Crash Test Information:
As an older vehicle, formal crash test data may be limited by modern standards. E28 chassis generally considered robust for its era.
Braking System:
Hydraulic front disc, rear drum brakes (standard); Anti-lock Braking System (ABS) often optional or standard on later/higher trims.
Seatbelts:
Standard 3-point front seatbelts, 2-point rear seatbelts (later models may have 3-point rear).
Body Construction:
Unitized body-chassis construction with crumple zones.
Audio System:
Factory-installed radio/cassette player, often with upgraded speaker options. Features are basic by modern standards.
ABS:
Anti-lock Braking System (ABS) was an optional feature, not standard on all E28 models.
Connectivity Features:
None by modern standards. Connectivity was limited to audio inputs and power outlets.
Oil Change Interval:
Typically every 7,500-15,000 km (4,500-9,000 miles) or annually, depending on driving conditions and oil used. Manual will specify for the era.
Spark Plug Replacement:
Check manual for specific intervals, often around 30,000-50,000 km (18,000-30,000 miles).
Timing Belt Chain:
M10 engines use a timing chain, which is generally maintenance-free for the life of the engine, though tensioner and guides may need periodic inspection.
Engine Oil Type Approximate:
API SF or SG, SAE 15W-40, 10W-40, or 5W-30 depending on climate. Manual will provide exact BMW specifications.
Coolant Type:
Ethylene glycol-based antifreeze mixed with water (50/50). BMW recommends specific coolant types, consult manual.
Transmission Fluid Manual:
GL-4 or GL-5 gear oil, viscosity dependent on temperature. Check manual for specific weight (e.g., 75W-90, 80W-90).
Transmission Fluid Automatic:
Dexron-III or equivalent for ZF 3HP22. Check manual for exact specifications and change intervals.
Rust Corrosion:
Prone to rust, particularly around wheel arches, rocker panels, door bottoms, and rear window seal.
Cooling System:
Radiator, water pump, and hoses can degrade over time. Heater control valve issues are common.
Electrical Gremlins:
Older wiring harnesses can become brittle, and various electrical components (e.g., door locks, windows, gauges) can develop faults.
Suspension Wear:
Bushings, ball joints, and tie rods can wear out, leading to clunks and imprecise steering.
Engine Mounts:
Engine and transmission mounts can degrade, leading to vibration and excessive engine movement.
Bmw Philosophy:
BMW's 'Ultimate Driving Machine' ethos, focused on performance, handling, and driver engagement.
