Have a failed, water-damaged, corrupted, or non-communicating BMW MSD85.0 or MSD85.4 DME/ECM?

Lacorte Automotive offers a professional mail-in MSD85 cloning and data-transfer service. You send us your original DME, compatible replacement DME, original CAS module, and one working vehicle key. We transfer the applicable vehicle-specific data from your original module to the replacement, professionally bench verify the completed unit, and ship everything back to you.

YOU SEND BOTH DMEs + CAS + KEY — WE CLONE THE REPLACEMENT

This listing does NOT include a replacement DME.

You must supply your original DME and a compatible donor/replacement DME.

SUPPORTED DME TYPES

This service covers supported:

• MSD85.0
• MSD85.4

These Siemens/Continental engine-management systems can be found in select BMW applications. Exact DME compatibility depends on the vehicle, engine, production date, hardware version, software version, and part number.

Please verify the identification on your original DME before ordering.

COMMON MSD85 FAILURE SYMPTOMS

A failing or damaged MSD85 may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine unexpectedly stalling
• Rough running
• Engine misfires
• Multiple cylinder faults
• Injector-related faults
• Ignition-related faults
• Reduced power / limp mode
• DME communication faults
• No communication with the DME
• Intermittent DME communication
• Multiple engine-management fault codes
• Internal processor or memory faults
• Corrupted software/data
• Water or moisture damage
• Internal electronic failure
• Completely dead DME

Proper diagnosis is strongly recommended before ordering. Injectors, ignition components, sensors, wiring, grounds, power supplies, battery voltage, fuel-system problems, and other vehicle components can produce similar symptoms.

WHAT YOU MUST MAIL IN

For this service, send:

• Original MSD85.0 / MSD85.4 DME

IMPORTANT — CAS & KEY REQUIRED

Do not send only the two DME modules.

• Flash data
• EEPROM / internal data
• VIN
• Coding and configuration

PROOF OF OWNERSHIP REQUIRED

Because this service involves vehicle-specific electronic and immobilizer information, proof of vehicle ownership is required before service is performed.

Please provide:

• Government-issued photo ID
• Vehicle title or current registration
• Vehicle VIN

Documentation must correspond with the vehicle being serviced.

IMPORTANT — REPLACEMENT DME COMPATIBILITY

A DME that looks identical is not necessarily compatible.

Compatibility can depend on:

• MSD85 variant
• BMW part number
• Siemens/Continental part number
• Hardware version
• Software version
• Engine/application
• Vehicle production date
• Vehicle configuration

If your original DME has severe physical, electrical, water, or internal memory damage, some original data may not be recoverable through the standard cloning process.

NOT SURE IF YOUR REPLACEMENT IS COMPATIBLE?

Send us:

• Clear photo of your original DME label
• Clear photo of your replacement DME label
• Vehicle year/model
• VIN

We'll help verify compatibility before you ship your modules.
