TIS makes life so much easier
Roof service past error A6A5 and trunk stuck open shells in but not latched
- Thread starter khalidfh
- Start date
Hui, so many screenshots! 
- No blockers on the prerequisite pages, great!
- Windows seem to be a problem, that should be solved:
- 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.
- This page confirms that both front windows are closed, both rear windows are open.
The contradiction is, that the registration of all 4 window positions is missing.

Yes it is like this.What is the current physical status of your car - like this or different?
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.
Also not fully understand soft closing and locking...
As far as I know, 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.
BTW, there is an activation for my car using INPA at this position, the lid lowered a little then back again, not sure how??!!

I guess the contradiction because when I used JBBF, I got error, but I forced INPA to proceed
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.

Softclose is a function of the locking system in the trunk lid, but has no functionality on the roof/rams!
Finally, a "softclosed" trunk lid locking system is a prerequisite to start the roof opening/closing process.
The wording is not quite correct:
... then rams will close the support/auxiliary frame, not the trunk lid!
When / how / by which activity? Or just by decreasing´/loosing hydraulic pressure over time?

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....
I tried, but it is not locking.
INPA: CTM, F6, SCA auf
ISTA was removed "I will reinstall it" when I download the new INPA so I could not open the trunk lid to see what is going on from insideH But here is a video
For windows initialization, this is the page

I'm not so optimistic, as this issue doesn't explain your initial fault when closing the roof.
Currently I only see a required step on the todo list.
Pardon, but this is the wrong function: it means SoftCloseAutomatic - => trunk lid only.
Correct, butFor windows initialization, this is the page
- 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
Could 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.

To shed some light on it for a better understanding:
YES. This is a task of the main pillars with the 2 rams on the bottom of the trunk.
YES. This is done by the central motor of the front locking system.
NO. The rams on both sides of the trunk will close the auxiliary frame!
NO. SCA is responsible only for the trunk lid.
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.

I've just tried, with no success
I tried to reduce number of screenshoots
, For CTM
For JBBF
When I select JBBF I got this error
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?

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.
As expected.I've just tried, with no success
As mentioned earlier:I tried to reduce number of screenshoots
CTM, F6, F4 or Shift+F4 for the front locking system, even if the whole package is lowered into the trunk.
| German | English | Arabic |
|---|---|---|
| F6 Steuern | Control | |
| F4 Verriegelung auf | Unlock cowl | |
| Shift+F4 Verriegelung zu | Lock cowl | |
| F5 Status Hallsensoren / Schalter | Status hall sensors / switches | |
| Schalter Verriegelung vorn geschlossen | Switch cowl panel front lock closed | |
| Schalter Verriegelung vorn geoeffnet | Switch cowl panel froint lock opened |
INPA CTM F5 hall sensors / switches
INPA

Excellent explanation...
Cowl lock position was not changing, is it because I should press the start button but not starting the engine?
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??!!

Thanks.
Let's postpone this as a future task. No idea right now.
The key FOB has to be inserted into the key slot. Ignition is not required, just the FOB placed into the slot.
Did you place the 2-pole connector back onto the CTM?
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!

OK...
I jumped the connector by direct connection to the motor poles, I wish I did not damage the CTM doing this
Yes it is unlock, but I figure out by inserting camera pointing toward the lock cowl while you red the status "smart"
To lock it again using INPA the car should not be starting, correct?
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.
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.
Your picture from above shows an unlocked system:

I you won't be able to drive this motor with INPA (CTM, F6 Steuerung, F4/Shift F4), I assume this could be the source of your initial problem.
When you open the roof, the roof package get's lowered into the trunk. Next step is locking the cowl panel while the auxiliary frame (with the trunk lid on top) is getting down like on your picture. If locking doesn't work, the process might get stopped.

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.
