Hello, I have a VW Passat [Estate] from 2006 and I’ve recently been having issues with it. A light appears on the dashboard. I went to a Mechanic and he tested it. The computer found a fault, code: 012600 P3138-006 Intake manifold Runner Control : Regulation Deviation. I changed the valve, the light on the dashboard no longer appears but I can still hear a noise in the engine when I accelerate.
