Espace engine stalling and idle problems

I've got a 2010 Renault Espace with a gasoline engine, and recently the check engine light's been illuminating intermittently. I've clocked 163450 km. Symptoms are pointing towards an air valve issue, potentially a defective hose connection from the pump to the valve. Could this be the culprit for engine stalling and idle problems, and if so, is it a simple fix or am I staring down the barrel of a full throttle body replacement?

Hey, I had a similar issue with my Espace, although yours is a good bit newer than mine. The symptoms you describe sound very familiar. Have you checked the air supply hoses for any cracks or leaks? Sometimes it's just a small split that's causing the issue.

Thanks for the quick reply! I did a visual inspection, but didn't spot anything obvious. Was your problem visible, or did you need to do a more thorough check to find it? Any specific areas I should be focusing on?

Mine wasn't immediately visible, needed a bit of wiggling and prodding to find it - the split was on the underside of the hose. Honestly, given the age and the symptoms, it's probably best to get it checked at a workshop. They'll have the right tools and diagnostics to pinpoint the issue precisely. Could save you a lot of time and frustration.

Appreciate the advice. Took it to the workshop, and you were spot on. Turns out it was a split in the hose as you suggested. Repair cost me 175€, including diagnostics and the replacement hose. Runs like a dream now. Thanks again!
