BMW Integrated Supply Module Repair – Part No. 8600358-02

This is a component-level repair service for the BMW Integrated Supply Module (ISM), part number 8600358-02. This module is a common failure point in several BMW models and is responsible for distributing and protecting various power circuits throughout the vehicle.

Common faults include:

• No power to one or more fused circuits

• Intermittent or permanent loss of power to key vehicle systems (lighting, ignition, fans, etc.)

• Blown fuses with no apparent cause

• Internal relay or power driver failure

• Burnt PCB tracks or damaged components

Our repair service includes:

• Full strip-down and inspection of the ISM

• Diagnosis of failed components (MOSFETs, relays, PCB damage, etc.)

• Replacement of faulty components with high-grade automotive equivalents

• Thorough bench testing under simulated load conditions

• Protective coating applied to vulnerable PCB areas where necessary

This repair is far more cost-effective than replacement and allows you to keep the original module matched to your vehicle.
