The 230e,240d,300d 123 5 speed 717.4xx uses a w201 part number 2012900311 slave cylinder. It is the same slave cylinder for the 717.411 that I have from a 190e. The 4 speed slave cylinders are different, although they will work. I don't think it is proper, as they have different push rod lengths
I can tell the system is the same. I'm 100% sure
The manual transmission 280e has different clutch parts than the rest. The hydraulic system is still the same, just different dimensions for the parts. This is a bit off subject but it ties in somehow.
