SL63 AMG, prior to that A-M V8 Vantage, SL55, SL500 and many more
My SL has the optional power boot opener/closer. Sometimes the feature doesn't work - pull the boot handle & it unlocks but doesn't lift. Other times it won't close when I press the button to close but I do hear a clunk (like a heavy relay) from the area of the roof pump / PSE.

No major prob - it seems to be fine the next time I go to use it after the car has been locked.

However - sometimes the roof won't go down or go up, like this morning & I think it's a switch somewhere

Sequence today:
I open the boot by pulling the handle - it rises, I put my stuff in the boot.
I press the button to close the boot - it closes.
I go to the drivers door (keyless), it unlocks I get in & start the car.
I lift the handle to drop the roof - the windows drop slightly but then nothing - the bootlid doesn't open up as per normal
I get out & go to open the bootlid per normal - it unlocks but doesn't rise. I lift manually to fully open, press the close button & it closes.
Get back in the car, pull the roof switch & it drops fine.
Get to the office, park up & press the roof switch, windows drop but boot doesn't open.
Switch off, open boot manually (power open doesn't), close manually, lock, unlock restart car, press switch & roof comes back up per normal.

For anyone still awake (sorry!) it's understanding the roof switch by virtue of the windows dropping slightly when trying to raise/lower the roof - just sometimes it doesn't follow through
It's understanding the boot handle (and remote) to unlock & open - just sometimes it doesn't follow through.
It's understanding the close boot buttons - the click from the pump area but do nothing and even the fold mirrors in / alarm when I press the close + lock switch but the boot remains open.

A reset by locking the car seems to get it to behave again every time whichever bit has misbehaved so I'm thinking there's a switch somewhere that's not properly responding but I have no idea where it/they live but something to do with the boot lid seems the lowest common denominator

No dash errors when the roof plays up - it's just like I've started then let go of the switch.

If anyone has any suggestions, I'd be very grateful to receive them

Many thanks in advance
David
