The roof opening panel is an electronically operated panel that can be opened or closed by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel motor. The vent and soft-stop functions are controlled by the roof opening panel motor. These positions are obtained when an internal motor cam opens the roof position switch, removing the ground from the switch. The roof opening panel has an express open feature activated when the switch is pressed momentarily. The roof opening panel is closed by continuous activation of the switch until the sunroof stops movement. This function is controlled by the roof opening panel motor.

Key in OFF position.
Disconnect: Roof Opening Panel Motor C920.
Key in ON position.
NOTE: Activate accessory delay relay for this check.
Measure the voltage between roof opening panel motor C920-4, circuit 400 (LB/BK), and ground; and between roof opening panel motor C920-7, circuit 1173 (BN/OG), and ground.
Are the voltages greater than 10 volts?
Yes
GO to E7 .
No
REPAIR circuit 400 (LB/BK) or circuit 1173 (BN/OG). TEST the system for normal operation.
If you can't do electrical testing , there is a manual way to close it .
Roof Opening Panel Manual Operation
Remove the overhead console. For additional information, refer to Overhead Console in this section.
Insert a hex-head screwdriver in the center of the manual drive slot to depress the release pin. Rotate the screwdriver clockwise until the roof opening panel is closed.
Only by using the emergency manual override process which you'll find in the vehicle owners' handbook. But it is intended for occasional emergency use only such as when the roof electrics fail. Regular usage can cause additional problems. If the electrics fail then it's recommended to use manual override to close the roof and to keep it that way until you can get the roof mechanism fixed.

no need to convert.
the electic roof can be opened manually by:-
unlock the roof using the handle on top of the windscreen and push roof back as far as posible.
lift flaps adjacent to door pillers
you will see a small lever which can be retracted (both sides)
when these levers are retracted the roof will push down fully into its compartment
when erecting the roof ensure that the two levers are fully open to accept the roof retaing lugs
I have a 206 cc of production year 2002 and the following solution worked for me. My problem was that the roof would not close anymore electronically and there were continuous (and annoying) beeps when driving. Following solved my problem: 1. Followed instructions to close the roof manually. This you can normally find on your cars manual. Alternatively have a look at video above for the manual closing of the roof. 2. After successfully closing the roof manually re-position the jumpers to automatic locking position. and re-tighten the depressurization bult. 3. Open the roof normally with the electric roof-switch. (check that the net at trunk is also closed). These steps helped me reset the automatic roof mechanism.
That is not the problem the problem is your convertable roof is not closing properly to test this let someone press down on the roof lid and then try to open the trunk, To fix this let the roof lid open and let the roof come up until the back part stands up to let the roof lid close so that the roof hold is exposed look on the right hand side of the car (if your standing at the back) under the roof lid catch there is a small plastic buttun that the roof lid catch needs to pres down on, this tells the car that the roof lid is seucre and it is now safe to let open the trunk, All you have to do is set the tension on the cable for that roof lid catch and the problem is sorted.
I just bought a 1996 328iC (the "C" is for convertible). I bought the car with the knowledge that the roof needed a motor replacement (~$300 for the part alone + ~1-2 hours labor) and that I would need to open and close the roof manually if I wanted to take advantage of the convertible part of the car.
After some trial and error, I figured it out and now it takes me <30 seconds to open or close the top (manually). Note: my top is a semi-electric roof, which I think is what came on the 328iC, you have to lock into place after you close it.
Here's what you do: 1- open all of the windows 2- unlock the roof by turning the latch between the sun visors. 3- push the front of the roof towards the rear of the car - be sure to push in the middle of the roof, where the latch is. 4- lift the back of the roof up off of the roof storage compartment 5- while holding the back of the of the roof up, lift up the roof storage compartment door 6- let go of the back of the roof so that it drops right into the storage compartment 7- push the rest of the roof into the storage compartment 8- close the storage compartment door.
To close the roof, follow the steps above in reverse order. Remember: this is a German car, so you use a little bit (or a lot) of force and you won't hurt it (I think it actually likes it ;-D ).
Open roof latch over windshild.
Raise rear of roof off of hatch
Lift little hatch tabs to access lift mechanism
Release latches on each side with fingers
Lift Hatch with free hand
Let roof fall into storage compartment
Click hatch shut.
Reverse proceedure to put back up.
