Skoda Superb Hybrid Starting Problem

I am experiencing starting difficulties with my 2021 Skoda Superb Hybrid. Mileage is 65409 km. The engine turns over poorly. I suspect a Terminal 30 continuous plus interruption. Could this be a heavily discharged or defective battery?

I had a similar issue with my Superb. Check the Voltage Drop when starting. Could be the Starter Motor drawing too much current. Also, inspect the Wiring Harness for any corrosion or damage. The Power Supply to the Starter Motor could be the culprit. Have you checked the battery?

Could you elaborate on how you checked the Voltage Drop? What is a normal reading?

I used a multimeter to measure the Voltage at the Starter Motor while cranking. A significant drop below 10V indicates a problem. If you're not comfortable doing this yourself, I would recommend a workshop checks for Electrical Fault. In my case, it was indeed a faulty battery causing excessive drain.

Thank you for the advice. The workshop confirmed it was a defective battery. Replacement cost was 290€, and the starting issue is resolved.
