hi folks first time on and probably not the last unfortunatley.Have had a few problems but will keep it to the fault code that i got.Twice the car has lost power and both times when put on diagnostics it has came up p2511 and 2511-1 check the component y27/9 (LEFT EGR/ARF POSITIONER) Positioner signals fault.Hoping for some info as changing the egr valve is expensive(dont mind the cost as long as it cures problem)and not alwasy guaranteed results.The car is a clk w209 220 cdi.Sorry meant to say i have already taken the valve out and cleaned it up(wasnt the worst i have seen)Thanks in advance.
