LOL!
Hit 598,000 miles this evening. Car is running fantastic although it is running a little warm at lower speeds in our SoCal heatwave. Aux fans come on fine and I think the viscous fan clutch is operating correctly so it could be a tired radiator. Anyway, nothing serious at this point.
You can see I will be installing some new brake pads this weekend [emoji3]

Minor update...
The low coolant light came on suddenly a few days ago on my way to work. It happened as I was headed up a 2 mile grade on PCH headed into La Jolla. I was going along at a fairly good clip so I was a little concerned but I didn't see any steam and the engine temp was steady at normal so I didn't think I was actually low on coolant. Sure enough, when I checked in the parking structure, level was normal. Are coolant level sensors known to fail unexpectedly?
Anyway, I think it's a good time to replace the old reservoir anyway so I ordered a new one along with the sensor and new cap. Should be here in a day or two.

Ya, it's probably just old. I've been wanting to replace the reservoir so this is a good excuse to do it
Usually what happens is that the plastic housing that contains the reed switch starts to leak and coolant gets inside of it. Usually all you have to do is replace the sensor, and you're fine.
However, if the coolant has actually started to permeate through to the outside of the sensor, it then tends to enter the interface of the male/female terminals at the connector plug and they will often be corroded to the point of uselessness.
Replacing the plug housing and soldering on a couple of new female sockets is easy. I'd give you the part numbers, but I am not in a position to get them at the moment.

And yes, sometimes the float itself gets permeated with coolant, whereupon it then becomes a "sink" instead of a "float"...

Thanks Klink. The socket and terminals are fine so it's all internal. I should be receiving new parts from MB Gainesville on Friday. I also sourced some braided hose for the overflow tank that matches the OE hose perfectly at a fraction of the cost
Glen,
I have the same problem. Light comes on partially sometimes. I have a new Hella sensor somewhere out in the "Black Hole" I call a garage. I have been looking for it for months.
PS; With my wife's "STUFF" encroaching on to my side, the garage looks like Dagwood's closet.
Hey Young People!! Pay attention that's a comic strip "Dagwood & Blondie"

As noted above the sensor is probably bad. I've had to replace a couple of these. Only use OE or Hella (OEM) sensors!! And, only use the OE/dealer seal ring, it is a different material than the O-ring supplied with aftermarket (Hella) sensor.
I generally replace the coolant reservoir as preventive maintenance, along with a new sensor + O-ring, new cap, and coolant flush. If the reservoir is more than ~10 years old, I'd do the full Monty.

LOL. Here is the hose I purchased. http://www.partsklassik.com/p-258-75mm-cloth-braided-fuel-hose.aspx?keyword=2122.0600
This is used between the reservoir and overflow tank in the fender.
NICE! Pretty sure I haven't been able to find this with the correct braided cover... thanks a lot Glen, I'm about to be poorer!
Hey I just got off the phone with this store. They also have the ability to manufacture to own spec the crimped fuel lines and any other applications for our cars, and the w126 (and others). They sell and or fabricate anything we would need along the lines of hoses and specific fittings...(brake lines)
X 1,000,000 (kilometers!)
MB seems to recognize 1,000,000km at the 625,000 mile mark...at least that's the number on the badge form. I'm currently driving about 13,000 a year so it should be right about this time in 2017
It's another hot SoCal day but I decided to install the new reservoir tank...the low coolant light on the dash was getting annoying!
Here are the new parts:
Here are a couple pix of the old parts in and out of the car:
And the new parts installed:
The old braided hose was hard as a rock and brittle so I'm really happy to have found an OE-look replacement. I bought enough to do my silver car too since I couldn't find the right aftermarket hose when I did the reservoir on it a couple years ago.
And lastly, here's a picture with the warning light off [emoji106]

is that a pickup line ?

Thanks Klink. I run 50/50 usually and sometimes even a bit "thinner", maybe 55 water/45 G-05.
When I lived in Sacramento where it was rare to get anywhere close to freezing, I used an 20/80 mix (20% antifreeze, 80% distilled water). Plus a bottle of Water Wetter.
Even a 33% mix will protect down to 0°F. Not much need for a full 50/50 unless you live somewhere REALLY cold, or expect the possibility of temps going below 0°F (i.e., maybe driving the car to the ski resort in winter). Very few cars in USA actually experience temps colder than -34°F which is what 50/50 protects to.
Hi Glen
I have been good and putting mileage on my E55
(now 160k). Thanks for all the work you are doing - now there is little left except the engine block that is original! It is SO cool to see her fixed up again! 
Can't wait for the 600k picture! And then the 625k! Drive safely!Martin
Well, today was the day the high miler crossed 600,000 miles. Nothing else to report, the car continues to run well, even the transmission is shifting great, with a slow to engage reverse the only real symptom of the high mileage. I honestly wouldn't hesitate to drive this car anywhere!
And here's a video of the last mile. Apologies for the shakes. Enjoy! [emoji3]

Today marks exactly 3 years that I've owned this car. I picked it up from DrP's home on Monday January 21, 2013. It's hard to believe how fast the time has gone by. I've gone through quite a bit to get the car where it is and still have a ways to go but it's been a fun and rewarding experience.
Running update: Nothing really to report since crossing 600,000 miles other than the fact that I'm using the car quite a bit less at the moment as it's become my wife's main car. It continues to run well as a daily driver/do anything/everything car.
Some stats:
As of 1/14/16, total miles: 601,676 (22,531 since I acquired)
1329 gallons of fuel consumed at a total cost of $4653
Overall average MPG: 17.2
