Had a 2009 2.2 Sprinter 313 in on Monday this week with none start when cold, but started with a light sniff and run perfectly. Tested Delphi Injectors No 1 and 4 excessive leak off. Smooth running Cyl 1 -86 and Cyl 4 -73

Part numbers EMBR00002D £300 each won't fit recons advised customer to fit all four but because of cost he opted for the two.

Fitted and coded the two and faults now changed to Cylinder two and three and running like a dog.

Eventually after wasting half a day we fitted the other two injectors and all is now OK.

In my opinion these Delphi injectors should be fitted as a complete set, otherwise your asking for trouble. The only good thing about them is they were not seized in the head.
