Understanding the BMW Condition Based Service System

The 2017 BMW M240i xDrive Convertible is equipped with the Condition Based Service (CBS) system, which represents a significant evolution from traditional fixed-interval maintenance. Sensors and algorithms monitor the vehicle's operating conditions, and the CBS system uses this data to calculate maintenance requirements. This allows the system to adapt the amount of maintenance needed to your specific user profile.

The system monitors factors such as driving style, fuel consumption, and trip length to determine when maintenance is actually needed. This results in variations from traditional fixed intervals, meaning two identical vehicles may require service at different odometer readings depending on how they have been driven. Because the CBS system is the primary guide for your specific vehicle, the reference intervals provided below should be used for planning purposes, but the CBS system remains the primary indicator for when service is required.

Factory Maintenance Coverage

The 2017 BMW M240i xDrive Convertible originally came with comprehensive factory coverage:

Service Interval Summary

Engine Oil and Filter Service

The CBS system is the primary indicator for oil change intervals, with service timing varying based on driving conditions. Pelican Parts recommends changing synthetic motor oil every 5,000 miles as a conservative practice for the B58 engine . Always replace the oil filter when changing the oil.

Approved Oil Specifications:

  • BMW LL-22 FE++
  • BMW LL-17FE+
  • BMW LL-01

Available Viscosities:

  • Various viscosities are approved for this engine. Always refer to your owner's manual for the exact viscosity recommendation for your specific vehicle and climate.

Brake Fluid Service

Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of the braking system . The 2017 M240i requires brake fluid meeting DOT 4 specifications . Genuine BMW brake fluid is a low-viscosity formula designed for the vehicle's braking system .

Brake fluid should be changed according to the CBS system or at regular intervals. Checking your owner's manual will confirm the specific brake fluid requirements for your vehicle .

Spark Plug Service

The 2017 BMW M240i uses NGK spark plugs as original equipment . Replacement intervals are determined by the CBS system based on driving conditions.

Transmission Fluid Service

The ZF 8-speed automatic transmission is a sophisticated unit that requires brand-specific transmission fluid . The transmission is one of the most neglected service areas on a vehicle . Automatic transmission fluid assists in more than just lubrication—it also supports the operation of brake bands, torque converter, and valves .

Transmission Fluid Notes:

  • The ZF 8-speed transmission requires fluid compatible with Lifeguard 8
  • Check your owner's manual for the exact fluid specification
  • Consider periodic fluid service as a preventive measure

Fuel System Maintenance

For vehicles with direct injection (GDI) engines, periodic fuel system cleaning is recommended. Products are available that remove carbon deposits from intake valves, fuel distributors, and injection valves . Regular use can help prevent Low Speed Pre-Ignition (LSPI) and protect the fuel system from corrosion .
