Skoda Rapid Idle and Check Engine Light Issues
Summary of the thread
A 2009 Skoda Rapid with 212,011 km is experiencing issues with the check engine light and stalling at idle. The problem is suspected to be related to a fuel tank ventilation system leak, possibly involving a defective activated charcoal filter. After replacing the charcoal filter, the check engine light issue was resolved, and the car idles properly again.

EVAP system pressure sensor? Where exactly is that located, and is there any way to test it without special equipment?

The sensor is usually near the fuel tank. Honestly, without proper tools, it's hard to diagnose it definitively. Considering the symptoms and your suspicion of the charcoal filter, it might be best to get it checked by a workshop. They can properly diagnose the EVAP system.

It was the charcoal filter. Replaced it, and the check engine light is gone, and it idles perfectly now. Cost me 275€ all in. Thanks for the help!

Sounds familiar. I had a similar issue with my Skoda Octavia. The check engine light and rough idle are classic symptoms. Have you checked the EVAP system? Could be a faulty pressure sensor causing issues with the air flow.
