Sometimes when I press the trunk button inside the car, on the key remote, or squeeze the handle on the remote, I just hear a couple of clicks from the trunk, but it doesn't.
However, sometimes, with all three of the above options, I hear a clunk sound from the trunk, and it opens.

In both instances, turning the key in the trunk, 90 degrees to the left, opens it.

I have not turned the key 90 degrees to the right, to disengage the trunk from the central locking system.

Is there a settings somewhere that is wrong? The trunk usually opens electrically atleast twice a day, and I'm forced to open it manually another
2-3 times.

Had a similar problem but it went away all by itself. Totally weird!

Sorry I couldnt help.

The trunk just unlocks when you say opens right, it doesn't actually go up itself without touching it?

the locking mechanism is pretty weak on the 528, and may be starting to go (cracked plastic, getting ready to break). It is not a hard job to pull it and inspect.

(and "open" means it unlatches and opens an inch or so)

It opens about a 1/4" or less. Is is suppose to go further, or much further?

How do I replace it?

How do I replace it?From my experience, unlocking the trunk does just that, it doesn't "open" the trunk, it just unlocks it. You have to open it yourself (lift it up). From a distance an unlocked trunk doesn't look any different from a locked one. There may be 1/4 inch or less difference.

yes and i want to retro-fit one in mine! it's the hotness when you don't have to slam the trunk... just gently place it down and it locks by itself.

How do I replace mine, and make it function correctly? The trunk does not always unlock electronically (handle or remote). It always unlocks when I turn the key to the left in the trunk's keyhole. I have NOT turned the key to the right to disengage the trunk from the central locking system.
