Oil leak at vacuum line front of engine?
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.
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:

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?
