You send us your original E38 ECM, and we provide a compatible remanufactured E38 replacement ECM. We transfer the applicable vehicle-specific data and configuration, professionally program and bench test the replacement, and return it ready for installation where supported.

COMMON E38 ECM FAILURE SYMPTOMS

A failing E38 may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine stalling
• Rough running / misfires
• Reduced engine power

• Intermittent communication
• Injector / ignition faults
