2013 BMW Z4 sDrive28i Service Requirements & Maintenance Schedule

Key Takeaways

• Condition Based Service (CBS): The 2013 Z4 sDrive28i uses BMW's CBS system, which monitors driving conditions to determine when service is needed, rather than following a rigid fixed schedule. This information is displayed on the instrument cluster and stored in the remote control .
• Engine: The sDrive28i is powered by the 2.0L turbocharged N20 inline-4 engine, paired with a rear-wheel-drive configuration . This engine is the first year of production for the E89 Z4 and is known for certain long-term considerations.
• Oil Specification & Capacity: Requires BMW LongLife-01 (LL-01) or LL-17 FE+ approved synthetic oil. The recommended viscosity is 5W-30 or 5W-40 for most climates, with 0W-20 options available for specific applications . Engine oil capacity is 5.0 liters (5.3 quarts) .
• Major Service Intervals: Spark plugs at 45,000, 90,000, and 135,000 miles; oxygen sensors at 120,000 and 150,000 miles ; fuel filter at 37,000 miles (60,000 km) ; air filter at 12,000 miles (20,000 km) .
• Critical N20 Timing Chain: The N20 engine is known for potential timing chain guide and tensioner issues. Proactive inspection is recommended, with some specialist guidance suggesting replacement around 62,000 miles (100,000 km) .

Understanding BMW's Condition Based Service (CBS)

The 2013 BMW Z4 sDrive28i utilizes BMW's Condition Based Service system. Sensors and special algorithms take into account the driving conditions of your vehicle to determine maintenance requirements, making it possible to adapt the amount of maintenance to your user profile . A service interval warning is standard equipment on this model .

Service information is displayed on the instrument cluster. The vehicle continuously stores data on required maintenance in the remote control; a service center will read this data and recommend the right procedures .

Storage Periods: Stationary periods during which the vehicle battery was disconnected are not taken into account. If this occurs, have a service center update the time-dependent maintenance procedures, such as checking brake fluid and, if necessary, changing the engine oil and the microfilter/activated-charcoal filter .

Factory Scheduled Maintenance

BMW's maintenance guidelines are sensor-driven and center around a CBS system that is cycled to occur every 10,000 miles, whether it involves a simple oil change or other standard service . BMW utilizes electronic oil measurement to monitor the engine load on the current oil fill, based on driving style and distances .

Engine Oil & Filter Change

OEM Factory Recommendation: Engine oil and filter changes are determined by the CBS system, typically occurring every 10,000 miles or 12 months, whichever comes first. Oil capacity is 5.0 liters (5.3 quarts) .

Owner Guidance: Pelican Parts recommends changing synthetic motor oil every 5,000 miles for optimal engine protection . More frequent changes are strongly advised for the N20 engine due to its timing chain sensitivity; oil quality directly affects timing chain longevity.

Oil Specifications: The N20 engine requires oil meeting BMW LL-01 or LL-17 FE+ approval . Compatible viscosities include:

• 5W-30: BMW Longlife-01 approved
• 5W-40: BMW Longlife-01 approved, with 5W-40 being a common recommendation
• 0W-20: BMW Longlife-17 FE+ approved for specific applications
• 0W-30: BMW Longlife-01 FE approved

Spark Plugs

Factory Recommendation: BMW specifies spark plug replacement for the N20 engine at 45,000 miles, with subsequent replacements at 90,000 and 135,000 miles . The N20 engine uses four spark plugs (one per cylinder).

Kilometer Equivalent: Some sources also note spark plug replacement at approximately 43,000 miles (70,000 km) .

Oxygen Sensors

Factory Recommendation: The oxygen sensor must be replaced to maximize vehicle fuel economy and minimize exhaust pollution. Replacement intervals are specified at 120,000 miles, with a second replacement at 150,000 miles .

Air Filter

Factory Recommendation: Air filter replacement is recommended every 12,000 miles (20,000 km) . After prolonged driving in particularly dusty conditions, it is advisable to check the condition of the air filter earlier and replace it if visibly dirty.

Fuel Filter

Factory Recommendation: Fuel filter replacement interval for the Z4 sDrive28i is 37,000 miles (60,000 km) .

Engine Coolant

Factory Recommendation: Engine coolant (antifreeze) replacement is recommended at 120,000 km (approximately 75,000 miles) or 8 years, whichever comes first .

Brake Fluid

BMW recommends brake fluid replacement every two years from the vehicle's production date, or as indicated by the CBS system . Some sources indicate brake fluid may be changed at the 30,000-mile mark, then every 60,000 miles thereafter .

Serpentine Belt & Tensioner

Owner Guidance: The N20 engine uses a serpentine belt to drive the alternator and A/C compressor. A snapped belt from age or a seized tensioner pulley can damage components. Condition-based inspection is recommended; a proactive service around 80,000 miles is advisable.

Timing Chain, Guides & Tensioner (N20 Critical Consideration)

The N20 engine is known for potential timing chain guide and tensioner issues, particularly on early-production models . The original timing chains are prone to stretching, and the chain guides can wear out faster than expected .

Symptoms to Watch For: Cold start rattle (sounding like a muted diesel engine), high-pitch whining noise from the lower engine area near the oil pump, or unusual engine noises .

Recommended Action: There is no official replacement interval, but specialist guidance suggests inspection and proactive replacement around 62,000 miles (100,000 km) . BMW updated the timing chain components, so replacement kits with revised parts are available .

BMW Factory Coverage

The 2013 BMW Z4 sDrive28i came with BMW Ultimate Care, providing free scheduled maintenance for the first 3 years or 36,000 miles . The vehicle includes a standard 4-year/50,000-mile basic and powertrain warranty, and a 12-year/unlimited-mile corrosion perforation warranty . BMW TeleService is also included, which automatically alerts BMW when service is needed .
