ok i know that there are lots of people having the problem where the ml does not accelerate as it should and in total a power loss on the ca, i have struggled with that for some months, and was told the airflow sensors are faulty and lots of other stuff, i took it in and then the main problem was gearbox oil level was low and the filter were dirty as hell, got her back and she as driving like a brand new car. so truly get that checked first and also make sure that the orange turbo seal is also intact.
