This will stop the whole callback if AutoRepair isn't allowed for a player.
Replace "return 0" with "continue", this will jump to the next ID if AutoRepair is disabled for a player.

If you set the timer correctly, it should then work as expected.

Troydere's solution is still better, since it will not require a timer. You can also use OnPlayerWeaponShot to restore any health that a vehicle lost by shooting.

PS: You can use GetPlayerVehicleID to determine if a player is in any vehicle (will return 0 if player is not in a vehicle), also RepairVehicle also restores the health, no need to set it seperately.
