2022 BMW X1 Active Cruise Control Deactivated SIB 66 06 25

Owners of the 2022 BMW X1 (U11 Sports Activity Vehicle) may experience an issue where the "Active Cruise Control" system automatically deactivates while driving. This deactivation is typically accompanied by a white Check Control Message (number 914) on the instrument cluster, stating "Limited Driver Assistance". This service bulletin, SIB 66 06 25, provides a solution for this specific problem affecting the 2022 BMW X1 Active Cruise Control system.

Symptoms

The primary symptom is the automatic deactivation of the "Active Cruise Control" system. When this occurs, a white Check Control Message will appear, displaying "Limited Driver Assistance". This can happen if the accelerator pedal is actuated very lightly while the "Active Cruise Control" is active and the vehicle transitions into an overrun (coasting) mode.

Fault Codes / DTCs

When the 2022 BMW X1 Active Cruise Control issue occurs, the vehicle's diagnostic system may store the following fault codes:

• 030845: "Cruise control with brake function not available"
• 030847: "Active Cruise Control function not available"

These codes indicate that the cruise control functionality, including its braking capability, has become unavailable due to the underlying software issue.

Diagnosis / Trigger Conditions

The problem is linked to specific driving conditions where the accelerator pedal is pressed very lightly while "Active Cruise Control" is engaged and the vehicle enters an overrun state. This sequence of events can lead to the deactivation of the 2022 BMW X1 Active Cruise Control system.

To diagnose the issue, a BMW technician will first determine the vehicle's current I-level (integrated software level) using applications like AIR or the Key Reader/AWP. They will also read out the fault memory using the ISTA diagnostic system. If the vehicle's I-level is already at or above 22-11-500, further standard diagnosis will be performed. However, if the I-level is lower than 22-11-500 and relevant fault memory entries (like 030845 or 030847) are present, the vehicle will proceed to the repair step.

Repair Procedure Summary

The core of the repair involves updating the Digital Motor Electronics (DME) software. If the vehicle's current I-level is below 22-11-500, the technician will program the vehicle to I-level 22-11-500 or higher. This process includes:

1. Connecting a BMW-approved battery charger to the vehicle to maintain stable voltage during programming.
2. Connecting the programming system, ISTA 4, to the vehicle.
3. Determining and accepting the measures plan, which outlines the required programming and encoding for all affected control units.
4. Following any specific rework lists.
5. After programming, performing a vehicle test and clearing any remaining fault memory.
6. Finally, checking the full functionality of the system to ensure the 2022 BMW X1 Active Cruise Control system operates correctly.

The repair code associated with this service action is 6600051100, which covers the activation of radar-based ACC (active cruise control) for occasional failures.

Important Warnings

Owners should be aware of several important points regarding this service:

• Battery Charger Requirement: Technicians are instructed to "Always connect a BMW-approved battery charger/power supply (SI B04 23 10)" to the vehicle during programming to prevent issues.
• Invoicing: If other programming and encoding Technical Campaign repairs are open on the vehicle, the programming and encoding procedure for this issue may only be invoiced one time.
• Warranty Coverage: If the conditions for applying other Technical Campaigns do not apply, the BMW software solution is covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks, or the BMW Certified Pre-Owned Program.

Owner Action

If you own a 2022 BMW X1 and are experiencing the "Active Cruise Control" deactivation with the "Limited Driver Assistance" message or believe your vehicle may be affected by fault codes 030845 or 030847, you should contact your authorized BMW dealership. They can perform the necessary diagnostic checks and software update to resolve the issue. This software update is typically covered under warranty.
