2024 BMW X5 Engine Cranks But Won't Start Service Action

BMW has released Service Information Bulletin (SIB) 16 01 24 to address a specific starting issue affecting several 2024 models, including the 2024 BMW X5. Owners may experience a condition where the engine cranks but will not start. This service action involves reprogramming the vehicle's control units to correct the underlying software fault.

This bulletin, identified by the repair code 0016840200, ensures that affected vehicles receive the necessary software update to prevent starting problems. If your 2024 BMW X5 engine cranks but will not start, your dealership will perform this service.

Symptoms

The primary symptom owners will notice is that the "engine cranks but will not start." This indicates that while the starter motor is engaging and turning the engine over, the engine is not igniting and running on its own power.

Cause

The root cause of the problem lies with the control unit responsible for the fuel pump, known as the Integrated Fuel Management (IFM) or Tank Function Electronics (TFE). During evaporative emissions monitoring, this control unit may go into a sleep mode. This can lead to a data error that prevents the TFE/IFM from communicating correctly when the vehicle is started, resulting in the engine failing to start.

Repair Procedure Summary

To correct the issue where the 2024 BMW X5 engine cranks but will not start, technicians will perform a software update. The procedure involves several key steps:

1. Determine Current I-level: The technician will first determine the vehicle's current integration level (I-level) using BMW's diagnostic applications, AIR or ISPA NEXT/AWP (Aftersales Workplace).
2. Reprogramming: The vehicle will then be programmed using ISTA 4.40.5x software or a higher version, which was released in February 2023. This process will update the IFM/TFE control unit.
3. Target Integration Levels: Specific target integration levels must be achieved depending on the vehicle model:
   • For G05 (X5), G06 (X6), G07 (X7) models: S18A-23-11-525 or higher.
   • For G60 (5 Series Sedan), G70 (7 Series Sedan) models: G070-23-11-520 or higher.
   • For U11 (X1) models: U006-23-11-525 or higher.

It's important to note that ISTA will automatically reprogram and code any other programmable control modules that do not have the latest software during this process. The service action is identified by SIB 16 01 24 and repair code 0016840200.

Important Warnings

When performing any programming, technicians are instructed to "Always connect a BMW-approved battery charger/power supply (SI B04 23 10) when performing programming." This ensures stable voltage during the critical software update process, preventing potential damage to control units.

Claim Information

BMW provides specific labor operation codes for dealers to claim reimbursement for this service action. These include:

• 00 75 826: For programming and encoding vehicle control units, including a vehicle test (referencing 00 00 556/61 21 528).
• 00 75 827: For programming and encoding performed in conjunction with another campaign or repair, where the vehicle is already at the target integration level.
• 00 75 246: For programming and encoding vehicle control units for vehicles arriving at the service center, including a vehicle test (referencing 00 00 006/61 21 528).
• 00 75 247: For programming and encoding performed in conjunction with another campaign or repair for vehicles arriving at the service center, where the vehicle is already at the target integration level.
• 00 75 848: Additional work for resetting the control unit if there's a no-start situation or no communication with the TFE.

Dealers are advised to refer to SI B01 01 20 or SI B01 07 20 for proper documentation and claiming procedures related to diagnosis work time.

Owner Action

If you own a 2024 BMW X5, X6, X7, 5 Series, 7 Series, or X1 and experience the "engine cranks but will not start" symptom, you should contact your authorized BMW dealer. They will be able to check if your vehicle is affected by Service Information Bulletin SIB 16 01 24 and perform the necessary software update to resolve the issue. This repair will typically be covered under warranty as a service action.
