMW's original blue coolant or equivalent. Mix 50/50 with distilled water.
Automatic Transmission Fluid Type:
Dexron II or equivalent (check specific ZF transmission requirements).
Brake Fluid Type:
DOT 3 or DOT 4 (check specific recommendations for ABS if equipped).
Cooling System:
Water pump failure, radiator leaks, thermostat housing leaks, and degraded hoses are common due to age.
Fuel System:
Fuel pump wear, clogged injectors, and failing fuel pressure regulators can occur.
Electrical:
Corrosion in wiring connectors (especially ground points), failing alternator, and ECU issues can develop over time.
Suspension And Bushings:
Worn control arm bushings, tie rod ends, and shock absorbers lead to degraded handling and ride comfort.
Engine Management M20:
Idle control valve issues, MAF sensor (Air Flow Meter) problems, and vacuum leaks can cause rough idling or poor performance.
Bmw Legacy:
Building on decades of automotive engineering and motorsport success, BMW solidified its reputation for performance and luxury.
E34 Introduction:

E34 Lifespan:
Produced from 1987 to 1996 (with the Touring body style introduced in 1991).
Manufacturing Locations:
Primarily Dingolfing, Germany, with potential assembly in other BMW plants globally.
E34 Sales Volume:
Over 1.3 million E34 sedans and Tourings were produced worldwide.
Automotive Journalism Acclaim:
The E34 5-Series consistently received praise from automotive journalists for its driving dynamics, build quality, and sophisticated design, earning it a strong reputation as a benchmark in its class.
Reliability Perception:
Generally considered a reliable vehicle when properly maintained, though age-related component wear is a factor.
