Maybe this guy just isn't used to a drive-by-wire throttle setup? He keeps mentioning the "cable adjustment" on his Bimmer. DBW throttle's don't have cables and ALWAYS have a tiny delay in throttle response due to the ECU checking things and issuing the command to the throttle actuator. Most people never notice. I'm not one of those people, I can tell when I drive a DBW vehicle (my Honda is a DBW throttle setup). It doesn't irritate me, but you have to have a reasonable expectation of how it's going to behave.

The W210 does have a cable between the pedal and the actuator. This was early in the days of DBW, and they basically used the pedal and cable assembly adapted from the 124 and routed it to a rotary sensor located near the brake booster under the hood. If I recall correctly the very first DBW from MB was the 400E in the early 90s, which was a 124 chassis. So when they were designing the W210 about this time it is totally plausible that they borrowed this assembly for the W210.
I think by the time they got to the 211 they integrated the sensor in the pedal. Our W164 shares a lot of systems with the 211 and this is how the pedal is set up on the ML320.
In any case the easiest way to check the operation of your pedal is with an advanced OBDII reader or a Bluetooth OBD dongle and Torque on an Android device. Call up the display for Throttle Angle on the screen and press the pedal with the engine off.
