2024 BMW X5 Spark Plug Service Interval Correction

BMW has released Service Information Bulletin SIB 62 02 25 to address an issue affecting the spark plug replacement interval displayed in the Condition Based Service (CBS) system for certain vehicles equipped with the S68T engine. Owners of affected models, including the 2024 BMW X5, may notice that their vehicle's CBS data suggests spark plug replacement is due significantly earlier than the recommended schedule.

Symptoms

The primary symptom owners will observe is the Condition Based Service (CBS) system indicating that spark plug replacement is required at a considerably "earlier" interval than expected. This premature notification can lead to unnecessary service appointments or confusion regarding maintenance schedules for your 2024 BMW X5 and other affected models.

Cause

The root cause of this issue is incorrect data stored within the Condition Based Service (CBS) system regarding the spark plug replacement interval. Specifically, the initial mileage for spark plug replacement was erroneously set to approximately 15,000 miles (25,000 km) instead of the correct interval of 40,000 miles (60,000 km).

Important Warnings

BMW explicitly states that "Spark plug replacement SHOULD NOT be performed in the affected vehicles before the proper interval, regardless of the CBS display." This is crucial to prevent premature and unnecessary maintenance. If your vehicle's CBS data shows an early spark plug interval, do not proceed with replacement until the CBS data has been corrected.

If a spark plug replacement was already performed on a vehicle with over 14,000 miles, technicians are advised to check the vehicle's history. If the spark plug replacement was performed and the CBS data was previously reset, no further action is needed. The Service Information Bulletin SIB 62 02 25 clarifies that only the initial CBS spark plug interval was incorrect.

Repair Procedure Summary

The correction for the incorrect 2024 BMW X5 spark plug interval involves resetting the CBS data using the ISTA diagnostic system. This procedure ensures the spark plug maintenance interval is set to the correct value. Here's a summary of the steps technicians will follow:

1. Connect to ISTA: The diagnostic system is connected to the vehicle.
2. Vehicle Identification: The vehicle is identified without performing a full vehicle test.
3. Navigate Service Functions: Technicians will select "Vehicle Management," then "Service Functions," and finally "Maintenance and Pre-Delivery Check."
4. Battery Charger: A BMW-approved battery charger/power supply (referencing SI B04 23 10) must be connected to the vehicle throughout the process.
5. Reset CBS Data: The test plan ABL-WAR-AS6100_CBS_RESET – "Reset CBS Condition Based Service" is selected. The spark plug service value is reset within this test plan.
   • Note: The bulletin mentions a known error in ISTA where a warning might appear stating the reset was "not performed," even if successful. This error is expected to be fixed in ISTA version 4.52.2x (estimated release date of March 4, 2025).
6. Correct CBS Data: Next, the test plan ABL-WAR-AS6100_CBS_KORR – "CBS Vehicle Data Correction" is selected. The values for spark plug service are corrected here, as no actual spark plug replacement has occurred.
7. Re-enter Maintenance Values: The option to "Re-enter the values for Maintenance Work" is chosen.
8. Mileage of Last Service: For "Mileage of Last Service," the value "0" is entered, indicating that no spark plug replacement has taken place.
9. Service Counter Adjustment: The service counter will automatically reduce to 1. If prompted to alter the Service Counter further, the technician will select "No."
10. Verification: After the process, the vehicle is allowed to enter a sleep cycle, and the display is rechecked to ensure the "Spark Plug Maintenance Interval will not display in the vehicle unless the service is triggered as 'Due'" and has reset to the correct value.

Required Tools or Parts

This service action primarily requires the use of the ISTA diagnostic system and a BMW-approved battery charger/power supply, as specified in SI B04 23 10. No specific replacement parts are needed, as the repair involves a software-based data correction.

Claim Information

Reimbursement for this Service Action, identified by Repair Code 0062600100, is handled via normal claim entry. Technicians will use specific work package information depending on the scenario:

• Work Pkg #1 (00 77 732): For completion before first vehicle delivery or when the vehicle is already in the workshop for another reason.
• Work Pkg #2 (00 77 169): When the vehicle arrives specifically for this Service Action and no other main work is performed.
• Work Pkg #3 (00 77 734): When the CBS data correction is performed in conjunction with another technical campaign or repair.

Only one flat rate labor operation code can be claimed per workshop visit. The SIB number, SIB 62 02 25, and the work package number should be referenced in technician notes and claim comments.
