Hi, I've got an oil leak (and some old berries a mouse decided to collect apparently) where a vacuum line attaches to the engine intake manifold, location in engine bay is front center. Any one knows how to fix this and / if it is a symptom of a component having failed?

Following the vacuum line away from the intake manifold, it connects into an electronically operated unit part number 002 540 18 97, which in turn via another vacuum line is connected to a second unit with part number A 112 141 00 69 .

It would be helpful to know what these are / do as well. On Google search they have all sorts of different designations.

Any ideas would be appreciated.

Does it leak oil when sitting still, or only when you have oil pressure?

I just went through this and made a DIY for it. I can't say that you're having the same issue, but hopefully this helps:

Very good job tracking that oil leak down.

My oil leak is between the valve covers right at where the vacuumline meets the intake / block.

Anyone else having suggestions or know of this issue from before?
