В итоге сработал вот этот код фильтра + указать в параметрах catalog.section после фильтра
"BY_LINK"=> "Y",
"SHOW_ALL_WO_SECTION" => "Y",
"SECTION_ID" => '0',
<?
$arFilter = array(

$arFilter["ID"] = $arResult["VARIABLES"]["SECTION_ID"];
}
elseif ('' != $arResult["VARIABLES"]["SECTION_CODE"]) {
$arFilter["=CODE"] = $arResult["VARIABLES"]["SECTION_CODE"];
}
$obCache = new CPHPCache();
if ($obCache->InitCache(36000, serialize($arFilter), "/iblock/catalog")) {
$arCurSection = $obCache->GetVars();
} elseif ($obCache->StartDataCache()) {
$arCurSection = array();
if (Loader::includeModule("iblock")) {
$dbRes = CIBlockSection::GetList(array(), $arFilter, false, array("ID"));
