Hi, so after the winter my roof did not go down: windows went down, trunk got up, but roof itself did not move.
We attached the diagnostic program, deleted some roof error and after that roof went down perfectly.
However couple days later something like that repeated: windows went down, trunk went up but roof did not move. BUT after releasing the button and pressing it again the roof went down (previously releasing and pressing the button again did not help).
Now in order to take it down or up I need to press and release the button for 3-4 times. Example of how it works:
1st press - windows go down, trunk goes up. Stops. Button release.
2nd press - roof starts to go down, but stops in the middle. Button release.
3d press - nothing happens. Button release.
4d press - roof finally goes full down.
Similar thing when I want to get it up, takes even up to 5 press/release cycles till everything goes back fully up.

What could be the problem here? :(

Thanks

Any tips, guys?
I was driving and it started raining, it was pretty stressful to put it back up with few presses because of the thought - what if it would not close :D
Thankfully it closed, but I am worried if this thing would not work at one point or another..

You need another diagnostic.

Deleting the fault code doesn't fix the problem the car's computer is telling you.
The guy (non pro, just someone I found on forums) told me to check the fuses. He meant fuses in that compartment where you attach the diagnostic cable, said there are 12-16 or so fuses and I should check them.

He did not say in a very convincing tone so I am wondering if he just randomly guessed or that he saw something about the fuses in the diagnostic result.

Might it be the cause?

Update after one more chat with the guy who did diagnostics:

he said the error was due to too high voltage in "roof computer" (not sure the correct term).

I also spoke with one pro electronic guy (he did not do diagnostics on this car, just spoke remotely) and he also said something along the lines that:

may be due to too high voltage, computer is trying to prevent it from burning and that is why it stops the movement.

It seems that these 2 guys (one after diagnostic, another from his experience) were talking about the same thing?

Anybody knows something about it? Second guy said it may be an easy fix, but is unsure before he checks the car himself.

Thanks
