I think,this should work:

pawn Код:

public vDamage_Update()
{
    for(new playerid; playerid < GetMaxPlayers(); playerid++)
    {
        new engine, lights, alarm, doors, bonnet, boot, objective;
        new Float:vhealth;
        if(IsPlayerInAnyVehicle(playerid))
        {
            GetVehicleHealth(GetPlayerVehicleID(playerid), vhealth);
            if(vhealth <300)
            {
                SetVehicleHealth(GetPlayerVehicleID(playerid), 1000);
                GetVehicleParamsEx(GetPlayerVehicleID(playerid), engine, lights, alarm, doors, bonnet, boot, objective);
                SetVehicleParamsEx(GetPlayerVehicleID(playerid), 0, 1, alarm, doors, bonnet, boot, objective);
            }
        }
    }
}
