D208 - can massage engine control unit faulty

I cheked :
1 - engine ecu - but in ecu are 0 faulty codes .
2 - cheked near battery wiring - ok.
3 - Cheked BSI wiring - ok
4 - Cheked ABS/ESP plug and wiring - ok.
5 - Tested Can comunication 120omh - ok
6 - Cheked egr plug wiring - ok

Maybe some one know were could be a problem? I add readed ecu dump ,maybe this file changed or no original.
