I warmly welcome. I have a problem with the vacuum bulb in the passat b5 1.8 engine ADR. After many attempts to connect the vacuum hoses, unfortunately the car still works poorly. No acceleration, no elasticity, problem with setting lpg. I ordered a few others but either they came from another engine most probably 1.6 does not fit the bolt spacing and the whole element is a little bigger than mine or I got a kind of good part while after connecting and resetting errors the problem still remained, disassembling the part turned out that the plastic element connected to the membrane is damaged eg through a hole or simply the rod does not work as it should. It is very hard to find this element in general, and what is it that works. Apparently there is some way to connect the vacuum hoses, bypassing the pellet vacuum. If someone can help with a detailed description, diagram or the best picture, I am asking for help and putting a big beer. I am struggling with this topic for half a year. At the moment, a damaged pear is mounted without this agent that opens and closes.
