Hello everybody,
Does anybody know where is the SOS eCall module on the Leon MK4?

I would like to check if the battery is faulty or if the module needs to be replaced.

Besides, does the SOS eCall work with Cubic Telecom data? I'm asking this because my data plan with Cubic Telecom has expired...

Thanks a lot!

Behind the instrument cluster, if I'm not mistaken. It is generally called telematics unit or OCU.
