E89 roof won't open

The 80ah battery definitely won't cause a problem..but..your readings from your OBD reader suggest inconsistent battery status ...
So often on E89s a simple A/B swap helps eliminate gross errors
Varta is a very good brand and it seems unlikely..but..it happens all the time..
As Chippie said corrosion on the CTM connector pins or water inside the CTM MAY be issues..again we've seen them here

Can a wrong battery status bring other problems ? Roof opening ? Others... My OBD reader gave me a list of errors and I am checking them all...

On my 35is when I bought it ..it had 145 errors..most cleared with a new battery and error clear
Clear the errors and see which come back
... or defective vents on both sides! Can be replaced from the inside of the boot.
There's a fucked-up drainage system under the car, at the vertical of the battery. A button/cork, could not see clearly, had to keep my finger pushing it to evacuate the water, just a trickle, took me 10mn, need to have a proper look at it when I can get under the car more easily
Maybe the Kombi is not sending an appropriate speed message to the CTM to allow it to start opening?
That is not correct.
Don't search or even build a drain, identify the source of the water!
I don't know where it is exactly inside, "below the battery" was to position it approximatively.
You can find it under the car, when I pushed on it, water trickled and I was able to empty the water that was inside the battery compartment.
Ground was soaked, I did not look too much.

Hello everyone!
Here is some news about my car and the roof that refused to open.
The hydraulic unit compartment was drowned, the leaking taillight seals were changed.
The hydraulic unit was in a bad state but I didn’t change it. A handyman friend has completely “cleaned” and reinstalled it. He managed to open the roof in part until a fuse slammed. The part in question was the "electrical distributor with fuse" (Ref 61149192164) located just to the right of the battery.
We replaced this part, and the roof was working properly.
Unfortunately, last week, it started working erratically.
Here is the description of my concern, I know it happened a lot...
It works properly from time to time, but more and more often, here’s what happens: when I try to open, the opening sequence is done entirely, but the last step (= windows up) don’t happen, and the red opening light flashes red and the trunk remains locked, the windows refuse to open.
When I try to close, the roof closes, but usually stops in the intermediate position, 1st part of the closed roof, rear window above it...
And I can repeat the sequences several times, without success.
Last night, we could not close it anymore, so we wanted to put the car in the shelter in his garage, it’s a bit “bumpy” and when I was finished parking the car, I tried one last time and the roof closed totally, properly...
It is very similar to an opening/closing sensor problem...
Visually, the wiring looks really clean.
Here is the diagnosis OBD Bimmer Link
A69E: Speed too high ok, normal, I drove with the problem
A698: Top hatch open ok, normal
A6A3: temperature sensor the hydraulic unit motor is hot, it is functional, but it has suffered, I will have to change it
A694: Hall sense VSW8 it looks like the culprit!
This is the Bimmerlink diagnosis, but when you look for this error code, you find for “ctm_89” Microswitch ‘cowl panel reached’ for A694
Voili sailou
I will check the beam even closer, but especially watch the microswitch "B 3" 'cowl panel reached'

3¹/² months - what a long lasting story.
Well, I've already answered in the french forum.
