E55 150K mile major maintenance summary ~$2K
Final cost: ~$1966 for parts. All labor was my own over three weekends (waiting on parts or tools). I could have done it cheaper but I'm working to replace parts *before* they fail. More cost up front, more piece of mind long term. The mirror motor was extra because the positioning mechanism was failing. Found a lower ball joint with a torn boot. With over 50K miles on the ball joints, I'll most likely just replace all four lower ball joints at one time rather than doing them one or two at a time.
The only task I did not accomplish was changing the oil in the front of the supercharger. When I went to do so, I could not find the nifty syringe with flexible tubing I had bought for this. Curses! Foiled again!
(EDIT 8 Sep 2018. Add to the list of things to remove/replace is the supercharger clutch pulley bearing. Mine failed 700 miles after I performed this service. I have the bearing on the shelf; I should have replaced it while I had everything apart. Now I have to tear into it again. Nachi 45BG07S5A1G-2DL.) Good DIY here: https://mbworld.org/forums/w211-amg/...g-install.html
I removed the fan shroud as I needed room to remove a stripped bolt on the tensioner pulley. Successful! Remove the metal piece over the radiator to ease this process. There are four "push pins" that are a PITA but must be removed to uninstall the metal piece.
Fuel pumps and filter replaced.
Before:
After:
Water pump was beginning to go. You can where the front seal was leaking coolant that was then running down the pump towards the lower radiator hose.
If you have the water pump out, now is the time to pull the alternator and replace the regulator and brushes. I was going to replace the bearings but did not have the proper tool to remove the front bearing.
I had to use an impact hammer to remove the two screws for the regulator; otherwise they would have stripped.
It was a rebuilt alternator on the car replaced during a dealer campaign so the alternator has between 106K and 150K miles on it. Minimum brush length is 5mm; my brushes measured at 8mm.
Another setback when I reassembled everything, pulled vacuum to vacuum fill the cooling system, and an o-ring on the heater valve failed (better now than on the road later). Remove the windshield wiper mechanism for easier access. A drum brake spring puller is perfect for pulling the metal catches open to remove the hoses. When installing the valve, I found it easier to pull open the catches on the new valve, use a small amount of KY jelly on the metal fittings on the firewall (and the plastic fitting on the hose leading from the engine) to prevent damage to the new o-rings, then press the valve on, press the catches, and pull on the valve to ensure it is in place.
List of tasks performed and associated parts cost. SBC shows estimated remaining life of 24%. Pretensioning reservoir is at minimum value of 72 Bar (72 to 102 Bar optimal) so I'm keeping an eye on it for future replacement.

By the way, if you cannot obtain KY jelly for the o-rings, Amazon carries this stuff that works just as well. Be sure to read the reviews to ensure it is what you need.

You don't need the syringe if you pull the SC to regrease the rear bearings. Keep a close eye on that 6203 RS. It's getting really hard to find good bearings with all the cheap ones on the market, and I think the S stands for stainless which has a much lower load rating. A good german or japanese bearing should cost 10-15 I would think.
Hey, if you do happen to have a good source for 6203 bearings, let me in on it please. I just built a big granite saw with 32 of them in it. I've bought 5 different kinds and I'm not impressed with the quality of any of them.

The Xike 6203-2RS I'm going to pull. I can find no technical data on rotational ratings, static load, or dynamic load. $16 for a four-pack. Digging into the reviews there were several comments about lack of customer satisfaction with the grease used in them.
I just ordered an NSK 6203-08VV (EDIT: order the 6203-VV, *not* the -08 as it has a much smaller bore. Back ordered so I ordered another NSK 6203-ZZC3)) with the same ratings as the ZZC3 above but with dual rubber seals and rated for continuous extreme conditions. Cost is $9 plus tax.
FWIW, I ordered all of the above on Amazon.
Fortunately, swapping the bearing is not hard. Takes longer to chill the bearing in the freezer and heat the pulley in the oven that it does for me to remove and install the idler pulleys.
Thanks for the "sanity check".

Now you have me re-evaluating my choice. The bearing I removed was an NSK 6203-ZZC3 rated at 17K rpm, 1079 lb-ft static load and 2179 lb-ft dynamic load. This is the one with the metal shields and not the rubber seals and I have since learned it is recommended for intermittent extreme conditions and not continuous extreme conditions. I paid $15 for it back in 2015. Upon removal, it looks fine after 60K miles of use.

