I can't remember properly now but when you pulled the emergency lever you've disengadged the motors in the boot lid
Think you have to click the motors back in and if i remember correctly on the m3's there on the left hand side when you open the boot behind the carpet. They just click/push back in
Then you have to put on ignition and hold the hood switch or something
try this site and just google with (e36 convertible reset)
