Peugeot 3008 Check Engine Light Air Valve
Summary of the thread
A 2018 Peugeot 3008 owner experienced a check engine light issue, suspecting a defective hose connection from the pump to the air valve. Symptoms included occasional engine stalling and rough idling, particularly when cold. Another owner suggested it might be a vacuum leak related to manifold pressure problems and recommended a workshop visit for a smoke test. The issue was confirmed to be the hose connection, which was resolved at a cost of 175€.

Yeah, there's been occasional engine stalling and some rough idling, especially when the engine is cold. Does that sound like your 'manifold pressure problems'?

Bingo! Vacuum leak somewhere, guaranteed. I bet it's the air valve like you suspected. I'd say save yourself the headache and take it to a workshop. They'll smoke test it and pinpoint the exact spot.

Took it to the shop, and you were right, it was the hose connection. Cost 175€. Thanks for the help!

Peugeot 3008 driver here! Check engine light, eh? Sounds familiar. Manifold pressure problems, maybe? Any engine stalling or idle problems along with it?
