I just replaced the hydraulic pump on my SL. Everything works except for the trunk. Trunk will power open, but will not close.
Does anyone have any ideas about what the problem could be.

Are you sure this car has a power close? I didn't think it was an option. It has an auto release and soft close but I'm not aware of any with power close.

Are you talking about the trunk opening and closing with the top?

mine is not trunk assist
but i have had the trunk shocks and the latch replaced which included the sensor seal for the vacuum close

if it closes but wont seal then its a 2-400 job....buy the part in advance and have someone replace vs dealer ad hoc

I'm having a bit of a hard time trying to understand but I think you may want to have a look at this thread;

I have a 2007 SL600. It comes with power trunk.........both to open & close.
I replaced the hydraulic pump myself........2 weeks ago.
Now, the roll over bar works..........the vario roof works.........the door locks work.........the trunk will power open, but will not close. When I press the trunk close button, the pump buzzes but the trunk does not open.
I think I may have missed something.........does anyone have any ideas.

Ah, makes more sense now. I was reading your profile that says a 2005 SL65. The only thing I can think of is a vacuum leak somewhere. I see you are in Atlanta, I have a great Indy who's very reasonable if you want to head that direction.
