Please help with my roof!!!!

[mariocaz]

Hi guys,

I am new in the forum, I am from Mexico and I was very happy today because I just bought my Z4 E85 2007.

Saturday I checked very well the car and opened and closed the roof of course and the Z4 did it very well.

But today I came to home after the buy and open the roof a little in the way, have it like 10 mins opened, then closed and all well, but when I want to open it again only moves a little to open (with the open button) but then nothing, then I closed but go to close then a little open (this with the close button) and the red led stay flashing, then I leave the car off like one hour then again I want to open and the same only moves a little and nothing else and the red led flash again, seems like stucked.

So I looked how to open manually to see if something is not letting to open the roof, I put the roof completely down and now I cant close it, also I cant manually only I can move it very little and is very strong to close, so I dont want to do a damage or something.

I hear the motor(s) when I press the open/close roof button.

I am very sad, because I was really very happy to have my Z4 now with me, but now I am very worried, please help. (So sorry for my bad english)

This is my new baby......

Hi mariocaz and welcome to the forum!
The e85 Z4s are prone to suffer from roof motor failure caused by blocked roof drains: Use the search function (e.g. ”roof drain”, ”motor relocation”) and you will find numerous threads with lots of useful information. If you are lucky it might just be the red handle in the boot is stuck; then the motor running the hydraulic pump still runs but the bypass valve (operated via the red handle) is open. Worst scenario would be a hydraulic line leakage which is, fortunately, quite rare.

Welcome to the forum, nice colour. Is that a wrap or paint?

As above the E85 has a history of failed roof motors due to them drowning in there own little housing. This does sound like a dead/ dying roof motor from what you describe.

Most can be removed renovated and then refitted in a better position in the boot, without too much trouble or expense. Depends if you can find someone in Mexico to do the work. There are DIY help threads here if you are handy and up to fixing it yourself.

This thread has some links you should find helpful. https://z4-forum.com/forum/viewtopic.php?f=3&t=113283&p=1633901&hilit=roof+motor+replacement+E85#p1633901

A BMW dealer will likely charge you several hundred US dollars plus, for the work, so lets hope you do not have to go that route.

If you can't move the roof manually even with the red tab pulled in the boot then the bypass plunger on the pump is probably jammed. Either way, you almost certainly need to get the pump out for a clean-up / refurbish.

I fixed the problem sometime ago with a friend and his scanner......

he did this to fix my problem, he totally closed the roof manually, then he disconected the battery and completly opened manually, then he connected the battery and scanned the car, he found one code and deleted it and then uuaaalaaaaa hehehe my roof worked again.

Then after a while of not using the roof because I bought the hard top and I love it, so I took off the hard top to use the roof some days but I couln´t use it because when I wanted to close the roof nothing happened only I can hear a little the motor of the roof working but that is all.

I scanned the car and showed these errors......



Hope someone could help me.

Mine wouldn’t close one day. Long story short: I had a broken wire in the harness that runs from the pump to the headline of the convertible top. It was where the roof folded back on itself. It is somewhat common. The wiring harness costs a small fortune. If you remove the screws that hold in inner liner for the convertible top, you’ll be able to get to the harness. You’ll have to cut it open to look for a broken wire. Solder in a new section.
