Hello!
I have here Sprinter 209 MY2007 2.1 CDI EDC16CP31 0281014347 with EGR problem. I have disabled EGR and DTC but when EGR is connected I have blinking MIL and DTC P2511 when I disconnect EGR I have P2527. I have disable DTCs with switch on 18E44A and 18E44B but after that same thing MIL blinking and dtc present. I have found Manufacture code switch at 16585A and 16585B and 00 them. Now I don't have DTC on diagnostic but MIL still blinking.
Please someone have a look and help here.
Thanks in advance
P.S. DTC are exactly P2511-001 and P2527-004
