roof pump noise. after replacing hoses roof latch, I hear ringing in pump, oil loses some hydraulic cylinders, I found oil under the rear seat, the squeak is air in system ... effort ¿.
I low fluid in the reservoir after several operations, when comes the shriek principalmete ... besides getting a little slow operation.

sorry tanngo, can't understand your question buddy.
The pump will make a noise when operating. Its normal. Running the top through several cycles should move all of the air from the system. It may take more than a few if there is alot of air. If you lose oil again, you've got more leaks, and air will continue to get in.

I have noticed over the past few months that the hood operation is getting louder. It is usually at the beginning of the cycle when the roof is being raised. It then happens again towards the end of the cycle when the roof is almost closed. It sounds like hydraulic action and it is very audible and getting worse.

While not directly addressing his full issue, one thing Tanngo mentions is the "ringing noise" when operating the pump. I too have this noise. I know it is air in the system. Whenever I close or open the roof, when the pump first starts, I hear air in the system for about the first second of operation. It clearly is air, yet seems to have zero affect on the operation of the roof. This has been happening for over a year ever since I replaced the latch hoses, yet, I can positively without question confirm that I have absoloutly no leaks anywhere. I marked where my fluid level was last year, I open and close the roof nearly every time I drive the car, and the fluid level has never dropped when I recheck the level. I also have pulled the rear seat recently for other reasons and inspected the rams, dry. The last time I pulled the latch cover to inspect things it was dry too. I presume that there still is air in the lines somewhere and for some reason never was purged. But it has not affected operation, so I just have left it.

Steve,
I have doubts about the 'self-purging' bit myself.
It is a closed system and while I can see the volume of fluid displaced by the lift rams would be enough eventually to purge air in their lines,
it seems surprising that, given small displacement of the latch cylinder together with the length of the lines (and hence large volume) would let this part of the system purge.
Gus, who knows a great deal about the hydraulics, says it does though.
