307 2.0 motor codigo p2006 - 2007 Peugeot 307 1.6

Its part of the intake manifold. I am guessing here but may be a broken clip or stuck linkage. Check youtube or search p2006 for free online videos and may show you what could be an easy fix or changing parts

It is an intake manifold valve that regulates intake airflow that is not working. Here is a forum that will help you. https://mbworld.org/forums/e-class-w211/601604-p2006-intake-manifold.html

P2006 = Intake manifold runner control stuck closed, Bank 1.
There is a set of 'choke' valves built into the intake manifold on the vehicle.
They are sticking closed, affecting the fuel to air mixture getting to the engine. The switches/solenoids may have failed so the will need to be tested or replaced.

Hope this helps
