E93 335i Roof stuck in trunk

I seem to have struck the most feared issue on an E93, the convertible top is not working

My roof package is in the trunk but now it won't come out (I left the roof open for slightly more than a day, while parked in the garage). When I try to close the roof with either the key or the switch, the trunk lid opens, then there are a couple of faint clicks but the roof package does not come out and the trunk lid is stuck in the open position. If I hold on to the switch the red indicator comes on indicating the roof is not locked properly.

I have tried manually pushing it while pressing the key button but to no avail

My guess is because the trunk lid is functioning it is probably not the electric motor but either a micro switch or hall sensor. I am not getting any error messages so can't say which of the micro-switches or sensors is the issue. I even tried looking up the error codes through an OBD II reader but that also shows no errors.

Anyone else experienced this issue or any idea what could be wrong?

There are only hall sensors in the modern BMWs.To check the proper signal from the sensors you need ISTA/D or DIS.I have fixed more than one convertible by looking at te actual values on the screen and comparing what they should be.Usually where the sequence is interrupted,the problem should be in this area.If I am not mistaken,the hall sensor for "trunk fully open" is on the hydraulic cylinder that opens it.I have many cases when the sensor were just loose/misplaced.
Good luck fixing your problem.
