Hello!

I have had a sluggish 1.5 dci (2012) for quite a while now, cleaned EGR, replaced a vacuum solenoid and had it smoke tested, all with no results. The garage scanned it today and got the code:

2004 Intake Manifold Runner Control Stuck Open (bank 1)
2004 Intake Manifold Runner Runner Position Sensor/Switch circuit high (bank 2)

As he knows i like to do my own work he pulled a Mercedes intake manifold out to show me these flaps that control the air flow and explained it may be gunked up, "worst case you might need a new intake manifold as it comes as a unit".

Ive had a look on eBay and i cannot seem to find any intake manifolds at all for the 1.5 dCi Qashqai? Has anyone got a diagram of the location of this manifold? Is it called something else on this block?

Also, is it recommended to fit a new manifold or just clean out the old one? I don't believe this is a common fault.

Thanks!
