Skoda Karoq Diesel Terminal 15 Ignition Problem

Whoa, that sounds rough! I had something similar happen in my Karoq, though it wasn't exactly the same. The power supply went bonkers. Have you checked the battery terminal connections? A loose connection there can cause all sorts of weirdness. It's like when you have a loose light bulb – it flickers and maybe doesn't work at all!

Interesting. When you say 'power supply went bonkers,' was the error memory also indicating a Terminal 15 interruption? And did you experience a voltage drop before the engine failed to start?

Okay, the error code wasn't precisely the same, but the symptoms were comparable: engine wouldn't start. I didn't measure the voltage drop myself, I'm not that skilled, but the workshop confirmed it was related to the voltage. They found the defective connection and said it could have been a short circuit waiting to happen. Honestly, I'd recommend getting it checked by someone who knows their stuff. It's better to be safe than sorry when it comes to electrical issues.

Appreciate the insight. I took it to a shop. Turns out it was indeed a defective cable connection. They located the circuit break, repaired the connection, and the error is gone. Total cost was 95€. Thanks again.
