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.
