I finally got around to replacing the SRS passenger seat recognition sensor the other day in our 2000 E320. For those of you who may encounter a problem with this sensor I can say having an extra set of hands made this job much easier. I tried to title this thread accordingly in case anyone else had the same problem and did a search.
I purchased the sensor from my local indie for $135, it fits under the leather seat cover and is truly a DIY job. So if anyone else ever encounters this problem and needs a few tips, I'll be more then happy to help them out.
Take care all,
Dale
