About This Service
The Direct Select Module (DSM) is a key component in Mercedes vehicles equipped with the FBS4 Drive Authorisation System.
It handles communication between the gearbox, engine ECU, and immobiliser system.
When faulty, it can cause transmission errors or starting issues.
Our Mercedes DSM Swap service provides a tested replacement DSM programmed with your vehicle’s original data — fully plug-and-play on arrival.
Important Notes
- This service is for customers whose DSM has been confirmed faulty by a qualified garage or auto-electrician.
- We do not supply DSMs for testing purposes. Returns are only accepted if the DSM supplied is faulty.
- Your original DSM must still have diagnostic communication for cloning.
If your DSM is completely dead, we can still supply a plug-and-play DSM at additional cost. - We also supply virginised (factory-reset) DSM units which will require programming to your car using dealer or professional diagnostic tools.
