Had our 2000 ml320 flatbeded in the dealer today. My wife was pulling away from an intersection making a left turn when she said that the trans would not shift out of first. She could not go over 10mph. No warning lights on. Ets light has come on several times before and I was going to advise the service writer at the B service, which I will have performed now that the ml is there. The dealer called back later that day and said they found no soft or hard codes of any kind and was there a possiblity that my wife could have engaged the low range 4wd. I asked, she said no. The tech at the dealer roadtested and all is well. Any ideas? BTW the ml has 30,000 miles on it at this time.
