Hello johu, in the meantime I was able to find a replacement LDU. After installing the Openinverter LDU drop-in logic board from the first LDU, I now have the same result. Tmphs shows 100°C. Could the drop-in board have a malfunction?
Thanks for the tip with the cooker element!

hello all I am trying to get my LDU (in the removed state on the table) to work. The temperature tmphs is stable already at 100°C when switched on. udc shows 7.9V, but is disconnected from the HV batterie. (four times 12V starter batteries) Engine temperature tmpm reads 12°C, which is realistic. Whe...

no, it's not Jonny!
thanks johu for clarification!

Hello, Is it correct that the ZE0 BMS has only white connectors and the ZE1 has a gray and a black connector? can the two modules be interchanged? Or what are the technical differences between the two BMS? Are the CAN bus messages different?
thank you
