2022-2024 BMW EVAP System Micro-Leak SIB 16 01 23

BMW has issued Service Information Bulletin (SIB) SI B16 01 23 (Revision 1, dated January 5, 2024) to address micro-leaks within the fuel evaporative (EVAP) system. This bulletin supersedes the previous version, SI B16 01 23 dated June 2023, with updated claim information. The issue primarily affects various 2022-2024 BMW models equipped with the Natural Vacuum Leak Detection (NVLD) system.

Symptoms

Owners may notice their vehicle being diagnosed for a micro-leak in the fuel evaporative (EVAP) system. This condition is specifically related to the NVLD system.

Fault Codes / DTCs

The primary diagnostic trouble code (DTC) associated with this condition is:

• 190302: "fuel tank ventilation and scavenging air system, micro-leak: leakage more than 0.5 mm"

This fault code indicates that a micro-leak, specifically greater than 0.5 mm, has been detected in the fuel tank ventilation and scavenging air system.

Diagnosis

When a vehicle presents with a 2022 BMW X5 EVAP micro-leak, technicians will perform a diagnosis for the micro-leak in the EVAP system. If the fault code 190302 is stored in the Digital Motor Electronics (DME), it confirms the presence of a micro-leak. For other EVAP faults or larger leaks, technicians are instructed to first confirm the fuel filler cap is properly fitted, then follow the corresponding test plan.

Repair Procedure Summary

The repair process involves using specialized tools and diagnostic software to pinpoint and address the micro-leak. Technicians will:

1. Utilize the Micro-leak detector tool (B04 02 22).
2. Follow the ISTA test plan ABL-DIT-AS1214_BX8_DHP_NVLD3-Natural Vacuum Leak Detection leakage test-V.3.
3. Refer to Video V160122 for guidance on setting up and operating the NVLD test tool if needed.
4. Depending on the diagnosis, replace specific components such as the venting line with the leak diagnosis module (NVLD), fuel tank breather valve, or fuel tank ventilation valves with pipes.
5. If applicable, the carbon canister with an attached NVLD may also be removed or replaced.

Required Tools and Parts

Technicians will require specific tools and parts for this repair:

• Micro-leak detector tool (B04 02 22)
• Special tool kit (PN 83 30 5 A39 389) for NVLD/Purge Valve “micro leaks” diagnosis
• Venting line with leak diagnosis module (NVLD)
• Fuel tank breather valve
• Fuel tank ventilation valve with pipe (1-4)
• Fuel tank ventilation valve with pipe (5-8)
• Carbon canister (if replacement is necessary)

Additional materials like fluids, lubricants, and one-time use fasteners may also be required, as specified by ISTA repair instructions or the Electronic Parts Catalog.

Claim Information

Repairs performed under this bulletin for a verified defect in materials or workmanship are covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks, which includes the Emissions coverage. The bulletin specifies various labor operations and repair codes for submitting claims, including:

• Repair Codes: 1613111200 (Fuel tank leak diagnostic module NVLD Permanent failure) and 1390011500 (Tank ventilation valve Permanent malfunction).
• Labor Operations: 00 00 006, 00 00 556, 61 21 528, 61 00 006*, 00 58 500*, 13 90 500, 13 90 509, 16 13 523, 16 12 510, 16 13 525, and 16 00 510.

For documenting and claiming diagnosis work time, technicians are advised to refer to SI B01 01 20 or B01 07 20.

Important Notes for Owners

Owners should be aware that it is crucial to review the VIN-specific Vehicle Comment section in the Warranty Vehicle Inquiry. This section will provide notifications of any applicable component-specific extended limited warranty (ELW) coverage that may apply to your vehicle. This ensures you are aware of any additional coverage for this 2022 BMW X5 EVAP micro-leak issue.
