I already name them, so sure 100% no mismacth.

just be careful with the installation. Once the system detects you have opened the HV battery, the contactor will be opened and this will most likely require EOS tester to close the contactor. Ohh, To start, I open the HV connector at the boot in order to work on HV (got message on cluster that HV ...

Great. WIll order same. Do i need some sort of calibration after this fix?

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 indiv...

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...

Cell 3 Checked at the connector Temp Sensor 1 87 K ohm (Pin 2 - 18) Temp Sensor 2 125 K ohm* (Pin 9 - 25) Temp Sensor 3 210 K ohm (Pin 1 - 17) Cell 4 Checked at the connector Temp Sensor 1 88 K ohm (Pin 2 - 18) Temp Sensor 2 85 K ohm* (Pin 9 - 25) Temp Sensor 3 104 K ohm (Pin 1 - 17) Cell 5 Checked ...

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, Temp Sensor 1 90.8 K ohm (Pin 2 - 18) Temp Sensor 2 1.2 M ohm (Pin 9 - 25) Temp Sensor 3 91.6 K ohm (Pin 1 - 17) Did someone here know if it is possible to ...