I was going to say the price sounds way too low. But, then I realized you are doing all the work yourself!
I had the same service and it was well, a little more at an Indy. :-)

Go here and enter the bearing series (i.e. 60, 62, 63, etc) and it will provide the measurements for that series. If you enter "6203" it will provide the specs for only that item. Since this is JIS (Japanese Industrial Standard) all measurements will be metric.

Four hours labor (labor only, not parts!) to replace the water pump at the local Mercedes dealer comes to $660 USD plus tax. Parts and coolant are extra. I think I can remove belts and unbolt a water pump and install a new one for that price. Even if it takes me all day and I put in eight hours of labor, I come out ahead. Yeah, they have overhead, I don't. Still, the only way I can comfortably afford this car is to perform the work myself. Otherwise, I'm going for another Mazda....

Really good.
In the engine area, 150k seems to be the time by which the chains and guides (at least guides) need replacement.

My little ML320 has a very similar engine, (missing 2 cylinders of course) and it's tight and right at 330 thousand miles. I'm expecting similar life out of my CLS55 with regular oil changes. Hoping anyway. That little 6 cyl is a higher revving engine in daily use.

Got it. Anecdotes are great and they keep us warm and fuzzy on cold hard fact nights.
Chain guides need replacement at intervals around 150k.
Its great that you are not just just waiting for things to break.

Good info nonetheless and I wish I was aware of it sooner. At this time (primarily because I just don't have the heart to perform all of the above work over again) I do not plan on taking my engine down to replace the timing guides as it requires removing the front of the engine. To quote Sulaco from a different post, "Changing the guides requires removing the entire front of the engine: water pump, upper and lower timing covers, oil cooler, intake manifold, entire intake/ignition system, valve covers, and a few other odds and ends. My trusted shop is cutting me a deal at 1200 bucks but I can pretty much find a 5.4 engine for that much, so I'm torn." Post here: https://mbworld.org/forums/c36-amg-c...ml#post6527524
I would be open to replacing the guides and timing chain at 200,000 to 250,000 miles; plus would be a good opportunity to replace any rubber components on the engine (such as the o-ring under the oil filter housing).
I much appreciate the comments; I've still got a lot to learn.

Lovely detail on what you've done! I've just recently purchased a E55 on a 2003 plate that has been sat for the last 7 years, and want to go completely through it. I'm currently in the process of parting with some money by looking for parts for the old beast. I'm currently looking on auto doc for parts, but am thinking about going down the genuine route for the water bump and thermostat, and getting my belts and tenoners off auto doc. unless you know of a site that does oem parts at all. just after advice and recommendations on my build really. ive started a youtube series of me doing it up if anyones interested. heres a link

Autodoc isnt that well known on here I think, so you should be somewhere in the EU I also use Autodoc from time to time. I also still need to do the waterpump, but I wonder if aftermarket fits. I also did a lot of maintenance after buying my CLS55 and I documented it well, so feel free to check my thread.
Regarding belts, buy the Gates RPM for the supercharger and OE Gates for the serpentine belt. Tensioners are perfectly fine aftermarket.
I also just added you on Youtube

Bringing up a dead horse but my cls55 is approaching 121K. Im replacing the crank pulley and seal as preventive maintenance. Was also thinking of replacing water pump, thermostat, voltage regulator, rad hoses and maybe the radiator…. I currently do not have any issues with these items, but I think you and I have the same mindset of preventative Maintenance is key. . I see that you’re 05 has 225,000 miles on it. I would love to hear what all you’ve done to it since this post and at what mileage… debating on going with the changing of the fuel injectors, too, with the FCP Euro ones, brand new Bosch. I have a friend who basically has the same car as me, he's a car wizard and he said if it’s not broke, don’t fix it. I just know what it’s like to be on the side of the highway so I do believe preventive maintenance is key. I’d love to know what all you’ve done, and then, if there were some things that you wish you would’ve done while you were in there.

All four front control arms, rear air springs, fuel pumps and filter/regulator plus harness repair, o-ring between oil filter housing and block, recalibrated suspension, replaced headlights, replaced cap on coolant reservoir, flushed brake system, transmission fluid exchange and filter replacement, replaced supercharger idler double pulley ( metal pulley bore worn to the point a replacement bearing was too loose).
If I think of anything else, I'll add it to the thread.
