greg keep us up to date on how you do with the 07 ml
i have an 08 and have not had any big issues with it

bought it with 99,000 a year and a half ago
it is my back up car, have put 26,000 on it i think

mine did have the power steering issue replaced/fixed before i bought it and i few other things that were good repairs to have done and they were done under warranty with mb

did my homework before buying and knew it was a good thing that some of that stuff had been upgraded/replaced

i have had to do some oil hoses, the plastic part that holds the turbo inlet orange gasket was cracked and i replaced that- pricey
if you have any oil leaks i would start there, pull the whole thing out and check it over good, we could not see this from the top
i insisted the mechanic pull it all out and it was badly cracked on the bottom, but i think that entire piece has been upgraded now- hopefully i will have no more problems with it

no more oil leaks since then
mine has not had the oil cooler leak yet

i get 28.5-30 every tank - summer and winter
that is babying the gas pedal some

it has done awesome in the mud for me on my dirt road to my house, that is why i bought it

so far my truck has been very reliable, other than the small oil leaks no problems

i am not a huge fan of the way it rides, changed the shocks/struts and it may have helped a little but did not think it rode much better
just a little harsh and too truck like for me

other than that have been very happy

good luck with yours

Tailgate issues - check your battery - I suspect the pump times out if you have low voltage and it can't build enough pressure.

With all doors closed put the key in I position (just the radio on)
Press the R button 3 times in the center of the cluster
The LCD should show you the battery voltage
Glow and crank the engine and see what the voltage drops to.

Mine was going down to 9 volts on glowing and 6 volts on cranking
W164 battery replacement

Once I replaced the battery last February I have not had any issues with the tailgate since. Even when parked with the rear end up on my sloping driveway. Not sure if it was the better voltage or cycling power that did the trick but it definitely did for me.

If you run WVO on the 642 engine you need to reflash the ecm and get rid of the post injection cycle and DPF. It will clog faster, run the cycle more often and the byproducts of WVO will end up in the engine oil from the post injection cycle and the oil will turn to jelly-sludge. This has nothing to do with the quality of the fuel, just byproducts of the oils used. Change the oil often and delete the DPF for long life or you will hate the vehicle.

I love mine, it has been 3.5 years now and 60k miles of bliss, just ran 5k mile trip to Florida with 3 adults and 2 kids, 5 weeks and just an amazing machine. Even with a huge Thule box on the roof, cargo rack out back it still turned in 28-30mpg USA, running a good speed but easy on the uphills. It really disliked Florida diesel fuel, not sure what % of biodiesel is mandated as some pumps were labeled B20 (which I avoided) and others were not labeled anything but it was not great fuel, tank was usually empty at 500 miles, vs minimum 600 average.

on my tailgate issues i already have a new battery in the past year

mine seems to screw up in the locking mechanism at the bottom, it is not weak to lift it or close it

it start to open, get stuck and then close again before the latch ever lets go

priced the latch/lock a while back and it was 300 i think, just been too busy to mess with it

i did adjust once and that seemed to help some for a while but still the occasional mess up
