W203 SW 220 CDI No Power , no bad smoke , car doesnt overcome 3000 rpm.
 

Hi everbody, im workin on this C220 CDI 2004. My client told me that he had replace the EGR valve and the Mass air flow and the car still has no power. I connect Star Diagnosis. I tried it that the voltage on the rail sensor was 4.9V. Is any possibility that is the sensor fault or something else?
