2023-2024 BMW i7 High-Voltage Cable Abrasion Service Action

Important Warnings

BMW has issued a critical advisory regarding vehicles affected by this service action. Dealers are instructed: "Do not deliver to a customer, a New, Certified Pre-Owned or Used vehicle subject to a Delivery Stop, until the vehicle is repaired. Do not use or sell replacement equipment/parts subject to a Delivery Stop."

Additionally, working on high-voltage (HV) systems in BMW Group vehicles requires specialized training. Only properly trained personnel who have passed applicable HV Technical Training Courses should perform repairs that involve disconnecting or removing High Voltage battery components. Performing such work without proper qualification can result in severe injury or damage to the vehicle. The HV system must be disabled and secured by a properly trained HV technician before any HV component is disconnected or removed.

Symptoms

Owners of affected 2023-2024 BMW i7 vehicles may notice a specific warning message on their instrument cluster. The primary symptom associated with this issue is a "Check Control message 'Drive faulty'" appearing on the dashboard. This message indicates a potential problem with the electric drive unit.

Cause of the Problem

The root cause of the "Drive faulty" message in the 2023-2024 BMW i7, as identified in Service Information Bulletin SIB 61 16 24, is the chafing of the rear high-voltage cable for the electric drive unit. This abrasion can compromise the cable's integrity, leading to the warning message.

Repair Procedure Summary

To address the BMW i7 high-voltage cable abrasion, technicians will perform a specific service action. The procedure involves inspecting the high-voltage cable for the rear electrical machine for any signs of chafing or damage. If damage is found, the cable will be replaced. Regardless of whether damage is present, retrofit abrasion protection will be installed as required. The repair process references instruction REP 61 12 477, which details the removal and installation of the rear electrical machine high-voltage cable.

It is important to note that if a replacement high-voltage cable with an index Al08 is installed, abrasion protection must be retrofitted. However, if a cable with an index Al09 or higher is used, the abrasion protection is already integrated and does not require additional retrofitting.

Required Parts

The following parts may be required for this service action:

• 61 29 5 B5B BE9: Repair cable
• 61 12 5 A37 103: High-voltage wiring harness (if required)

Additional materials and small parts, such as fluids, lubricants, one-time use screws, nuts, and seals, will be selected from the Electronic Parts Catalogue or other approved BMW Group resources as needed.
