Help for peugeot Ion 2012 that doesn't work.

update: The can-bridge works,
I filtered the voltage value of cell 6 (can id: 613) by taking that of cell 5 and was able to move the car. Last week I managed to take it for inspection and then gone to home, covering about 15 km. The car stopped often and sometimes even went into turtle mode, but little by little I reached the destination.
Monitoring the data collected with Carscanner, I saw that cells 4 and 8 also give values of 2.1V. I tried to filter these too using an algorithm that does not completely ignore their value, but I noticed that with the increase in seasonal temperature everything got significantly worse.
In the meantime, I ordered the CMU #1 board and it should arrive today. This morning I did an analysis of the data collected during the trip and I noticed something "reassuring" which is that only the voltage values of CMU #1 are incorrect, the less "reassuring" thing is that I also found some temperature values that have peaks at 200 degrees Celsius, in cell 8 (but here I will replace the card) but also in cell 12 which would be under card #2. All other temp and voltage values seems ok.
Can these temperature spikes cause problems?

Intermittent, high temperature readings are another known CMU fault, they are not real but the BMU doesn’t know that and may limit power (tortoise) as a result.

If this happens on CMU 2, best to replace it also, in the meantime the CAN bridge can take care of this temporarily

Thanks @MickeyS70 . I only ordered #1, can I manage to repair board #2 in your opinion? Is there a diagram of the temperature reading part?
