Thought I would provide an update. Towed it to the dealer. Apparently, my ECM experienced a voltage spike and stopped communicating. Thats why no resets worked and my computer would not show any errors. No way to fix it. Only fix is to get a new ECM. The dealer replaced it and my truck is back to normal. Total cost $2515.28. Apparently ECMs can only come from germany and each one is vin specific. You cant get one from a junk yard or of ebay. Dont know how much of this is a crock of you-know-what but my ML is running again.
