Introduction: Understanding Your F83 M4 Convertible

The 2017 BMW M4 Convertible (F83 generation) is powered by the S55B30 engine—a 3.0L twin-turbo inline-six producing 425 horsepower in standard form. 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

Modern BMWs, including the 2017 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 using sensors and special algorithms.

How CBS Works:

• Service requirements are displayed on the Control Display
• Oil change intervals are calculated based on driving style, engine load, and distances traveled
• Service data is stored in the remote control key and can be read by a service partner

Factory Maintenance Schedule Overview

While the CBS system determines exact timing, the following intervals represent the verified factory-recommended schedule for the 2017 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 recommended for the S55 engine; 5W-30 LL-01 is also approved
• BMW Approval: BMW Longlife-01 FE or Longlife-01

Oil Change Guidance

The CBS system typically triggers an oil change based on driving conditions rather than a fixed mileage interval. The initial calculation often shows approximately 10,000 miles until service, but hard driving and frequent stop-and-go conditions may accelerate the interval.

Conservative Owner Guidance: Many independent BMW specialists recommend changing oil every 5,000–7,500 miles for high-performance S55 engines, especially for track use. 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. This is significantly shorter than standard BMW engines, reflecting the high-output nature of the engine and the need for reliable ignition under boost.

Part Reference: Genuine BMW replacement part #12120039634.

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.

Owner Guidance: Brake fluid contamination is a gradual process; fluid should be tested periodically using testing strips to verify moisture content. A complete brake system flush is the recommended service, not merely a fluid top-off.

Transmission and Differential Service

Automatic Transmission

The 2017 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 change is also performed 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.

BMW Ultimate Care Overview

The 2017 BMW M4 comes with BMW Ultimate Care, which covers factory-recommended scheduled maintenance for 3 years or 36,000 miles, whichever comes first. This includes:

• Engine oil and filter changes as indicated by CBS
• Brake fluid as scheduled
• Cabin filter replacement

Frequently Asked Questions

Is the 1,200-mile service required on the 2017 BMW M4 Convertible?

Yes. The 1,200-mile break-in service is mandatory for all BMW M models and is required to maintain warranty coverage. It includes engine oil and filter replacement, intercooler inspection, and differential fluid replacement.

What type of oil does the 2017 BMW M4 Convertible use?

The S55 engine uses 0W-30 LL-01FE or 5W-30 LL-01 viscosity oil meeting BMW Longlife-01 FE or Longlife-01 specification. Capacity is 6.5 liters with filter.

When should spark plugs be replaced on the 2017 M4?

BMW recommends a 25,000-mile replacement interval for S55 spark plugs. This is shorter than intervals for non-M BMW engines.

How often should brake fluid be changed on the M4?

The factory interval is 3 years for the first change, then every 2 years thereafter.

Does the 2017 BMW M4 need transmission fluid changes?

BMW does not list a DCT transmission fluid change as a standard maintenance item, considering it "lifetime fill." However, conservative owners and independent specialists recommend servicing the M DCT every 50,000–70,000 miles for long-term reliability.

How often should I change the engine oil in my M4?

The Condition Based Service system recommends oil changes based on driving conditions rather than a fixed interval. Conservative owner guidance suggests 5,000–7,500 miles for performance driving or track use.

What is the rear differential oil change interval for the M4?

The factory recommends changing the rear axle differential oil with every third engine oil change. This equates to approximately 30,000–36,000 miles. Some sources also indicate it is changed at the 1,200-mile service.

When should the engine air filter be replaced on the 2017 M4?

The air filter should be replaced with every second engine oil change, approximately every 20,000 miles.

Does the 2017 BMW M4 have a timing belt or timing chain?

The S55 engine uses a timing chain, not a belt. The chain is designed for the life of the engine and does not have a scheduled replacement interval.

What is covered under BMW Ultimate Care?

BMW Ultimate Care covers factory-recommended scheduled maintenance for 3 years or 36,000 miles. This includes engine oil changes, brake fluid, cabin filters, spark plugs, and vehicle checks based on the CBS system.

How long do brake pads typically last on the M4?

Brake pads often last 30,000 to 40,000 miles, though this varies significantly with driving style. Highway driving and smooth braking can extend lifespan, while track use and aggressive driving shorten it.
