Thanks. Can you elaborate on the air intake contamination? Was the IAC valve also affected in your case?

Confirmed – the intake was the issue for me. The contamination caused the IAC valve to malfunction. I recommend a workshop visit.

Much appreciated. Diagnosis confirmed a heavily contaminated intake, leading to a faulty IAC valve. Repair cost was 425€ Thank you for pointing me in the right direction.

I had similar symptoms on my Noah. Check the air intake – could be heavily contaminated. Is your throttle body clean?
