Hi klaus, You rebuilt one of my cylinders for me last year, great work thank you. I've got the interior panels out of the trunk trying to clean things up a little better. I've been running with out the window shade baggage cover in place, just jumping the sensor switch using a wooden clothing pin. I got the top almost shut with the rear glass window section caught by the tanno catch but not pulled down all the way. I think this is because the cloths spin popped off. So now the switch does nothing, no up or no down. I have tried both manual trunk keys even with as much plier pressure as I dare but no luck. My plan is to use the wrench to lock the roof down to the car (roof up position) which should clear my alarm allowing remote to open trunk and fix cloths pin and finish inside trunk repair.
