Skoda Citigo Low Voltage Diagnosis

My 2012 Skoda Citigo with a gasoline engine is showing signs of undervoltage. Symptoms include poor starting, system failures, flickering lights, and a weak battery. I suspect the battery is heavily discharged or defective, impacting power supply. Could this also be an alternator issue or a charging system problem?

Low voltage on a 2012 Citigo? First, check the battery terminals for corrosion and ensure they're tight. A loose connection can cause a voltage drop. Have you tested the battery's voltage when the engine is off? It should be around 12.6V. Also, what's the voltage when the engine is running? It should be higher, around 14V, indicating the charging system is working.

Good points. Where exactly should I measure the voltage when the engine is running? Directly at the battery terminals, or is there a better spot?

Yes, measure directly at the battery terminals while the engine is running. If it's not around 14V, you likely have an alternator issue. Given the symptoms and mileage, it might be best to have the charging system professionally checked to rule out any low voltage causes.

Replaced the battery and the voltage is now stable. The total cost was 290€. Thanks for the advice.
