Hi, my name is***** can be for any one of the limit switches. It can also be caused by low hydraulic fluid. You will need to check each one of the limit switches individually. I'd try lowering the roof manually then erasing the code then see if the roof will raise. If you have low fluid the roof will not raise. Sometimes just lowering the roof manually and then raising it with the switch will solve the problem.

Let me know how you make out.

Also make sure that the luggage cover is in place. If the switch is blinking rapidly there is a problem with the luggage cover or the trunk lock. If it's blinking slowly there is a fault with a micro switch or with the pump circuit or fluid level.

Can only open trunk with top full open
If top is up trunk doesn't release with fob
Button on trunk doesn't release trunk even if top fully open
Key slot is straight up and down

Insert the mechanical key into the lock and rotate it all the way clockwise and hold it there then push in on the lock to open the trunk.
