Peugeot 308 Hybrid Stalling Issue

Hey, I've got a 2022 Peugeot 308 hybrid and I'm running into some trouble. The check engine light comes on and the error memory says something about idle air control. The engine stalls at idle sometimes. Anyone seen this before? Mileage is at 62780 km currently. Thinking maybe it's the IAC valve but not sure where to start.

Sounds familiar. I had a similar issue with my 308, although it's not a hybrid. Stalling, check engine light, the whole nine yards. Have you checked the throttle body for gunk? A heavily contaminated intake can cause those symptoms.

Yeah, I was leaning toward the IAC valve, but you're right, the throttle body could be the culprit. Was your error code specifically pointing to the IAC valve or something more general?

Honestly, I can't recall the exact code, but it was definitely related to the air intake system and engine idle. Given your hybrid engine, I'd be hesitant to start tearing things apart myself. Might be worth a trip to a workshop, just to be sure. Those hybrid systems can be a bit tricky.

Appreciate the advice! Turns out you were spot on. Took it to a shop, and they said the intake was heavily contaminated, causing the IAC valve to malfunction. Cost me 425€ to get it cleaned and the valve sorted. Runs like new now!
