2022-2024 BMW iX Radome Heating Failure Service Action

BMW has released Service Information Bulletin SIB 51 06 22, a service action concerning a potential issue with the front ornamental grille's radome heating system in certain iX Sports Activity Vehicles. This bulletin, which is Revision 2 and replaces an earlier bulletin dated October 2022, details a manufacturing defect that can cause the radome heating to fail.

The radome heating system is crucial for melting snow and ice deposits from the front grille, ensuring the proper function of the radar sensors located behind it. A failure in this system could compromise the safety and performance of these sensors, especially in cold weather conditions. This 2023 BMW iX manufacturer_communication outlines the necessary repair.

Symptoms of Radome Heating Failure

Owners of affected 2022-2024 BMW iX models may experience issues related to the front radome heating. The primary symptom is the failure of the radome heating system itself. This occurs because of a manufacturing defect that can interrupt the heater circuits within the component. When the radome heating fails, snow and ice may accumulate on the front ornamental grille, potentially obstructing the radar sensors and impairing their safe operation.

The Root Cause

The root cause of this issue is identified as a manufacturing defect within the radome heating component. This defect leads to the interruption of the heater circuits, rendering the radome heating system inoperative. The radome is defined as a weatherproof enclosure that protects a radar antenna, combining the terms "radar" and "dome."

Repair Procedure

To correct the radome heating failure, technicians are instructed to replace the cover trim that includes the radome heating. This procedure is detailed in BMW's internal repair instructions, specifically REP 51 13 000, titled "Removing and installing/replacing front grill center section." Following the replacement, it is critical that the radar sensors are calibrated. This calibration can be performed either statically or dynamically, as specified in the repair instructions, to ensure accurate sensor operation after the new component is installed. This 2023 BMW iX manufacturer_communication ensures proper repair.

Required Parts

The following parts may be required for this service action, depending on the vehicle's specifications:

• 51 11 5 A32 795: Front cover trim, bronze (Quantity: 1)
• 51 11 5 A32 789: Front cover trim, silver (Quantity: 1)
