The lower more shiny metal box in the picture is it. A session with MB Star would likely point you in the right direction on those locks.

Thank you!

MB Star???

Star is the computer diagnostic tool used by MB. It can do about 1,000% more than a typical fault scan tool. It can look into every control module and do bi-directional control of its functions to confirm what is working and not. If it reports a certain sensor is not working properly (just as an example) it will not only indentify that specific sensor but a picture (similar as I posted for N93/1) and where it is located in the car. It also provides specific tests to confirm if the suspected reported issue is, in fact, at fault. It is the best way to work on a MB.

Wow! Thanks! It's also depressing because I really don't want to sink thousands of bucks into a car that's book value is, at most, $4500--and that's pushing it.

My W211 2003 E500 had similar problems with the battery dying every two days and it ended up being the power seat modules. My indy mechanic bypassed the circuit and soldered some wires together to avoid having to replace the modules. The power seats still worked but only with the ignition on.

Interesting possibility. I've been "hearing hoofbeats and not anticipating a zebra" but the cause may well be a "zebra" and not a "horse".

Exactly - doing a deep scan with Star will likely get you going in the correct direction. Then you decide what needs to be done and not be guessing. Nothing is straight up with these highly intergrated networked cars.

on my personal car...the bluetooth module will stay lit and active as long as its close enough to continue being connected to my phone after exiting and locking vehicle. when the bluetooth module is active, it keeps the audio system active as well.

not sure if this is faulty or by design.

YankTar

Pretty sure it's by design. My S500 is so old we originally had to buy a special phone to work with the electronics. When it aged out, M-B sold the V60 adapter that plugged into the phone slot and provided rudimentary Blue Tooth

I watched a video on Youtube that detailed this and it solved his problem. My problem is that the rear suspension goes down in spite of a new compressor and a new battery.

YankTar

That almost certainly means that there's either a leak in the rear suspension, or there's a problem with the rear suspension as well. Is OK once it's pumped up and you're driving?
I actually have the V60 adapter--I think I have 2 of them. Also the adapter for the SL55 AMG which is a little different. Been sitting in a drawer for many years now.

It is most likely a leaking rear air bags, most often when your rear air bags age, they develop tiny cracks in the rubber, and that is where the air is seeping out.
Or, it can be the air distribution block that is leaking, but you can spray soapy water and see if bubbles develop.
Most people just replace the air compressor, front air-struts and rear air bags, and they neglect to change out the air distribution block.
