The P8 and GND2 connections should look like this.
Do not use thin and long wires and everything should work.Comment

Apologies i managed to read it, i didnt realize if you select manual mode on this part number then you can also read eeprom, i thought i can only do it by going into omoda, so i think that was my problem, also just like omoda i must disconnect GND2 for it to work and my P8 wire is very short, only 2CM long
For anybody that is wondering what it looks like to successfully read this module, it looks like this in the log

These fault codes are present and the component is already newComment

These are just active errors on the car. Disconnect the new part and install a 2.2 ohm resistor to test.Comment

It is not monitoring the module, I disconnected components that did not detonate and it does not generate them as DTCsComment
