Battery Warning Light and Non Start
Hey guys.I drive a W204 CGI. A red battery warning light appeared on the cluster and after a few kilometers the car stepped running.
Took it in to a workshop and I was requested to get a battery sensor. I got the sensor installed and charged my battery at a battery centre.
The car does the same thing. And won't start again.
What am I missing? I was told the pyrofuse might have something to do with it. Help 🙏

It sounds like your charging system is not working. Recharge your battery then test the voltage at the battery with the engine running. It should be above 14 volts. If it's less than 12.8 volts then the alternator is not charging the battery (and the red battery symbol pops up on the instrument cluster).
