Yes, you can change it.There is a procedure you have to follow to do this with BMW repair kit that includes the sensor. You can get the procedure from the ISTA you are using under " Repair Manuals and Technical Data / 61 General vehicle electrical system / 61 27 High-voltage battery unit ...

I think only cell module 5 is okay. The temperature sensor reading should be around 80kΩ to 92Ω but less than 100Ω for this particular sensors and any anything above it indicates a failure of the sensor. Module 2 (T2 is bad), Module 3 (T2 & T3 bad), module 4 (T3 is bad). Did you check this with a ...

Hello,

I have same issue with a G30 530e (SP06), i got this reading from Cell Module 2 checked at the connector at room temperature about 25 C,

Did someone here know if it is ...
