Skoda Rapid Idle and Check Engine Light Issues

I'm about to lose my mind with this Skoda Rapid from 2009! The gasoline engine is giving me fits. It has 212011 km on it, and lately, the check engine light keeps popping on. To make matters worse, it keeps stalling at idle. I'm suspecting it has something to do with a fuel tank ventilation system leak but I am not sure. Has anyone dealt with anything similar? Could a defective activated charcoal filter be the culprit behind these emission control problems and poor fuel efficiency?

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.

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!
