My Star W204 C220CDI OM646 C220CDI (Delphi injection) was diagnosed by a mechanical friend of mine who has the Mercedes DAS Xentry Diagnostic Software and, according to him, had a high value injector and it was better to replace it !! I bought a new Delphi injector from a UK website, it was replaced and coded in the Xentry program with the new 20-digit code, it turns out that the Injection Correction (Zero Quantity Correction) value has not changed from the old injector to the new one !!
Values at idling speed:
Cylinder 1: - 19us [-68...68] Cylinder 2: 66 us [-68...68] - - > this is the one that was replaced but the value didn't changed!!! Cylinder 3: - 23 us [-68...68] Cylinder 4: - 24 us [-68...68]
Does anyone know how to "interpret" Xentry's "Zero volume calibration for X cylinder" values?
