Skoda Karoq rough running and stalling

Rough engine running and stalling at idle, combined with the check engine light and jerking, strongly suggests a misfire. Given the mileage, a coil failure is quite plausible. Before condemning the coil itself, meticulously inspect the wiring and connectors leading to each coil pack. A loose or corroded connection can mimic a faulty coil. A multimeter can be useful to test the coil's primary and secondary resistance, comparing it to a known good coil if possible. Have you performed any vehicle diagnostics to pinpoint which cylinder is misfiring? Knowing the specific cylinder will allow you to focus your attention on the corresponding coil and its associated wiring.

Thanks for the quick reply. I haven't had a chance to do any in-depth vehicle diagnostics yet. When you mention testing the coil's resistance, what values should I be looking for, and where exactly on the coil do I need to place the multimeter probes?

Alright, without proper vehicle diagnostics confirming the misfire cylinder, you're essentially troubleshooting blind. While resistance values vary between coil manufacturers, any significant deviation between coils on the same engine indicates a problem. As for probe placement, you'd typically measure primary resistance across the two smaller terminals on the coil connector, and secondary resistance between one of those terminals and the spark plug contact. That being said, given the symptoms and your initial suspicion, it's highly likely a coil pack is failing. I would advise taking your Karoq to a workshop.

Yep, you were spot on. Ended up being a defective ignition coil. The cable and plug looked fine, so just replaced the coil pack. Cost me 95€, all in. Runs like new now. Thanks for the help!
