Accelerator Speed Sensor?
Let me beat the wisecracks to the punch: "It senses accelerator speed."
I've done a search here (and a couple of other places) and cannot find anything on it.
I took it in and suggested that it was the intercooler pump
(see, https://mbworld.org/forums/showthread.php?t=113521), but when tested, the car threw out a code indicating that the problem was the "accelerator speed sensor."
I'll post the information when I get the invoice (on the off-chance that anyone cares, or that the issue might come up in the future for someone else).
