Skoda Kamiq Engine Troubles
Summary of the thread
A 2021 Skoda Kamiq with under 40,000 km is experiencing engine troubles, including a check engine light, rough running, stalling at idle, and jerking during acceleration. The suspected cause is a faulty fuel pressure sensor or a bad connection. After checking the wiring and connections, it was confirmed that a loose and corroded connection on the fuel pressure sensor was the issue. Repairing the connection resolved the problem, restoring the vehicle's performance.

Interesting! When you say 'wiring and connections,' what exactly am I looking for? I'm not super techy, but I can usually spot something obviously broken or disconnected. Any specific areas I should focus on around the fuel injector or pressure sensor?

Right, when I had the issue with my Renault, the mechanic showed me that the plug connecting to the fuel pressure sensor was a bit loose and the wires going into the plug were corroded. Check if the connector is properly seated and look for any green gunk or frayed wires. A multimeter might help diagnose if the sensor is getting power, but honestly, if you're not comfortable with that, it might be best to take it to a workshop. They can properly diagnose and replace the sensor if needed. Ignoring it could damage the fuel injector or other components.

You were spot on! Took it to the workshop, and it turned out to be a dodgy connection on the fuel pressure sensor. New connector and a bit of wiring tidying, and it's running like a dream. 95€ all in. Thanks a million for your help!

Sounds like a classic fuel delivery issue. The check engine light plus rough running and stalling definitely points that way. I had a similar problem with my old Renault Megane – turned out to be the fuel pressure sensor as well. Have you checked the wiring and connections to the fuel injector and the pressure sensor itself? Sometimes it's just a loose or corroded plug.
