Recommended Fuel:
Unleaded gasoline (Octane rating varies by engine, typically 91 RON or higher)
Transmission Options:
5-speed manual transmission (Getrag 260/5, Getrag 260/6) and 4-speed automatic transmission (ZF 4HP-22, ZF 4HP-24)
Transmission Options:
5-speed automatic transmission (ZF 5HP-18, ZF 5HP-24) on later models (e.g., 540i)
Clutch Type:
Hydraulic clutch actuation for manual transmissions
Differential:
Limited-slip differential (LSD) available as an option on certain models and performance variants
Audio System:
Factory optional sound systems often included cassette players, CD changers, and premium speaker options from brands like Blaupunkt or HiFi Systems.
Navigation:
Early navigation systems (e.g., BMW Trafficmaster) were available as rare options on later models.
Cruise Control:
Electronic cruise control was a common option.
Traction Control:
Automatic Stability Control (ASC) or Automatic Stability Control + Traction (ASC+T) was available as an option on many models.
Phone Integration:
Factory-installed car phone kits were available as an option in some markets.
Oil Change:
Typically every 10,000-15,000 miles or 12-24 months, depending on driving conditions and oil used. The manual will provide specific guidance.
Spark Plugs:
Intervals vary by engine type (e.g., iridium plugs on later M50 engines have longer life than standard copper plugs on M30).
Timing Belt Chain:
Inline-6 M30 engines use a timing chain; Inline-6 M50 engines and V8 M60 engines also use timing chains, generally designed for the life of the engine but require inspection.
Engine Oil:
API SG/SH or higher, SAE 0W-40, 5W-30, 5W-40, or 10W-40 depending on climate and specific engine. The manual will specify exact grades and BMW approvals.
Coolant:
BMW-approved ethylene glycol-based coolant (typically blue or green). Mixing with incorrect types can cause damage. Capacity approx. 7-9 liters.
Brake Fluid:
DOT 3 or DOT 4 brake fluid. Replacement every 2 years is recommended to prevent moisture absorption.
Transmission Fluid Auto:
Specific ATF fluid (e.g., Dexron III or equivalent). ZF transmissions have specific fluid requirements, critical for longevity.
Transmission Fluid Manual:
GL-4 or GL-5 gear oil depending on gearbox type. Manuals often specify specific viscosity grades.
Cooling System:
Plastic coolant expansion tanks can become brittle and crack; water pumps and thermostats can fail.
Suspension Bushings:
Wear on control arm bushings, trailing arm bushings, and subframe bushings leads to poor handling and alignment issues.
Electrical Connectors:
Corrosion or degradation of wiring harness connectors, especially in the engine bay and under the dashboard.
ABS Sensors:
ABS wheel speed sensors are prone to failure, leading to ABS warning lights.
Head Gasket M60:
Early M60 V8 engines (especially pre-facelift) had issues with oil pan gaskets and sometimes head gasket failures, though less common than other E34 issues.
Heater Core:
Heater core leaks are a common issue, often requiring dashboard removal for replacement.
Bmw Philosophy:
BMW's reputation for sporty handling, advanced engineering, and driver-focused luxury.
E34 Introduction:
Introduced in 1988 (as a 1989 model year) in Europe, succeeding the E28 5 Series. It represented a significant advancement in styling, technology, and performance.
Facelift:
Received a significant facelift (Sonderausstattung) in 1994, introducing updated styling, improved engines (e.g., M50TU), and revised interior and exterior details.
Production Period:
1988-1996
Manufacturing Location:
