DS4 Intake Air Temperature Sensor Issue

Thanks for the tip! The reading seems off, that's for sure. It's showing really high even when the engine's cold. Did you end up replacing the IAT sensor yourself, or did you take it to a shop?

Given the symptoms you're describing, it does sound like a faulty IAT sensor. I'd strongly advise consulting with a qualified technician for a comprehensive diagnostics and repair. In my case, the error stored in the error memory indicated a defective IAT sensor, so they replaced it with a new one.

Cheers! I took it to a workshop and it was indeed the intake air temperature sensor. Replaced it, and now it runs perfectly again. The total repair cost was 155€ Thanks for the help!

Interesting! I have a Citroen DS4 too, and something similar happened to mine a while back. Check engine light, rough idle – the whole shebang. I'd start by checking the temperature reading from the air sensor with a scan tool. What kind of values are you seeing?
