2009 ML350 4matic low speed hesitation
I just bought a 2009 ML350 4Matic. At idle engine is perfect, idles and revs perfectly, no codes, no check engine light, yet at low speed it will hesitate a bit, (you can almost feel it physically as a vibration in your foot when hitting the gas) then smooth out at highway speeds with no problems. The car is at my mechanics now. So far he has changed a front axle, driveshaft, ujoint, rear brakes, control arm bushing, tranny fluid flush, fuel filter in the hope's each one of these things would fix the issue. He said it is much better, but still is slightly there when car is cold especially. I also own a s550, but know nothing about ML's. Any help would be appreciated.
Also, I upgraded to newer ML rims and tires and that did nothing to help the issue.

When it is cold and coming to a stop does the car lurch forward or while stopped does it lurch forward?
If it does, the trans. fluid is low and or very dirty.






Many thx.
