P0410 Again !!
Hi guys, i'm sure this has been covered before but i keep getting the engine light on despite a new air pump fitted and replacement changeover valve but my question is, does anyone have a diagram of exactly how and where the change over valve plumbs into as I think maybe I have a hose missing or have missed a connection somewhere. I have trawled the net but can find no diagrams. The car is a W204 C63 M156 engine and i just need a clear picture of where everything goes.
On the change over valve there are 2 stems a thicker one and a thinner one. Which stem is the vacuum to the maniford? thick or thin? I know one of the stems is the vacuum to the check valves I just think I may have them round the wrong way

Thank you ever so much for those pics, they have helped me greatly. I did pop out again at lunchtime and have a little look again and i wiggled the big pipe that runs from the secondary air pump to the check valves and the CEL went out so I am thinking there may be a split in that pipe. I will remove it at the weekend to inspect but thanks again for your help
