I have recently join the MB club and purchased a used 2016 (W212) E550 (M278) 4matic and had several questions. I noticed the temperature gauge to be sitting between the 90C and 100c as I know that the temp should be between 80C - 90C, however when checking my obd reading it would show the engine coolant temp when ideling (after somewhat a rough drive and 8c outside) to be between 95C -105C. Now would that be normal for this M278? I attaches a picture of where the gauge is. 136K on it and coolant is full. Thanks!!
That is where mine sits, and I just got completely redone (Water pump, turbo hoses, radiator, thermostat, aux water pump). 2016 would be a Canadian car, so the cooling does not get abused as much as down here in Florida.

oh thats a relief! When did you have those repairs done? And what was the approx cost? Just so I know when and what to expect.
Dash gauge is dummy gauge, so get a scanner to see what it really does.
Different engines, have different thermostat settings, but most of them open in 80's C.
100 is slight overheating, so check your whole system
Temp should be between 95c and 105c. The temp is read in the block with a temp sensor in the front, at least on the M278/M157 IIRC. He is at 8c temp outside, which will tell the ECU to command the thermostat to stay close for longer to keep the engine hotter.
This was very helpful, because yea, I did use a cheap OBD2 reader and at one point it started reading 105C - 107C (after pushing it hard and then idling) and that's when I heard the fan kick in on low speed and the temp began to drop to 100C, but in the back of my head I thought oh **** its supposed to be between 80C - 90C always. Glad to know that is normal and cooling doesn't kick in until 105C
Surya, Juan, Pierre, Chassis, Kajtek, MrK, LCG,... wrench-geeks: this is EXACTLY the sort of in-depth information I tried to INDEX by creating a "Bible thread" recently (index of links).
Excellent stuff is buried all over this forum... not easy even for anyone of us to find precious info.
What do you think: useful or useless to create LINK INDEX??

I find the sticky section of the W212 forum a bit skinny. Adding such index as a sticky will be the entry point, and then a lot easier to filter by newcomers or us to grab a link for new threads

Go to W210 section on benzworld.org and see index of topics done in 2 ways.
The section was very fortunate to have highly-educated members, who have done excellent work. Bad part, everybody is moving ahead sooner or later and new owners of aging MB present different level.

Yes, this is it !!!
That's what I am talking about, thank you Kajtek for sharing this example.
I have created a link for this W210 power users...
A header post with an index of links pointing to key threads plus the key threads where the content is developed.
Individual can elect to index all sorts of things they are interested in .... wheels, airmatic, tuneups, modules, fixes...
Keeping things disorganized is a giant waste of ressources.
I prefer curmudgeon, but old fart fits. great work you guys, I plan on keeping my '12 for at least ten more years, just turned 32k miles and if I can get to the desert soon, I know it will make it, so I will be looking back on all this awesome work on the 212 encyclopedia for quite some time, My '13 is about to turn 90k miles this summer and has been in the salt for ten years now, I went and saw the '23 E and it's really nice, much nicer than the 213, so we'll see...
I run into new E at cassino and it is impressive. Much better than previous body.
What year they start?
Would they be available in US with OM654 diesel, I would start saving money.
I am still missing hood star on it.
I agree! way nicer, the styling on the outside is way better, interior is also, I was hoping to find a 5k mile car in '21 or '22 so I went down to my brother's place and drove a few, yuck. I even drove the new for '22 C class, which I thought was nicer than the 213. it's only one inch less in width and three inches shorter, but you could feel the difference in the ride comfort, not a lot but yes, still C class. They both had the same four cylinder turbo, but it seemed a little quieter in the E, shifts seemed a little more refined also, but again, not by much. They now come in premium, exclusive and pinnacle trim, I drove an exclusive, so not loaded but not stripped either, the C was new for '22, the E was new for '23. I drove an E350 4matic. in my opinion, not as fast as my '13 and louder during acceleration, if price was not too important,I would like to drive the E 450 with the V6 first, to see if I could live with the 4 cylinder, also with Mercedes or I guess most cars, first year production tends to have more issues, most of which are worked out by the second year, so there's that concern. the digital dash was really awesome. I did not specifically inquire as to a diesel option, but I didn't see that option at least for the US in the brochure. Lots of hard decisions!

Pierre let me help you make it easier for you, I would not touch an MB 4-cylinder gasoline engine produced in the last 10 years. Let us review their track record:
M111 - 1992->2003 (11 years run)
M271 - 2002->2015 (13 years run)
M274 - 2011-> Present (12 year run) and a piece of junk with wrist pin issue, broken piston, etc. Lawsuit in progress.
M264 - 2018-> Present (6 years run) transition engine towards electrification from M274->M254->xxx. Casually came out around when all the issues of the M274 started to pop up worldwide.
M254 - 2020 -> Present (3 years run) includes electrification with a 48V battery. Hope you have read the horror stories with the initial 48V vehicles.
It seems to me MB is sending out technology-in-progress engines, and customers are their QA department and supporting ($$$) the transition. Would we be able to find parts for the engine with a short run? Will the independent be able to learn enough on how to fix these engines since there will not be many of them out there.
I would stick for the established V6/V8 generations, though not perfect until the recent versions stabilize a bit more.
*** Updated *** to be fair with the diesel engines .
Damn, I missed the 48 volt battery thing entirely, pretty sure this was the M254 in both the C and E, so I guess that leaves me with the E450, additional 12k on the price and a 3 liter turbo, bringing the sticker to almost 80k with a few amenities. I was hoping to skip the turbo, but that is no longer possible, damn. Maybe I'll have to look towards the AMG C class? The ride is already compromised from the E, imagine it just gets worse in the AMG and I'm 64 now, could use the extra inch in seat height, I already notice the difference between my sport and luxury 212's. Good advice, thanks Juan!
They all had facelift mid life.
I owned./Own 1 to 4, Shall I shoot for 5 ?
The W123 and W124 was at the time classify as 300 class, before MB come with letters for body description
Actually last years of W124 were called E class, so that would be the 1st
I was gonna ask what we W212 Owners think about the new W214 but anyway it seems E Class ,as many other models, are getting longer . To me , W212 still holds the better proportions over W213 and W214 .But hey , sorry op for veering off the main subject

They were officially E class, just as a suffix at the time. Similar to SL, SEL, SEC, etc.
BenzV12, I agree, that's why this is so hard!, Juan, my first new Benz was a 190E, '91, had it until replaced with a E320 in '02. Then E350 '07, on to E350 '12. Wife's first Benz was '93 300 SE, then S500 '03, then S550 '07, Now she drives the '13 almost AMG Sport, seems Kajtek has me beat though!! I also had some toys as well, A '01 SL500 and an '06 SLK 320
