All in all, the task was pretty easy and minimal tools were required.

So far, I replaced:
Conductor Plate
Pressure Spring
Sonnax Overhaul Valve Kit (all 3 Valves)
And Swapped 4-5 Solenoids with 2-3


The big plastic caps that i have missing on the conductor plate are to keep the metal shavings away from the solenoid contact points.
Waiting for the Magnet, Conductor Plate Covers (Thanks Gilly)

In my search for solenoids, i acquired 10 solenoids from a W210 (different part number from what i have) So if anyone wants them i can sell them at 20$ a piece. I'll get the part number if someone is interested.
