Have a failed, water-damaged, corrupted, or non-communicating BMW MSD85.1 or MSD85.3 DME/ECM?

You send us your original MSD85 DME, original CAS module, and one working vehicle key. We provide a compatible remanufactured MSD85.1 or MSD85.3 DME, transfer the applicable vehicle-specific data, professionally bench test the replacement, and ship everything back to you.

YOU SEND YOUR DME + CAS + KEY — WE PROVIDE THE REMANUFACTURED DME

No donor DME required.

Every remanufactured MSD85 supplied through this service includes our 3-Year Warranty.

SUPPORTED DME TYPES

• BMW MSD85.1
• BMW MSD85.3

Exact compatibility depends on the original DME part number, hardware/software version, engine, production date, and vehicle configuration.

If you're unsure, send us a clear photo of your original DME label and VIN before ordering.

COMMON MSD85 FAILURE SYMPTOMS

A failing MSD85 may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine stalling
• Rough running or misfires
• Injector or ignition-related faults
• Reduced power / limp mode
• No communication with DME
• Intermittent DME communication
• Internal DME faults
• Corrupted software/data
• Water or moisture damage
• Complete DME failure

Proper diagnosis is recommended because wiring, sensors, injectors, ignition components, power supplies, grounds, and other vehicle systems can produce similar symptoms.
