I just received a call from our service advisor at Greenway Mercedes in Houston, TX for our 07 ML350 with 43k that our CEL error was on the bad end and the quote of aprox. 6k would be covered under MB. Our ML fell outside the warranty time period a few months ago but still within the 50k. Our advisor fought for us and had it covered.... We were speechless when we received the call and immediately went over there and thanked him with a generous gc from Starbucks. We're one of the lucky ones!!!
