Minor clunk/jerk when taking off from a stop




Basically I've learned to let go the brakes pedal before depressing the accelerator.

As I said, I hardly notice the KID activating on my car now. Of course, this is after updating the software, resetting the engine/transmission adaptations and servicing the transmission (fluid/filter change) over the course of my ownership. The pronounced bump/jolt when stopped in gear, is now just barely perceptible (to me).
The KID "feature" can be disabled, but this is not something a regular dealer tech would be allowed or able to do (and I can't see MBUSA having someone from engineering design/load modified coding on a car outside of warranty to disable a feature that is not exhibiting a critical or safety issue). As JettaRed said, you would need to find a remote programmer which would entail renting or building/purchasing a diagnostic system with the necessary software.
Schedule an appointment with your local dealer to have them ascertain if your issue is due to the 7G NAG2 transmissions activation/deactivation of the power-free or neutral state (KID) feature when in drive and stopped. If so, the bulletin calls for updating the transmission software and/or removing the driveshaft and greasing the splines.
I have a similar issue with my E250 BlueTEC 4Matic, only the jolt, jerk, lurch or bump occurs about 5 seconds after coming to a complete stop. The jolt is usually barely perceptible, but on occasion has felt like the car behind me has tapped my rear bumper. I only recently came across the bulletin, so have not had a chance to follow up.

I wonder if KID might be a German acronym.
