DQ200 Mechatronics diagnose & repair due to P17BF error. [Volkswagen Jetta MK6]

Initial diagnosis was P17BF - (Loss of pressure - To explain this in detail, the accumulator inside the mechatronic unit does the job of imitating a human pressing down the clutch. When this part can’t do its job, shifts either become jerky / does not shift at all. Imagine yourself half clutching / not pressing the clutch at all) Usually, what happens is, the housing in which this accumulator is screwed into, breaks causing an inability to maintain the target pressure, but in my case, the o-ring in between the accumulator and housing disintegrated. I couldn’t find a crack in the housing. Nevertheless, I have already ordered a new valve body plate which is thicker than the one I currently have so I replaced it.

If you’re going to do this yourself, please be careful. Some components are fragile, some are easy to miss. Write down a list of to-do / checklist when you’re disassembling / reassembling the mechatronic unit. Watch a few different RUclips videos first to get an idea of what to do. I usually look for videos with the same engine cover as mine, so I know for sure that everything done in the video, matches mine. I will try to make a thorough video of a repair next time, highlighting every bolt / o-ring / gasket that needs to be replaced. Thanks for watching!
