Morning Robbi,
Your help was great... I have found out disconnecting the box makes the soft close work... So the trunk closing is not faulty and has never been... There is some clash between the car and the cabrio-roof remote module that makes the soft close work intermittent... Unfortunate as I though the module was great but I'll need to find another unit to do the remote open/close.... But I'm having a big break from roof work after this.
Buying a spare trunk close module is an unwelcome expense but I think having a spare unit could be helpful in the future...
And once again thanks and hopefully a decent weekend despite the lockdown...
Just wanted to chime in to let you know I just had the exact same thing happening to me. I also have the cabrio module from the same vendor, and for me also it started with the soft-close of the trunk not working; I had to SLAM the trunk to make it close. Of course the next thing that happens (since the car thinks the trunk is not closed properly) is that the car is telling something is wrong with the roof and it won't open/close.
I had to drive around like this for a while, since my BMW specialist was on vacation, so I had some time to investigate further (which made me find your message, thanks!)
I told my BMW specialist of your story, although I added that it sounded a bit unlikely to me, considering the symptoms. The guy is quite specialised in diagnostics & it took him less than an hour (possibly with some help of me pointing out your experience) to find that it was indeed the roof-comfort module... (he put a scope on it etc.)
Once that module was removed everything started working flawlessly.
I contacted cabrio-module.de and Andreas (Owner) asked me to send him the module for inspection. He just messaged me that he indeed found the module to be faulty and I will be shipped a new one, as it is within the 2 year guarantee period.
The initial symptoms did not make it obvious to me where the issue was to be found, so I just wanted to let you guys know about this experience so that you don't make a lot of costs to get to the root cause of the issue...
The only thing that I'm a bit worried about is that this is hopefully not going to happen again... Are there people here that have the same module and it has been flawlessly working for years? (for me it took only 7 months for the problem to show up)
