Hello, as the title says, one of you has already changed the vacuum box with 163hp in the model? According to various sources there were contradictory statements turbo center and repairer where I had bought turbo and sent back read the negative pressure box three screws on the attachment and “securing” on the Vertseller VTG etfernen, hook out and install new can.No adjustment, probably goes automatically ? A workshop and an experienced screwdriver as well as si and the opinion of the models C4 and C5 with 128hp I believe until 2008 will be set with sheets / plates. Lt. Citroen no documents for setting is also not provided, whole turbochargers exchange. Sure! Whole problem is that the poti/receiver always gives 100% signal position as feedback to MSG. Water entry, /electronics defective. Pneumatic part is dense and only the sensor data works far apart(clear if always 100% are reported) and the car is up to 200 revolutions lame and sometimes dropouts. MSG can no longer rule it out. I would be very grateful for constructive help. VG from the Ruhrpott
