Modus check engine light air valve issue
Summary of the thread
A 2010 Renault Modus owner is experiencing a recurring check engine light issue, suspected to be related to the air valve. The problem is thought to be caused by a defective hose connection between the pump and the valve. Another individual with a similar experience suggests checking vacuum hoses, particularly around the throttle body and air intake, as a vacuum leak could trigger the light. The issue was resolved by identifying and repairing a split hose, confirmed through a professional smoke test at a workshop.

Thanks for the quick reply! When you say vacuum hoses, are we talking about the small ones connected to the air supply? And how did you eventually solve the issue? Was it definitely a hose, and was it easy to spot?

Yep, those small hoses are the ones. In my case, it was a split hose that was hard to see at first. Honestly, I ended up taking it to a workshop. They diagnosed it pretty quickly with a smoke test. Probably best to get it checked professionally.

Okay, thanks a lot for the info! I took it to the workshop, and you were spot on. It was indeed a defective hose connection from the pump to the valve. Cost me 175€ to get it sorted. At least it's running smoothly now!

I had a similar problem with my Modus. Check all your vacuum hoses, especially around the throttle body and air intake. A vacuum leak can cause all sorts of weird engine behavior and trigger that light. It could be something simple like a cracked or loose hose.
