Aircraft X arrived to ZZZ with a ground time of 1 hour 24 minutes. the lead assigned to aircraft was [Mechanic] and two techns. Aircraft had a status message semi lever gear press left. All leads in the crew were monitoring the situation including the supervisor on duty. The technicians working the item were having a problem with the tooling used to service the strut. They were able to clear the message but the strut pressure was not at the proper level for dispatch per chart in the amm. The plane was in delay so I decided to go assist along with another lead [mechanic]. The supervisor on duty was already with the techs. I suggested to the supervisor and technicians to either find an alternate method to service the strut or find another strut servicing gauge. At that moment the supervisor on duty decided to go back to his office. Then management decided to sign of the log items including the mrd knowing that the pressure was not at Dispatch level. The plane took off. The message came back; and it was serviced at the next station. Have proper tooling available to support the aircraft and management should not circumvent procedures and releasing an aircraft knowing it was not ready for dispatch.
Maintenance technician reported that an aircraft was not serviced with the proper procedure; and was signed off and returned to service without being repaired.
