Good day to everyone. I bought an Audi 100 2.8 AAH EZ:12.1991 with Tantarini LPG system last week. The following is what I have to do: The subject of the switch suction tube, I had an Audi 80 with AAH before and the switch suction tube turned off wonderfully. With the new switch it doesn’t at all. I looked at the cables and noticed the following The previous owner installed a cold running regulator and as it looks like he connected it wrong. Low pressure can from the SSR and from the throttle valve (small hole) a line goes to a T-piece and from there to the cold running regulator (bottom). And from the cold running regulator above a line goes to the engine block for the temperature sensing. Picture 1 I once drew THAT IS still FALSE So the SSR can’t switch. OR ??? I found the solenoid switch valve located below the LMM and there is also a cable connected blue and goes over to the????? I tried to unscrew the suction mount with the two 10 screws and tried to push it backwards to make it off but unfortunately I can’t. With my Audi 80 AAH it had enough bursts to the rear but with the Audi 100 I didn’t have a seat in the rear. I want to buy and connect new cables now. (what kind of a hose do I need?) Just how do I close it I found an ETKA picture and drew red and blue (picture 2) IS THAT RIGHT Do I have to pay attention to something else? Could it also be that the switching suction tube has somehow stuck because it certainly hasn’t switched for a few years. Should I somehow fix it or? As it is connected now it also pulls somehow wrong air that the car now has a bad idle it stutters in status. Thank you already in advance
