Thanks it was very helpful, to me the headest part was taking the center vacuum pod in the airbox, there is a robber door on the driver side but you need small hands
I also fund on the floor little rubber squares where these come from?

Questions: my car is a 92 300D, and on the passenger side under the vent there is a motor connected to a house, what is that for?
Also in the driver side near the vacuum pod there is a Black vacuum line not connected to anything is that normal ?

to bad I can't upload any pictures I guess you need a spacial account ?
