Just bought another vRS, it's thrown up fault code 17840 which google says is secondary air pump (air injection) all the pipes and secondary air pump seem to be new, but there is an unplugged plug under the vacuum assembly valve (is that was it is, at the front of the engine under the inlet) seems to just hang there, not sure if it has been unplugged for a reason, or if it is to do with the above code, anyone any ideas?!

 

Thanks

Any pictures?
