Seat Formentor hybrid engine issues

I had a similar issue with my Vauxhall Astra a few years back. The symptoms you describe sound very familiar. Rough running, engine stalling – classic signs. When was the last time you changed your spark plugs? A failing spark plug can cause a misfire, which would trigger the check engine light.

Spark plugs, huh? I've never changed those myself, to be honest. What's a misfire exactly? And could that really make the engine stall completely?

A misfire is when one or more of your engine's cylinders isn't firing properly. This can happen for a number of reasons, but a faulty ignition coil or a bad spark plug are common culprits. And yes, a misfire can absolutely cause stalling, especially at idle when the engine is under less load. Given your mileage and the symptoms, I'd strongly recommend getting it checked by a professional. It could be a simple fix, but it's best not to risk further damage.

Okay, so I took your advice and went to the local garage. Turns out it WAS a dodgy connection on the ignition coil! They sorted it out, new plug and everything, cost me about 95€. Engine's running smooth as butter now. Thanks a million for the help!
