BMW MSD80, MSD81, MSV80, MSV81 DME EWS Delete | Immobilizer Off ECU IMMO OFF Service
BMW MSD80, MSD81, MSV80, MSV81 DME EWS Delete | Immobilizer Off ECU IMMO OFF Service
BMW MSD80 MSD81 MSV80 MSD85 DME EWS / CAS Delete | Replacement DME Programming
This is a mail-in DME programming service for supported BMW models equipped with MSD80, MSD80.2, MSD81, MSD81.2, MSV80, MSV80.1, and MSD85 DMEs.
This service is designed primarily for DME replacement. The immobilizer authorization requirement within the DME is disabled, allowing a compatible used or replacement DME to operate without normal EWS/CAS immobilizer matching.
This is ideal when your original DME has failed and cannot be cloned, when installing a compatible used replacement DME, or when preparing a compatible spare DME.
When to Use This Service:
- You’re replacing a faulty DME that cannot be cloned due to water damage, communication failure, or other damage.
- You need to install a compatible used or replacement DME without normal EWS/CAS immobilizer matching.
- You need a spare or backup DME that can be used without matching it to the vehicle's CAS system.
What This Service Does:
- Disables the EWS/CAS immobilizer authorization requirement within the DME.
- Allows a compatible used or replacement DME to operate without normal DME/CAS immobilizer matching.
- Eliminates the normal immobilizer matching requirement when replacing the DME.
CAS Information:
On CAS-equipped vehicles, the existing CAS module and working key remain in the vehicle. This service only modifies the immobilizer authorization requirement within the DME.
It does not remove the CAS module, program keys, or repair a faulty CAS system.
Important — BMW X3 E83
BMW X3 E83 applications equipped with a separate EWS immobilizer module require a different service.
If you have an E83 X3 with MSV80 / MSV80.1, please use our dedicated BMW X3 E83 MSV80 / MSV80.1 DME EWS Delete / Immobilizer Off Service instead.
Important Notes:
- This service is intended for DME replacement or spare DME applications.
- A compatible replacement DME is required when replacing the original.
- This service does not include key programming, CAS repair, or diagnosis of other no-start conditions.
- EWS/CAS-related diagnostic fault codes may remain stored after programming but typically do not illuminate the check engine light.
- Clear all diagnostic trouble codes after installation.
- Please provide your vehicle information and DME part number with your order.
Supported DME / Engine Types:
N54 and N53 Engines
- MSD80
- MSD81
N51 and N52N Engines
- MSV80
- MSV80.1
N43 Engines

Compatibility is determined by the DME type and application, not vehicle model or model year alone.
Why Choose This Service?
- Install a compatible used or replacement DME without normal EWS/CAS immobilizer matching.
- Replace a failed DME even when the original cannot be cloned.
- Prepare a compatible spare or backup DME.
- Avoid the additional immobilizer matching normally required when installing a replacement DME.

General FAQ
See All
What is immo off or immobilizer delete, and will it work for my VW or Audi?
Immobilizer delete (immo off) bypasses the immobilizer in the engine control unit (ECU) of VW and Audi vehicles. It’s used when the vehicle starts but immediately shuts down due to a fault in the immobilizer system, often with fault codes P1570 or P0513. Immo off services will not work if the vehicle does not start at all; it must start and then be shut down due to the immobilizer.
What is module cloning, and do part numbers need to match?
Module cloning involves copying all the data from one module to another, allowing the replacement to function just like the original. While it's generally recommended to match part numbers for compatibility, the necessity can vary by module. Some require exact matches, while others are more flexible and allow cloning between different part numbers. Each product listing on our website specifies the part number requirements. If you're unsure, feel free to reach out for guidance.
Do you have to open the module cases?
We only open module cases when absolutely necessary. For services that don’t require opening, we won’t open the module. However, depending on how badly damaged your original ECU is, sometimes opening the module is the only way to retrieve data. Additionally, some services don’t have a plug-in method at all and require direct access to the board, including soldering or chip replacement. The need to open modules is not specific to us but is sometimes essential depending on the condition of the ECU.
What are the shipping procedures and turn around times?
After purchasing, you will receive an email with shipping instructions. You are responsible for shipping your modules to us, and we will cover the return shipping. You can use any shipping service that is convenient for you. We typically use UPS Ground (3-5 days) for return shipping, but in some cases, we may use USPS or FedEx. Once we receive your package (shipping times depend on how quickly you ship it and the service used), we typically ship it back the next business day. Some services may require a 2-day handling time, depending on the complexity.
For detailed shipping times to and from your location, check out our shipping speed map.
What is the warranty?
We offer a 90-day warranty on programming only. This covers the accuracy of the programming performed, but does not extend to the module hardware itself.
