I dismantled the wur with the intention of rebuilding it. I bought a repair kit for this purpose.
Porsche 2.0 924 turbo / 1980 / 170 CP / M31.01 / 93160610500 WUR part number / bosch 0438140062.

I discovered a large (third) spring in it, the first 2 are smaller in diameter. Initially I thought it should be removed - later I received enough arguments that it should be there.

The main question: Does it have to be the third spring in the wur or not?
The secondary (operational) question: Is the enriched mixture given by vacuum or boost?


I already have a formed point at this point - but I also call on your experience to clarify some aspects.
