2511-001 Check component Y27/9 (left EGR positioner). Positioner signals fault.

Does it mean the egr is knackered or needs a clean?
Thanks
 
Yes.... The egr valve was completely blocked and the actuator lever couldn't move.
I cleaned it a few times , However I think the electric motor was weak... So I replaced
Did you get this resolved?
it with a working 2nd hand one and all is fine for now.
