I like MB's just because they are ment to be worked on, and if you do a lot of work on them yourself you appreciate it. Change the timing belt on a Toyota, or work on a V6 powered FWD car where you have to jack up the engine to change the back three plugs.:rolleyes: Its like a vacation working on a MB after that.

The oil pan float should be pretty simple to change, it also is probably very cheap like $30. Again I am not that familer with the M119 but I find it hard to beleive that you have to drop the pan. Its probably stuck in the side of the pan with a clip and O ring, at least that would be my guess.

I havn't wrenched that much on the W140, but what I have done hasn't been any harder than on my W126. My favorite is the W210 its a fantastically great car to work on!

If it were my car I'd change the float on a Saturday and it would cost me all of $50 or whatever the float+ oil comes out to.

I'm told that you have to drop the oil pan out of the car to change it. That could entail a bit of work because on some cars (like my S420) you have to hoist the front of the engine a bit to get at the front three oil pan screws. Since you already have the motor lifted-up, you might as well do motor mounts too!:)

Well if thats the case it would be a bit of a PITA. Good chance to do the motor mounts though.

Oil level sender

Before any attempting to replace the sender, I would like to test it. Do you know in normal conditions, is it electrically open or closed to ground? I put the tester between the pin of the sender and ground and it shows no continuity.

With the wires from the float switch disconnected is the low oil light lit? If so ground the wire and see if it goes out then you will know..
