swordfish767,

welcome to the forum! I see that you posted the same questions on benzworld.org. A little more detail would be helpful.

1) Have you checked the fluid level in the pump (under the spare tire)?
2) Has the top been moving very slowly, lately?
3) Have you tried locking the front with the soft top tool (6-mm Allen wrench)?
4) Has any work been done to the front lock cylinders above the windshield?

Looking forward to your detailed answer.

Klaus

Please lock it in the front with the Allen key, and let us know if the rear closes after that. I suspect bad piston seals in the front lock cylinders 1298001672.

Hi Klaus, thank you for the help.
The problem was in the right front lock.
