I presume that you are talking about priming it with oil to prevent dry running ? Would be surprised if the turbo would spin up when the engine was initially started anyway, but if it is a concern the easy way would be to drain some of the diesel from the fuel filter which will then require a bit of cranking before the engine catches. You can remove the diesel after taking the top off of the filter with one of those basting thingys that the wife uses on the xmas turkey ....... just make sure that it is clean!
Mine (w210 2001 vintage) is under the engine cover on the nearside, it is a joy to undo as not obvious, undo the large castellated ring being very careful of the plastic diesel lines (which can and will break easily) . I use a fabric oil filter tool which I still have to be careful with.
