Hi I'm a new member from Shediac NB Canada

I just purchased a 2004 BMW Z4 2.5 convertible.

I have a question about convertible top repairs.

I removed the power convertible top. It would not raise or lower. The top would unlatch from the top of the windshield and the windows partially lower etc. but nothing else happens.

I suspected after some research on this site that my motor/pump assembly was no good.

I ordered a new one online. I removed the top. I was surprised to find that the original motor looked as good as the new one except it was empty of oil. Maybe the hydraulic lines are empty too. I don't know

I found oil that appeared to be leaking from the hydraulic hinge? I'm not sure of the name, but the part that looks like a shock absorber or a jack that actually raises the top's frame when the pump/slash motor applies hydraulic pressure.

The part is on the left (drivers) side, the similar but opposite side part, is rusted as it was sitting in water but it doesn't appear to be leaking.

I haven't been able to find these parts on any online site. The left side has a number on it, PR365-A1131000 The right side is numbered PR365-A1130240

Anyone have any idea what the proper name is for these parts and where to find them. I figure it would be smart to replace both while the top is off.

Also if the lines have been drained of oil is there a fix?

Thanks:eek:

Check out Top Hydraulics in Oregon. They will rebuild (and upgrade) both for around $700. I've not found any other company that does this work.

Your part number

HELLO Schediac the part you are looking for is number 54347193449 it is the Left hydraulic hinge I have the same problem I will try to fix by myself.

After buying anything be sure that the leak is going out form the top of the hinge and not from any hydraulic line and unfortunately you bought a new motor when you should check the cause of your problem , sorry.
