w164 350 diesel kickdown

[Gh3382]

I have a W164 ML 350.

At lower speeds when the accelerator is pressed hard down you can feel the boost and kickdown, but at higher speeds 60 - 70 ish it doesnt seem to kick down even though it accelerates reasonably quick.

It is my first diesel and I am used to petrol Automatices, Am I expecting a response that you dont get from diesels .

The kick down press button makes the car goes one gear down, if doesn't get enough speed at that actual gear and this makes rpm to go high.when you are at high speed and you go for a kick down press pedal the ecu calculates the need for gear down or not.
