2003 Mercedes Benz SL500 Convertible roof

Hello .. thanks for the donation .. much appreciated

The roof should lower itself to the end position after 7 minutes of being stopped in wrong position .. if this does not occur .. something must be jamming it from moving .. you need to have a tachnician look at the vehicle ..

Monitoring of roof function
The vario roof operating sequence is stored in a sequence table for each direction of motion, which is compared with a search function (determines the current position of the vario roof). If these values do not coincide, either an emergency operation is performed or the vario roof sequence is interrupted and an error message is sent to the instrument cluster, depending on the error which has occurred.#
If the vario roof operating sequence is interrupted, the stop function is activated immediately, moving the vario roof to the end position in a controlled manner.
The following criteria interrupt the vario roof operating sequence:
Releasing vario roof switch
C. 15 OFF
Low voltage in vehicle power supply
Vehicle speed (v > 5 km/h)
Lock pawl rotary tumbler switch open
Trunk partition not closed (applies only for opening of vario roof)
Roll bar crash deployment active
Interrupt conditions resulting in damage or exceeding actuating request time
If the operating sequence is interrupted and the vario roof is not in a confirmed end position, the stop function becomes effective. It holds the vario roof hydraulically in the current position for t=7 min. If the stop function cannot be revoked by this time, the vario roof moves to the nearest mechanical end position under its own weight with hydraulic damping.

hope this helps
