Roof operation stops halfway

Where is the roof stopping, during opening or closing? There is a reasonable delay during the opening sequence, where the boot lid pauses whilst the roof is locked into position inside the boot. The 'dancing windows' issue can also require an additional press to complete the closing sequence but this only affects the windows after the roof has locked.
Does it 'bong' at all when it stops? If not then I doubt there is a fault, as per above it does pause during stages. If you are having to repress the button, you shouldn't be taking your finger off the button at all so just keep your finger on it and it should continue after the brief pauses.
I had a block with mine once and the bong happened as soon as it stopped (it was something on the shelf in the boot blocking it). Another time it stopped mid operation and again the bong happened, so I closed it and opened it again and it was fine.

Hi Guys
Yes it 'bongs' when it stops halfway. I have to repress the button then the operation carries on.
It does it on opening and closing

Are we talking dashboard button or key fob button?matthurley said:Yes it 'bongs' when it stops halfway. I have to repress the button then the operation carries on.

The reason I ask is because I have just had to change the battery in the key fob. Could this be your culprit?
Note: Only vehicles with comfort access have a battery that needs replacing.
Non-comfort access keys are inductively re-charged whilst "in the ignition"

In this case there is a fault, get it checked. If the roof actually opens and closes, at least you know it's not the mega expensive items such as motor or hydraulics. Sounds like a sensor which is a fairly easy to diagnose and relatively non expensive fix.

The fault occurs both using dashboard and fob button...

I haven't as yet...
I can still get the roof up and down with two depresses so not mega urgent. Not as if it wasn't working at all in which case I would have had it seen to by now

Mine has started to not open properly if the car has been sitting for more than 30 mins. It is like all of the oil has drained out of the hydraulic unit.
It will start bonging straight away when I press the cabin button, and the first and second actions are very "jerky". The lock on the third action then may or may not activate and then the roof just sits there. After a while of opening and closing to whatever stage it gets to, the roof finally opens. If I then close again, it will open up just fine with no bonging or jerking
Booked in on Monday, good job it's under warranty because something is seriously wrong with it.

I test drove a 3.5iS and on the day I turned up to drive it the previous test pilot had lowered the roof and it stuck halfway down. Their tech said it was a failed sensor. When i went back there was a lighting fault. Guess something was telling me that one wasn't for me 
Looks like I spoke too soon, mines playing up now, window section of roof sticking on top of the roof have to switch off ignition and restart engine again to get it to complete the cycle and close, when the roof is down the windows won't comeback up automatically neither with using the door window switches, also I have noticed that the radio station display changes when pressing the buttons for the roof.
Anyway we phoned them up yesterday and told them we are really pi**ed off with the whole thing and I'm going in this morning to see them, we intend to give them one more chance to fix it as we love the car but it will be rejected otherwise.

Right here is my update form today's visit (with pictures). Firstly, the god's obviously were not smiling on me today, was happilly pottering along to the dealer when I get a bong, TPMS goes off. Get to the dealer and confirm that my o/s rear is flat, at least the runflats were doing their job.
Anyway, back to the roof and the fault has been diagnosed as hydrualic pump failure due to water ingress, any guesses from where???

Mine goes in tomorrow, I will mention what they have found on yours at least they can eliminate that, have told them this is their last chance to fix it or i'm rejecting it and want either full refund + cost of having a tracker fitted or a replacement Z4 35is (they have another nice looking one same year, slightly less miles but a lot more spec)
I see rusty battery bolts too. Was that perhaps from those vents they did a recall on ages ago? Can't be roof seals can it.. Or worse the bloody rear lights? Although there's some mess on that battery top too!
I find it staggering this story hasn't ended with the e85. Put the pump somewhere it can't get wet, like in a sump!
