Mercedes W118 CLA

W118 diesel with ECU MRD1 2021. SCR disabling is not possible as the ECU has a high degree of protection, if you need to reset the SCR, do you need to do the same as for CR43 from SCRM and ECU or is there a special procedure?

You may have to downgrade your ECU first and then you can get rid of AdBlue.

When these ECUs are locked there is no solution. I need to reset with DTS Monaco and need the correct procedure.

Have you tried these steps and generated the seed keys? I think there are files on the forum to generate them.

This is for how to unlock in general with DTS Monaco and Vediamo, but I was asking steps for MRD1 to reset SCR message, I knew about CR43 and CRD3S2. But no idea about MRD1.

Sorry, I can't help you. I didn't know it was for MRD1. Hopefully you'll get lucky and someone on this forum can walk you through the steps. Best wishes.
