Mercedes EQV Electric Engine Errors

My 2023 Mercedes EQV electric engine is throwing errors It has 45416 km on the clock I seem to be getting an undervoltage detected error The van starts poorly some systems are failing intermittently and the lights are flickering sometimes The battery feels super weak when starting Could it just be a dead battery Or is it something more serious like the voltage regulator or some other electrical problem Any ideas

Undervoltage on an EQV points to potential issues A significant voltage drop can wreak havoc on the power supply Before assuming the worst have you checked the battery voltage with a multimeter What readings are you getting If it's consistently low a discharged or defective battery is highly probable I had similar electrical problem What error codes are showing up

Thanks for the quick response I don't have a multimeter What kind of error codes did you see when you had the issue And was it only the battery or something else

My EQV exhibited similar symptoms traced back to a faulty battery module causing an overall voltage drop Given your symptoms and lack of testing equipment coupled with the error I strongly advise a workshop visit Continuing to drive with undervoltage can damage other components They can properly diagnose the battery and related electrical issues Don't keep driving it without knowing what's going on

Just wanted to say thanks for the advice I took it to a workshop and you were spot on it was indeed a defective battery They replaced it and the undervoltage error is gone Cost me around 290€ but at least everything is working perfectly again I appreciate the help
