roas, on the 500E, the EACM is one of the electronics modules that are in the weather-tight box that is located where the battery is on a "normal" W124 chassis - in the corner near the firewall on the passenger side of the engine compartment. It is something like a $2,200 part, from what I've read so far. I'll return to my dealer on Monday with supporting material to determine if there was in fact a recall on that part. So far, they say "no."
