Trajet check engine light air valve hose

Hey there! I also drive a Trajet, and your problem sounds familiar. My car started acting up similarly. The check engine light was on constantly, and it turned out to be related to the air intake system. Have you checked the vacuum hoses for any cracks or disconnections? That was the culprit in my case. It’s a pretty easy check you can do yourself, might save you some money!

When you mention checking the vacuum hoses, could you elaborate on the exact location I should be inspecting? Also, were there any other symptoms you experienced besides the check engine light, such as engine stalling or rough idling? I want to be thorough in my investigation before considering a visit to the mechanic.

Alright, so, I'm no expert, but I remember it was mostly around the throttle body area where the air valve is. Give those hoses a good look and feel for any splits. And yes, I also had some rough idling at times, almost like the engine wanted to stall when I stopped at lights. If you're seeing that too, it really sounds like a vacuum leak. Honestly, though, if you're not super confident, it might be worth a quick trip to a workshop. They'll pinpoint it fast, and peace of mind is worth something, right?

I took it to my local workshop, and they confirmed it was indeed a defective hose connection from the pump to the valve. The total repair cost came to 175€. I'm grateful for your insights, which helped me narrow down the issue and avoid unnecessary expenses.
