Bosch MG1-MD1-MG1-MRD1-MRG1 ECU Remote Unlock

1 min readBy JF AutomotiveMaidstone, Kent

2020-On BMW and Mercedes ECU's can now be unlocked!

HOW THE UNLOCK WORKS?

 

We’re excited to launch support for Bosch MD1CP001 (MRD1) and MG1CP002 (MRG1) ECUs in modern Mercedes models. Best part? No ECU opening needed for this Remote Unlock! 🚀

 

How it works:

  1. Bring the vehicle in or ship us the ECU.
  2. We confirm ECU eligibility with BENCH identification check ✅ (Some versions still can’t be unlocked)
  3. We send your ECU to our Autotuner (Tool developer) HQ for Remote Unlock. 📦
  4. ECU gets unlocked and returned to us, ready for BENCH & OBD tuning by us. 🔓

⚠️ Note: ECU returns to stock; prior tuning will be erased permanently. Good news: Dealership updates won’t affect the Remote Unlock. 👍

⏱️ The whole process takes approximately 5 working days.

You can do it in your own workshop with Autotuner, or send us the read and we will build the file. Custom tuning file service Finance and lease What bench tuning means File prices See the Autotuner →
