Hello,

I'd like to know whether the oil pressure on Mercedes cars is measured after the oil passes through the oil filter element, or before that? Thanks.

Until I study the flow diagram I won't be able to answer completely.
Bet somebody here knows the answer already.

But... It it were picked up after, you might think that filter quality would effect oil pressure.
Unless a filter bypass exists and then you would not see any change.

Using the in dash mercedes gauge I never have anything other than the full 3 bar at all times while driving.

Which my friends and I sort of chuckle at.

I think it must be after. I just put a new filter in and the gauge seems to take an extra second to ping up to 3 when I start the car. This would mean it measures it after the filter, right?

This is a bit of an old post, but it doesn't look like there was a definitive answer and I was looking at the diagram for my '83 300Dturbo last night -- on mine, the gauge measures pressure, after the filter media, of the oil that goes for lubrication. So.. the more the merrier (unless your more is because of clogged nozzels).
