Hi,
today i installed my OVMSv3.3 module in my 2012 Twizy (80kmh version), connected it to dexters-web.de and the basic stuff seems to work (Dashboards, Apps etc.).
Unfortunately the tuning of my twizy isn't working or maybe I just don't know what to do. What i have done is putting the key in "before GO" position, connecting to the local AP, activated write-support and changed the profiles (settings are shown in Browser in "Drivemode-View"). I think till this point everything works well, but when i've tried to activate the profile I will get this error "CFG LOAD #0: Failed: SDO access failed". The error is similar when i try to activate profile 1,2 or 3. Am I doing something wrong? I tried to activate the profile via SHELL but i'm struggling with the syntax and had no luck with that.
Has someone got an idea?
Some additional information from the log:

That's typical for a locked SEVCON. Check the SEVCON firmware version:

Maybe the SEVCON was replaced for repair.
