E28 chassis generally considered robust for its era. Active Features Braking System: Hydraulic front disc, rear drum brakes (standard); Anti-lock Braking System (ABS) often optional or standard on later/higher trims. Passive Features 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. 💡 Technology Features Infotainment Audio System: Factory-installed radio/cassette player, often with upgraded speaker options. Features are basic by modern standards. Driver Assistance ABS: Anti-lock Braking System (ABS) was an optional feature, not standard on all E28 models. Connectivity Connectivity Features: None by modern standards. Connectivity was limited to audio inputs and power outlets. 🔧 Maintenance Service Intervals 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. Fluid Specifications 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. Known Issues 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. 📚 Vehicle History Brand Heritage Bmw Philosophy: BMW's 'Ultimate Driving Machine' ethos, focused on performance, handling, and driver engagement.
