Hello, currently have the above error message, All lock have been checked. Go in and out again. Only the third lock will not be red at the lock switch in the cockpit. Vehicle says lock is active, although all lock if I do not activate you are not active. Did anyone ever have such a case or can help me ? What has already been done: vacuum pump has been checked. Low pressure has been checked locks have been vented. All locks have been checked for consistency Membrane on the VG has been built apart and tested
