BMW NBT Evo ID5/6 FSC Code Repair Pack: Retrofitting ATM for ConnectedDrive Services

Upgrading your BMW’s infotainment system can unlock a host of modern features, and retrofitting the ATM (Automotive Telematics Module) is a popular modification to enable ConnectedDrive services on older NBT Evo ID5/6 systems. However, a common challenge arises due to FSC (Freischaltcode) codes and VIN (Vehicle Identification Number) mismatches. This article explores a solution using a CAN filter and specific coding procedures to successfully retrofit an ATM module and activate ConnectedDrive services without requiring a complete FSC kit replacement.

Understanding the ATM Retrofit Challenge

When retrofitting an ATM module, the new module often comes with a different VIN than your vehicle. This VIN mismatch can cause issues with FSC activation, as the ConnectedDrive services are typically tied to the original VIN and FSC set of your car. Traditionally, resolving this would necessitate purchasing a new FSC kit, which can be costly and complex.

The Innovative Solution: CAN Filter and Coding

This guide details a method to bypass the traditional FSC kit requirement by utilizing a CAN filter in conjunction with specific coding steps. This approach allows you to integrate a donor ATM module and activate essential ConnectedDrive services by strategically managing CAN communication and manipulating VIN associations during the coding process.

Step-by-Step Guide to ATM Retrofit and FSC Activation

This process involves a two-part coding approach, leveraging a CAN filter to manage VIN recognition at different stages of the activation.

Part 1: Initial Coding with CAN Filter (Pre-ATM Placement)

1. Prepare the CAN Filter: Initially, the CAN filter needs to be positioned between the ZGW (Central Gateway Module) and the HU (Head Unit) / ATM. Ensure the vehicle battery is disconnected before proceeding with any wiring changes.

2. Modify Vehicle Order (FA): Using coding software, edit your vehicle’s FA. Add the necessary Sales Codes (SA) relevant to the ATM and ConnectedDrive services you wish to enable. Crucially, temporarily change the VIN in the FA to the VIN of the donor ATM module.

3. Load Modified FA and Code the HU: Load the modified FA in your coding software’s expert mode (avoid writing via VCM). Proceed to code the Head Unit (HU) with this modified FA.

4. BMW Connected App Activation: Utilize the BMW Connected Smartphone app and add your donor VIN to your ConnectedDrive account. This step may take some time, but eventually, an activation code will appear within the BMW Messages menu in your iDrive system.

5. Update Services in iDrive: After successfully associating the donor VIN with your ConnectedDrive account, navigate to the ConnectedDrive menu in your iDrive system and select “Update Services” via the option button on the controller. You should now observe new ConnectedDrive functions appearing in your iDrive menu.

Part 2: Final Coding and CAN Filter Relocation (Post-ATM Placement)

1. Disconnect Battery and Relocate CAN Filter: Disconnect the vehicle battery once more. Physically relocate the CAN filter. Remove it from its initial position behind the HU and reposition it to be placed after the ATM module. Ideally, make the CAN filter pluggable behind the OABR connector on the ATM for easy access.

2. Reconnect Battery and Restore Original VIN: Reconnect the vehicle battery. Using your coding software, revert the previously edited FA. Change the VIN in the FA back to your car’s original VIN.

3. Recode the HU: Code the Head Unit (HU) again with the FA now containing your car’s original VIN.

4. Clear Diagnostic Trouble Codes (DTCs): Employ ISTA (Integrated Service Technical Application) or similar diagnostic software to clear any Diagnostic Trouble Codes (DTCs) that may have arisen during the process.

Verifying ConnectedDrive Service Activation

Following these steps, you should now be able to utilize a range of ConnectedDrive services. Typically, successfully activated services include:

• Remote Services: (Lock/unlock, light flash, climate control activation, horn)
• RTTI (Real-Time Traffic Information)
• Online Services: (Weather information, email access, Wikipedia)

Service Limitations

It’s important to note that while this method enables core ConnectedDrive functionalities, some services might not be fully operational due to the nature of the retrofit and FSC configuration. In some cases, services like Online Entertainment and the in-car CD Store may not function correctly or might display “currently not available” messages. These limitations are generally minor compared to the successful activation of essential services.

Conclusion: Cost-Effective ATM Retrofit Solution

This method provides a valuable alternative to expensive FSC kit replacements when retrofitting an ATM module to enable ConnectedDrive services on BMW NBT Evo ID5/6 systems. By strategically using a CAN filter and following a specific two-part coding process, you can unlock essential ConnectedDrive features, enhancing your BMW’s connectivity and functionality. While some minor service limitations might exist, the benefits of activated Remote Services, RTTI, and Online Services offer a significant upgrade for your driving experience.
