Narrative:

Unable to steer aircraft off of active runway with nosewheel steering after landing. At some point approximately three hours into the flight; we received the two ECAM warnings listed below: wheel north/west strg fault bscu system 1 fault. Company ECAM procedures were complied with and the ECAM was cleared. Company QRH procedures were complied with and operational aspects were noted. The airbus supplemental manual was referenced for more information on both of these ECAM warnings and the operational information was noted. The wheel north/west strg fault would prevent any auto rollout features but this was not a problem due to good weather at our destination. The bscu system 1 fault was a 'crew awareness' issue. After a normal landing; the captain assumed control of the aircraft at approximately 80 KTS. As pilot monitoring; I noticed as we slowed that the captain appeared to not be able to steer the aircraft off of the runway with the nosewheel steering system. The captain bought the aircraft to a complete stop and advised the tower controller that we would be unable to clear the active runway. The tower controller acknowledged our radio transmission. The tower controller re-cleared an approaching company flight to land on runway xxl. While the captain was communicating with the tower controller; I switched the nose wheel strg switch to the off position and after a few seconds back to the on position. This action allowed us to regain control over the nose wheel steering system and we were able to clear the active runway. As we taxied to the gate; the original ECAM warnings re-appeared. Once on the gate; I called the tower controller to briefly explain what had happened and to find out if they would require more information concerning the event. The tower controller advised that they required no further information and a telephone call would not be necessary. At this time; the airbus QRH shows only that the wheel north/west strg fault affects the auto-rollout performance of the aircraft and that both of these items are a 'crew awareness' issue. I would suggest that the QRH be revised to include that these system faults may result in the loss of the nosewheel steering; as it did in our particular situation. Additionally; a QRH re-set procedure for the nosewheel steering system should be developed.

Title: An Airbus flight crew received an ECAM WHEEL N/W STRG FAULT BSCU SYS 1 FAULT in-flight. They ran the procedure and landed normally but then found they had no nose wheel steering and noted the procedure did not warn of this.
