How to replace soft top motor without removing roof.. DONE!

Mike, thanks once again. I will have a look at that. I assume that it will be a time consuming process considering that I have to drain/refill the hydraulic reservoir every time I want to see the effect of an adjustment of the bolts.

Mike,

just took a look at it. Were you referring to the two bolts visible in this picture on the side of the metal block? From your first description it sounded like I had to take off the fluid reservoir...

Anyway, if these two bolts are adjustment screws then I'm screwed (pun!). They don't move at all; completely rusty. Trying to turn them only strips them :(

Do you know if the whole pump can actually be taken apart? It's so frustrating to have come so far and still have to buy a new unit for $500.

No, they are just blanks in a new pump. You need to remove the plastic reservoir from the top, they are in there.

Good afternoon,

I have been accompanying this forum for some time, which is very useful for me.
I live in Brazil, where convertibles are very rare and the workshops do not have the necessary knowledge to perform the repairs. Sorry for the grammatical errors (I used the google translator to write this post).
A few months ago the hood of my BMW Z4 did not work. At first I could hear the sound of the electric motor. Then even that noise stopped.
Yesterday I removed the rooftop and the electro-hydraulic motor, to which I verified that water had entered. I performed the kerosene bath, which caused the electric motor to run again. However, despite hearing the engine noise, the rooftop does not move, that is, it just unlocks.
I suppose there was a problem with the bypass system.
In order not to need to remove the hood again to service the engine, I cut the attachment point of the engine's plastic cover to one of the pillars of the hood. I removed the plastic part from the bowden cable attached to the motor, and saw that the supposed bypass button is fixed (it does not move out or inside the housing). I used v40 oil to try to unclog it, but it did not change anything.
I think the problem is the bypass release. What should I do to release the button?

Hey mike, my '08 z4 roof has stopped working, it unlatches/latches but doesn't go up or down. Any chance you could help? Thanks
