SITUATION
BMW AG has issued a Delivery Stop (effective December 1, 2022) on certain Model Year 2023 BMW iX
SAV vehicles that were produced between October 5, 2022 and November 10, 2022.
A bearing in the front electric drive unit could fail due to a manufacturing defect, resulting in a noise while
driving.
CORRECTION
Replace the front electric drive unit (aka “HEAT”, which stands for the German acronym for Highly integrated
electric drivetrain topology- Hochintegrierte Elektrifizierte Antriebs-Topologie)
PROCEDURE
Important Warning for Working on the High-Voltage (HV) systems on BMW Group vehicles:
Only properly trained personnel, who passed all applicable HV Technical Training Courses, should
perform repairs which require disconnecting, or removal of High Voltage battery components on any
Hybrid or Electric Vehicle. Work performed on High Voltage systems by unqualified persons may
result in severe injury or damage to the vehicle. Additional safety information is found in Repair
Instruction 61 00… “Observe safety instructions when handling electric vehicles”.
Additional Information:
Scheduled Maintenance, or Quality Certification 1 (Pre-Delivery Inspection) on Electric or Hybrid
vehicles does not require HV technical training.
Prior to disconnecting, or the removal of any HV component, the HV system needs to be disabled
and secured (by means of the HV Disconnect Switch) by a properly trained technician, who has a
minimum HV Qualification level after completing the Technical Training Course ST1824 (Alternative

Drive Part 1). Once the vehicle’s HV system is disabled (the “Blitz” – lightning bolt icon displayed in
instrument cluster, see below), a technician without HV Certification may remove a HV component
(e.g., EH Heater, EKK Compressor, EME Control Unit, et.), except for the High Voltage Battery.
High Voltage Battery removal and rework can be performed ONLY by a HV Specialist Technician
(certified by the Technical Training Course ST1825 – Alternative Drive Part 2), AND with a HV Battery
Certification level corresponding to a specific Electric or Hybrid vehicle (e.g., to repair GEN4 battery
of G05 PHEV, certification from Technical Training Course “ST2006 – SP44 HV Battery” is required).
Therefore, to perform this SIB 12 04 22, a GEN5 battery Certification is required from Technical
Training Course “ST2205 Generation 5 High-voltage” class).
The complete front electric drive unit is replaced; see repair instructions 12 35 521 “Replace front highlyintegrated electric drive topology completely (after vehicle diagnosis)”.
Important Note:
The replacement front electric drive unit comes pre-filled with fluid, eFluid transmission oil
PN 83 22 5A1D718.
Contrary to the repair instructions, there is no need for a wheel alignment and replacement of the
radial shaft seals. The repair instructions will be updated accordingly with the next release.
PARTS INFORMATION
Please refer to the Parts Matrix for the most up-to-date ordering information.
