Crash Test Results:
As a vehicle from the early 90s, official government crash test ratings (like NHTSA or IIHS) in their modern form were not as prevalent or standardized. However, the E32 was built with a robust safety cage and advanced passive safety features for its time.
ABS:
Standard Anti-lock Braking System (ABS)
Traction Control:
Available ASC (Automatic Stability Control) on some models.
Airbags:
Driver's airbag (standard on most 1991 models), optional passenger airbag.
Seatbelts:
Three-point inertia-reel seatbelts with pretensioners (front).
Body Structure:
Reinforced safety cage, crumple zones.
Oil Change Interval:
Typically every 7,500 - 10,000 miles (12,000 - 16,000 km) or annually, depending on driving conditions and oil used. Consult manual for specific recommendations.
Spark Plug Replacement:
Approximately every 30,000 - 60,000 miles, depending on plug type (e.g., copper vs. platinum). V8 engines may have a different schedule.
Engine Oil Type:
BMW recommends synthetic oil, typically SAE 5W-30 or 5W-40, meeting specific BMW LL (Longlife) specifications. Consult manual for exact specification for the specific engine.
Coolant Type:
BMW Blue antifreeze (ethylene glycol-based) mixed 50/50 with distilled water.
Transmission Fluid Manual:
GL-4 Gear Oil (e.g., Red Line MT-90)
Transmission Fluid Automatic:
ZF Lifeguardfluid5 (or equivalent Dexron III/Mercon initially, though later ZF fluid is preferred for longevity).
Common Issues:
Cooling system leaks (hoses, water pump, expansion tank), VANOS issues (on later M60 engines, though less common in early E32), ABS sensor failures, window regulator failures, headliner sagging, door seal degradation, fuel pump issues, idle control valve problems, distributor cap and rotor wear (M30). Ignition coil failures (M60).
