Om626

[Gibbi]

Hi everyone. Has anyone got a diagram of the intercooler o ring gasket order on my w205. Thr egr valve was replaced a few months ago by an independent Merc garage & since then, oil mist has appeared on the heat shield under the hood. I’m presuming they have not fitted the seals correctly. The car has only dome 14000 miles. I cant seem to find any info for the Renault built om626 engine showing this. Many thanks all.
