ok for the time being i found a free transducer that seems like it works but is not exactly like mine i think is the replacement of the one i have in my car and fited to the car it hold 14 hg of vacum and it does retract the flap on the right side of the turbo parallel with the egr valve ( i cant see if egr is doing anything) so i know it works. how do i know that the egr is working etc. or better ask (since i could care less if egr is working or not) how do i know that the boost is working properly coming from EDS? plus i putt silicon around that vacuum control valve as that guy at the benz dealership said but i don;t know how much vacuum it should hold since i think its holding some now? also another question do you know of any procedures on how to align head lights since i switched mine to euro or a thread to point me to.

thank you
