1998 E320 "Oil Sensor Defective"
 

The warning "oil sensor defective" is showing up on my instrument display cluster. I udnerstand that the lower oil pan has to be removed. How much labor should I expect form the dealer for this and is this possibly a DIY job? Has anyone done this, any hints?

Thanks,
Chris

I have a 93, so I'm not sure configuration-wise how much effort is needed to replace.

I suspect it could be a DIY...drain the oil and undo the pan bolts to remove the pan. That would allow access to the oil level sender.

But I would not rule out a problem with the harness attached to the sender. You are not plagued with the harness problems of the W124-series, but even with the main engine harness replaced in mine, I inspected some ancillary harnesses and discovered severe deterioration...one particulary bad harness eventually caused my oil pressure sensor to fail...:(
