2009 Sprinter smoke and fuel in oil

[Centraltt]

Hi. I have a 2009 sprinter 515 that occasionally smokes (white smoke) it also sufferers from increasing oil levels (it maybe diesel in the oil). I have had the vehicle on the star computer and no faults registered. MB technician has also looked at it and can't find the fault. Any suggestions would be appreciated

could be low compression on one cylinder due to damaged piston rings, a compression test would help pinpoint low compression or faulty cylinder

Injectors that are faulty can have a bad spray pattern which prevents proper burning of the fuel. This will give you the symptoms you have.
