What is the current physical status of your car - like this or different?This is extra, I also print all sensors states
Yes it is like this.What is the current physical status of your car - like this or different?

It can be locked and unlocked with INPA: CTM, F6, lock or unlock cowl panel (F4?) => I don't know the exact wording in INPA.Yes it is like this.
I played with some activation, and figure out I unlock the pack in the trunk

Previously I lock it manually by connecting power direct to the motor.
Softclose is a function of the locking system in the trunk lid, but has no functionality on the roof/rams!Also not fully understand soft closing and locking,
The wording is not quite correct:...the ram will pack the shells in the trunk, then motor will lock them in place "cowl" , then ram will close the lid, the soft close "who is responsible" the locking mechanism or whats called latch.
When / how / by which activity? Or just by decreasing´/loosing hydraulic pressure over time?BTW, there is an activation for my car at this position, the lid lowered a little then back again, not sure how??!!
I don't think so, as this is a different view without errors.I guess the contradiction because when I used JBBF, I got error, but I forced INPA to proceed

Hui, so many screenshots!
- No blockers on the prerequisite pages, great!
- Windows seem to be a problem, that should be solved:
And the solution is also known, but one condition of the solution is not applicable....
- The car has lost the learned min/max positions of all 4 windows! That's weird.
Currently I'm not sure, if it can be re-registered while the roof ist not completely closed and locked.- In ISTA a registering process can be executet, but all doors and the roof have to be closed. Similiar in INPA.
I tried, but it is not locking.It can be locked and unlocked with INPA: CTM, F6, lock or unlock cowl panel (F4?)
INPA: CTM, F6, SCA aufWhen / how / by which activity? Or just by decreasing´/loosing hydraulic pressure over time?

I'm not so optimistic, as this issue doesn't explain your initial fault when closing the roof.This is a complete success, now, we know the source of problem and it is a matter of how to solve it..... Great....
And the solution is also known, but one condition of the solution is not applicable....
Pardon, but this is the wrong function: it means SoftCloseAutomatic - => trunk lid only.I tried, but it is not locking.
INPA: CTM, F6, SCA auf
eo
Correct, butFor windows initialization, this is the page

Could you please post a screenshot of your INPA CTM F6 page?It can be locked and unlocked with INPA: CTM, F6
But not in this very special case.TIS makes life so much easier
To shed some light on it for a better understanding:Pardon, but this is the wrong function: it means SoftCloseAutomatic - => trunk lid only.
YES. This is a task of the main pillars with the 2 rams on the bottom of the trunk.Also not fully understand soft closing and locking...
As far as I know,
- the ram will pack the shells in the trunk,
YES. This is done by the central motor of the front locking system.
- then motor will lock them in place "cowl" ,
NO. The rams on both sides of the trunk will close the auxiliary frame!
- then ram will close the lid,
NO. SCA is responsible only for the trunk lid.
- the soft close SCA "who is responsible" the locking mechanism
The latches are the two hydraulic cylinders (rams) on both upper sides of the trunk, which won't finalize the latch/locking operation of the auxiliary frame due to wrong / incorrect / missing sensor signals.
- whats called latch.
I've just tried, with no successPardon, but this is the wrong function: it means SoftCloseAutomatic - => trunk lid only.
Correct, but
- doors and the roof(!) have to be closed perfectly
- the ignition has to be activated - start button pressed without starting the engine, all led's on the kombiinstrument (dash) have to be activated
I tried to reduce number of screenshootsCould you please post a screenshot of your INPA CTM F6 page?
The same frome the JunctionBox, JBBF F6.
Currently I don't have access to my Z4 to check the correct function names.



This switch is only for much elder cars like 3-series E46 and older. If you get a connection to INPA, the switch position is fine. I assume, both positions will work fine in our E89.Question, For the K+DCAN cable, the switch should be to the right or left, and does it depend on software used "i.e. INPA or ISTA" or the vehicle and model?
As expected.I've just tried, with no success![]()

Thanks.Excellent explanation...
Let's postpone this as a future task. No idea right now.So what is the solution now for the front windows,,,,showing closed while it is fully open... I think because the man in the workshop override and open and close the window... But how can I fix it now??!!
The key FOB has to be inserted into the key slot. Ignition is not required, just the FOB placed into the slot.Cowl lock position was not changing, is it because I should press the start button but not starting the engine?

I jumped the connector by direct connection to the motor poles, I wish I did not damage the CTM doing thisDid you place the 2-pole connector back onto the CTM?
Yes it is unlock, but I figure out by inserting camera pointing toward the lock cowl while you red the status "smart"This motor always has to work fine controlled by INPA. I generally use it with INPA when a roof doesn't work any more.
Current status: unlocked!
I'm pretty sure just the key FOB is required to be inserted into the slot. An activated ignition is no blocker, but will empty your battery.To lock it again using INPA the car should not be starting, correct?
No, should be fine if the 2-pole plug was not connected to the CTM while experimenting with an external power supply. But now it has to be plugged back onto the CTM to be executed with INPA.I jumped the connector by direct connection to the motor poles, I wish I did not damage the CTM doing this
Your picture from above shows an unlocked system:Yes it is unlock, but I figure out by inserting camera pointing toward the lock cowl while you red the status "smart"

Hello fellow Z4 owners,
![]()
I'm seeking help with my 2011 BMW Z4 E89 SDrive 23i. My retractable hardtop has been malfunctioning. This started while ago. Sometimes it did it initiate while opening or closing, I leave the hardtop at that position either closed or opened for a week or two, then it working fine, but they persist.
Last time a month before when it was in closed position, I try open the roof, both shells went into the trunk but the lid not closing. so i waited in that position for a week, but no luck. error like not latching then A6A5 code appears everytime I try to open or close the roof.
