I did that job on my 2006 3.0si when first purchased, took about 5 hours and parts were @ $350 back in 2012. |

Your photos (excellent) helped me so much. I figured there where 3 stainless pins, but only one was found when disassembling the pump. I figured it was useless to look around my work area for those other 2 pins. As I was fumbling around, I noticed that the motor had a strong magnetic pull. I went to my original motor (tucked away in a zip lock baggie) and WOW!!! the missing 2 pins were attached to the motor down in one of the recessed areas. I put it all back together (for the 3rd time) with all of the pins. Nothing... so, I read further into your post(s) and there it was - the "brass nipple" issue. I decided to disassemble the entire pump and I found a lot of internal parts that had become immovable over time. Sprayed it down with carb cleaner, then reassembled the pump. Put all back together again, put in fresh hydraulic fluid (again) and assembled the entire unit. And... IT WORKED!! A big thank you (I know its like several years later but I am so thankful) for solving my Z4 convertible top issue. |

I have just done this job this weekend without roof removal. It is not overly super hard but I am smaller guy so it was a little easier 😂. Someone tried to fix it beforehand because zip ties were already cut and it literally took me about 30 mins to get the pump out. My motor where it seals with the pump was missing about 3/4 inch piece so all the fluid leaked out. I have replaced motor with new o-ring and refilled missing fluid with CHF 202 by Pentosin This however wouldn't make it working. I had to remove plastic that is sitting at the hydraulic pump that fits over bypass valve for manual operation. I've used some fluid to dissolve corrosion from the pin. If the pin is stuck it will not allow for the fluid to enter hydraulic lines. Once I've successfully freed it up conv. Too started moving but not all the way. It took 3-4 fillups to make it working and sound right. I have of course relocated pump with motor into the trunk. Now I have working top back again 👍
