    Hi,

    I am new on this forum.

    For some time, the opening and closing of the roof became slow.
    It even needs some manual assistance to close it.
    It seems that the hydraulic system is leaking.
    Has anyone already faced this problem? What was the solution?
    Thanks in advance for your suggestions.

    By the way, I live in Singapore. If someone could recommand me a good workshop where this issue could be fixed, I would appreciate.

    Regards.

    Del.

    Hi Del,
    Welcome to Copenworld.
    It's not a problem I've heard of before.
    I would suggest going to a Lexus or Toyota dealer to investigate the problem.

    Hi Del,

    you might want to try Kan Fook Sing Motor, understand they do service a number of copens here in sg. Try google for address and check with them your problem. Do feedback if it helps.

    Hello Del,
    You say the system is leaking. Have you found the leak? Is the hydraulic fluid level low?

    You can see the operating cylinders if you remove the large plastic covers behind the seat. Have a look at THIS thread for a photo 9th photo down. Cylinder on right hand side of photo. Silver with black tape across the middle)

    If the fluid level is not low, some other ideas are:
    1) cylinders loose - check fixing
    2) the roof is very stiff. Try to operate it manually - see manual for details.
    3) the pump has a problem (located under the pull up cover in the boot).
    4) one of the the cylinders has a problem with the seals and is passing fluid.

    Good luck.
    Rex.

    Thanks to all of you for your comments.

    It seems that some cylindres are passing fluid (they are greasy) and there is no more liquid in the pump (or at least no more in the transparent reservoir).

    1°) Rex, you mentionned in your post that I could operate the roof manually. How can I do this? I do not have any manual to help me.

    2°) How can I refill the pump, and which kind of fluid can I use?

    Thanks in advance.

    Del.

    Hi Del,
    In the owners manual, it describes how the roof can be raised & lowered manually.
    If you haven't got one look in the directory tab at the top of the forum.
    You can view a manual for a 1.3 Copen. The roof operation is identical.
    You can also download the service manual. Within that you should be able to read about the hydraulic roof system (section I5) & will tell you which fluid to use.

    Thanks Adam,

    But I went through the I5 section of the service manual and I did not find any information about the fluid to put in the roof hydraulic pump system.

    Can anyone help?

    Thanks in advance.

    Del.

    Your right, I've just been through that section & tried some of the information sections. I couldn't find anything that specified the hydraulic roof oil type.

    I would contact a Daihatsu dealer & ask them for some hydraulic roof oil. See how much it costs. At least you'll know it's the right stuff.

    However I have done a quick google search & came up with this.

    Thanks.

    I tried to diagnose the pb yesterday.

    What I found is:

    1°) It seems that there is not enough fluid in the pump. You can refer to the enclosed picture. I have put a red line to show the fluid level. Is this the same on your cars? There could be some air in the system.

    2°) When I open the roof automatically and I stop the process in the middle, the roof slowly goes down. Same question: is this the same on your car?

    I am a little bit sceptical about Daihatsu Singapore: I did a first approach and they answered that the whole system had to be changed (pump + cylindres ...) for 13,000 SGD ! ! ! !

    Thanks for your comments.

    Del.

    yes
    Point 2 is definitely showing a problem! The roof should stop anywhere in the middle and stay there.

    Hi Del,
    Just checked the fluid level in my car. It's only slightly higher than yours. Just over halfway.
    My roof doesn't slowly go back down again when stopped halfway though.
    Maybe your getting let by on a seal in the system that looses the pressure.

    Oooh this is my 1000's post! Yeah me!

    Del,
    It must be a seal gone either in a cylinder or the valve block by the pump.
    Problem is I can't think of an easy way to find out which. Really need to block off the cylinder return pipe and see if the roof still moves, but how???

    Rex.
