Introduction: Understanding Your F83 M4 Convertible

The 2016 BMW M4 Convertible (F83 generation) is powered by the S55B30 engine—a 3.0L twin-turbo inline-six producing 425 horsepower. This convertible variant shares its powertrain and core maintenance requirements with the M4 Coupe but adds specific considerations related to its retractable hardtop roof mechanism.

M models follow a distinct maintenance schedule with shorter intervals than standard BMW vehicles, reflecting the high-performance nature of the S55 engine and its turbocharged architecture. This guide provides verified factory service information and conservative owner guidance based on OEM documentation and technical resources.

The BMW Condition Based Service (CBS) System

BMWs, including the 2016 M4, do not follow a traditional fixed-mileage maintenance schedule. Instead, the vehicle uses a Condition Based Service (CBS) system that monitors driving conditions and calculates service needs .

How CBS Works:

• Sensors and special algorithms take into account the driving conditions of your vehicle .
• Based on this, Condition Based Service recognizes the maintenance requirements .
• Service requirements are displayed on the Control Display.
• Information on required maintenance is continuously stored in the remote control .

Important Note: Storage 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 .

Factory Maintenance Schedule Overview

While the CBS system determines exact timing, the following intervals represent the verified factory-recommended schedule for the 2016 M4 Convertible .

Engine Oil: Viscosity, Specifications, and Change Intervals

Factory Oil Specifications

The S55 engine requires specific oil approvals for proper protection.

• Capacity: 6.5 liters with filter
• Viscosity: 0W-30 LL-01FE is required for the S55 engine
• BMW Approval: BMW Longlife-01 FE

Oil Change Guidance

The CBS system typically triggers an oil change based on driving conditions rather than a fixed mileage interval . Service intervals are calculated based on driving style, engine load, and distances traveled.

Conservative Owner Guidance: Many independent BMW specialists recommend changing synthetic motor oil every 5,000 miles for high-performance S55 engines . For street use, following the CBS warning combined with an annual change is prudent.

Spark Plug Replacement

The S55 engine uses high-performance spark plugs designed for the turbocharged application.

Factory Interval: Since its introduction, BMW has recommended a 25,000-mile replacement interval for S55 spark plugs (part #12120039634) . This is significantly shorter than standard BMW engines, reflecting the high-output nature of the engine and the need for reliable ignition under boost.

Important Note: Some non-M BMWs may have longer intervals, but the S55-specific recommendation is 25,000 miles .

Brake Fluid Replacement

Brake fluid absorbs moisture over time, reducing braking performance and potentially damaging ABS components.

Factory Interval: First brake fluid change at 3 years from the vehicle's production date, then every 2 years thereafter .

Specification: BMW M4 brake systems require DOT4 specification brake fluid .

Owner Guidance: Brake fluid contamination is a gradual process; fluid should be tested periodically using testing strips to verify moisture content.

Transmission and Differential Service

Automatic Transmission

The 2016 M4 uses a 7-speed M Double Clutch Transmission (M DCT). BMW does not specify a fixed service interval for the DCT transmission, considering it a "lifetime fill" unit under normal operating conditions.

Conservative Owner Guidance: Many independent specialists recommend DCT fluid and filter service between 50,000 and 70,000 miles for long-term reliability, particularly for vehicles used in performance driving scenarios.

Rear Axle Differential

The M4 includes an M-specific rear differential requiring fluid changes.

Factory Interval: With every third engine oil change . This typically equates to approximately 30,000–36,000 miles.

Note: Some sources indicate differential fluid is also replaced at the 1,200-mile break-in service .

Air and Cabin Filter Replacement

Engine Air Filter

Factory Interval: With every second engine oil change . This typically means approximately 20,000 miles.

Interior/Cabin Microfilter

Factory Interval: At every engine oil change .
