6. Important Notes on DME Unlocking

Depending on the production date of your vehicle, a DME bench unlock may be required to enable OBD flashing.

B58 GEN1 (USA) Cars Produced before 06/2020: May require a DME bench unlock. Check with the MHD App using the “Unlock Check Button.”
B58 GEN2 Cars Produced before 06/2020: Always require a DME bench unlock.
Cars Produced after 06/2020: Can only be tuned with a special unlock by FEMTO, requiring the DME to be sent to FEMTO in Finland.

Flashing back to stock will fully remove the FEMTO unlock, requiring the DME to be unlocked again for MHD flashing (NOT ON FEMTO UNLOCKED CARS!).

7. Understanding XDrive Delete: Why and How

XDrive, BMW’s intelligent all-wheel-drive system, enhances traction and stability by distributing power between the front and rear axles. While it’s beneficial in various driving conditions, some enthusiasts opt for an XDrive delete for specific reasons.

7.1. Reasons for XDrive Delete

Weight Reduction: Removing the XDrive system can reduce the vehicle’s overall weight, improving acceleration and handling. According to BMW, the XDrive system can add approximately 150-200 pounds to the vehicle’s weight.
Simplified Drivetrain: A simpler drivetrain can be easier to maintain and modify, appealing to those who enjoy hands-on work.
Drifting and Track Performance: Rear-wheel-drive configurations are often preferred for drifting and certain track applications, offering more predictable handling characteristics.

7.2. Methods of XDrive Delete

Software Disabling: Some tuners offer software solutions that disable the XDrive system, effectively converting the car to rear-wheel drive. This approach retains the physical components but prevents them from engaging.
Physical Removal: This involves removing the front driveshaft, transfer case, and other associated components. This method provides the most significant weight reduction but requires careful planning to ensure proper vehicle operation.

Important Considerations: Deleting or disabling XDrive can affect the vehicle’s handling and stability, especially in adverse weather conditions. It’s crucial to understand the implications and ensure the modifications are suitable for your driving style and environment.
