Hi
Sorry for the late reply
I have a Fault codes for my BMS and sent my BMS our for repairs (was not cheap). Once that was back it was told that it had common problems and guaranteed that all is fix within the BMS. After installing the BMS back into the HV battery and started to see signs of life again as I did a quick initial start up and shut down so I can clean up and get moving. Little did I know there was a few more fault codes. These fault codes are apparently linked to the current sensor, I had a few mechanics checked the codes, clear it and it still there, looked around online and found info on the link u posted as it was the same codes as that, then sent the same codes to person that repaired my BMS and he also confirm it’s the current sensor is bad.
I called friends at Benz/Smart and no luck as they don’t sell that sensor by itself, called Bosch and they don’t sell it to anyone as it’s licensed to Smart/Benz only. So here I am looking for a good used one in hopes that it will fix my problem.
Removing and disassembling the HV battery is not fun. Did it 3 times already. If anyone attempts this. Be VERY careful.
