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.
