No integrated Bluetooth, USB, or smartphone connectivity. Analog systems only.
Oil Change Interval:
Typically every 5,000-7,500 miles or annually, depending on driving conditions (refer to manual for exact specifications)
Spark Plug Replacement:
Varies by engine type; typically around 30,000 miles for older spark plugs, potentially longer for platinum or iridium plugs
Engine Oil Type:
Typically SAE 10W-40 or 15W-50, or 20W-50 for older/higher mileage engines. Specific BMW approval grades like BMW High Performance Synthetic Oil (or equivalent API SG/SH rated oil) are recommended. Consult manual for precise viscosity based on climate.
Coolant Type:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. BMW Blue or BMW Green coolant specifications apply.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid
Transmission Fluid Manual:
API GL-4 gear oil (e.g., SAE 75W-90 or 80W-90) is common. Specific BMW part numbers and viscosities should be cross-referenced.
Transmission Fluid Automatic:
ATF Dexron II or Dexron III specifications (refer to manual for exact type and BMW approval number).
Common E30 Problems:
Cooling system leaks (hoses, radiator, water pump), fuel injector issues (later models), fuel pump failure, trailing arm bushing failure, strut mount wear, sunroof drains clogging, rust (especially on fenders, rockers, and rear wheel arches), dashboard cracks, idle control valve issues (early injection models).
