Hi there

I had the same problem I com keyed manual reset but made sure windows down before starting then folded roof back and manually locked with key under back seat compartment before turning on ignition and holding open switch for roof for 20 secs and light went out. Turn off ignition then manually closed roof and locked with key before performing same by turning on ignition and holding switch down for roof again 20 secs and the fault went away. Tried again normally and roof went through full cycle
