I have a CLK 350 (W209) cabriolet. The manual opening (release) handle on the boot will now suddenly not work when the rest of the car locks are opened on the normal "all open" button on the remote control. Please - any ideas?? To clarify: - The boot lock opens fine when either the boot release button (on the drivers-side door) and/or the boot-only button on the remote is pushed. - The manual boot handle works fine with the emergency key. - I have tried the factory remote-locks reset (by pushing both the open and close buttons on the remote) - no change there.... - I have sprayed 3-in-1 into the whole lock - and the solenoid sounds 'nice' (but still the handle will not release on the usual 'all open' remote button.
