2024 BMW i5 Distance Recorder Issue SIB 34 01 24

Symptoms

Owners of affected 2024 BMW models, including the BMW i5 distance recorder, might notice that the total distance covered by their vehicle appears lower than expected after the Integrated Braking system (IB) or Power Brake unit has been replaced. This discrepancy is due to an issue with the vehicle's internal mileage recording.

Cause

The vehicle's distance recorder reading is regularly backed up. When the Integrated Braking system (IB) is replaced, an automatic plausibility check occurs between the new IB unit and the Body Computing Platform (BCP). If the original vehicle distance recorder data from the BCP was not successfully transferred to the new IB unit during the replacement, the displayed mileage can be incorrect.

Important Warnings

BMW Service Information Bulletin SIB 34 01 24 includes several critical advisories for technicians and owners:

• If the vehicle's software (I-level) is already at or above the target integration level (e.g., S18A-24-11-530, G070-24-11-530, U006-24-11-530), technicians are instructed "do NOT program the vehicle and instead continue to Step 4."
• When documenting the current odometer reading for the TSARA case, a photo of the odometer is required. BMW states: "The vehicle must not be moved after this photo to ensure current mileage accuracy."
• After the IRAP (Integrated Repair and Programming) operation, the displayed mileage in the odometer will only update after a 1-hour sleep cycle. It is crucial that "The vehicle MUST NOT be moved or driven until the new corrected mileage has been adopted or the mileage correction process will fail!"
• When submitting a TSARA case, selecting the correct case type, "Repair Clearing", and priority, "Reply Requested", is essential. BMW warns that "Any other case type will cause a delay in case response" and "Any other priority type will cause a delay in case response."

Repair Procedure Summary

The correction for the BMW i5 distance recorder issue involves programming the vehicle to a specific integration level (I-level) or higher. This Service Information Bulletin, SIB 34 01 24, outlines the following steps for technicians:

1. Document Current Odometer: Start an ISTA session to document the current odometer reading in the backend. This is for documentation only; no diagnosis is needed at this stage.
2. Check Software Level: Verify if the vehicle's I-level is already at or above the required target (e.g., S18A-24-11-530, G070-24-11-530, U006-24-11-530). If it is, programming is not required, and the technician proceeds to Step 4.
3. Program Vehicle: If the software level is below the target, the vehicle must be programmed to ISTA version 4.50.3 (released November 12, 2024) or higher. This involves connecting the programming system, determining the measure plan, accepting the plan, following the rework list, and performing a vehicle test to clear any fault memory.
4. Submit TSARA Case: A TSARA case must be submitted with the subject line "SA: 34040300 Distance Recorder". The case type must be "Repair Clearing" and the priority "Reply Requested".
5. IRAP Setup: Set up the vehicle for IRAP as per SI B09 02 16 and SI B09 01 16.
6. Mileage Update: After IRAP completes, the mileage will not visibly change until the vehicle undergoes a 1-hour sleep cycle. The vehicle must remain stationary during this time.
7. Final Documentation: Update the TSARA case with the final odometer results and a picture of the odometer to confirm the correction.
8. Final Vehicle Test: Perform a follow-up vehicle test with ISTA to clear any remaining faults before returning the vehicle to the customer.

Required Tools or Parts

No specific parts are required for this repair, as indicated by the bulletin. However, the procedure necessitates the use of the ISTA diagnostic and programming software, specifically version 4.50.3 or higher. Technicians must also ensure a BMW-approved battery charger/power supply is connected throughout the programming process, as detailed in SIB 04 23 10.

Owner Action

If you own a 2024 BMW i5 or other affected model and suspect an incorrect distance recorder reading after an Integrated Braking system replacement, you should contact your authorized BMW dealership. This Service Action, identified by SIB 34 01 24, is performed under warranty. The dealership will check your vehicle's software level and perform the necessary programming and updates to correct the BMW i5 distance recorder reading. It is important to ensure the vehicle remains stationary during the mileage correction process as instructed by BMW.
