Also do a battery cable and battery check..
I have also seen ML's do very strange things when battery cables have become loose or more often a bit corrded at the connection ..... I have seen "all warning lights" come on with battery on last legs with voltage up and downs..even some alternator problems (and there was a limited recall there)...
I would say back-to-some-basics-easier things for DIY check before surrendering to the sophisitcated and expensive...mileage seems low for some of the obtuse, but mileage and age is about right for some of the more basic tro check first...
