Not sure if they are the same or not, I have what seems like recurring problems with air leaking near and around the egr. I usually either get my 22m or my hex driver out and tighten the culprit. I found my locktight for next time it happens.
Although with a trade-in its near future I dont think I'd be spending $150+ for a new one.
