Hello to all. I have a problem with my w124 e300 year 1994.
After I replaced all the glowplugs the transmission start to shift very bad and roughly maybe I didn't connect in right way all the vacuum system. Please anybody can help me with this?
engine om606.910
gearbox 722.4

I found on the internet the schematics vacuum but I dont understand where are a, b, and c in my car..
I posted also a photo: i have brown/blue pipe and white(is the exact color white? because on the schematics I dont understand what is sw?) pipe but I havent the other like the green and the other white..

When you pulled the intake manifold off, there are two vacuum lines that attach to the actuators for the plenum flaps. You have to make sure those get back on there well or you will BANG every shift.
