I recommend checking these points before you test it with a new relay...

TROUBLESHOOTING ON THE RELAY CONTROLLER
Note: Control relay disconnected. The terminal designation on the relay (Fig. 596_97) is from the underside of the control relay.
1. connect the measuring device (voltmeter) to terminal 22 (earth) and terminal 23 (plus 30) on the relay plate. Display = battery voltage
2. connect the measuring device to terminal 22 (earth) and terminal 26. Switch on the ignition. Display = battery voltage
3. connect the measuring device to terminal 23 (plus) and terminal 15 (handbrake applied). Display = battery voltage
4. connect the measuring device to terminal 23 and terminal 16 (close soft top button). Press close button. Display = battery voltage
5. connect the measuring device to terminals 23 and 17 (open soft top button). Press the open button. Display = battery voltage
6. convertible top locked . Connect measuring device to terminal 23 and terminal 14 (microswitch wind frame). Display = battery voltage
7. convertible top locked . Connect the measuring device to terminals 23 and 29 (microswitch B-pillar). Display = battery voltage
8. top unlocked. Connect the measuring device to terminals 23 and 13 (microswitch closed, soft top compartment lid VDKD open). Display = battery voltage
9. convertible top unlocked . Connect the measuring device to terminal 23 and terminal 19 (microswitch wind frame). Display = battery voltage
Connect control relay to relay carrier. Open the soft top compartment lid and disconnect the electrical plug connection on the drive motor-top drive.
10. connect the positive of measuring device to terminal 1 (black cable) and the negative of measuring device to terminal 4 (green cable). Kl. 2 and Kl.
11. connect the positive of measuring device to terminal 4 (green cable) and the negative of measuring device to terminal 1 (black cable). Bridge terminals 2 and 3 with an auxiliary cable. Switch on the ignition and press the "Close" button. Display = battery voltage

Btw, afaik from 2000 onwards there are only two microswitches, one in the lock and the other in the planetary gearbox. No microswitch on the bracket of the motor.
