Do We Rely On Benz? Well, Here Are The Most Reliable Mercedes-Benz Engines Ever Built

- We look at the most popular Mercedes engines and give you the most and least reliable of the bunch.
In 1982, Mercedes-Benz unleashed its most reliable car ever, the 190E. The 190E resulted from Diamler's £600 million project to produce the bulletproof W201 and set the foundations for the W124. The 190E became the C-Class we know and love today, while the W124 was renamed the E-Class in the early '90s. Mercedes-Benz of the '70s and '80s regularly touted the phrase 'over-engineered' when marketing their products. A Greek taxi driver, Gregorios Sachinidis, proved this by taking his 1976 Mercedes-Benz 240D over 2.8 million miles.
However, today a Mercedes-Benz product has a 35.87% chance of requiring major repairs during its first ten years of service; this places them average among fellow luxury car brands. Adding further fuel to the fire is maintenance costs. For example, a product from Daimler will cost consumers around $15,986 during its first ten years in action, regarding maintenance and repairs.
Compare that to luxury industry leaders Lexus, who average $7,786 to maintain one of their products over the same period. Let's look at the best and worse power plants housed within a Mercedes-Benz engine bay to explain their fluctuating reputation.

OM642 is not an emissions nightmare, also it is a great engine and can do 1 million miles . It has to be maintained well
So you got the answer - maintained well. Good engine should work fine without any extra care, oil service and go back on the road. Om642 are great and terrible equally. Some of them drives hundred of thousands kilometers without any problems and some are seized without any extra reason (even those which are well maintained) at 200k (many of 231 Hp).
They are not Good at all
I have 3 engines cls w219 Ml w164 and sprinter w906
Om642 they need good maintained
Injectors problems turbo , manifold
And the only oil that the engine likes is Shell 0w30
@@GCRTeamPortugal well i like it mine it has over 400k on it and still doing just fine
@@jon3mi3s well good luck 🙏🏽🙏🏽
@@GCRTeamPortugal 2005 280 v6. whats that engine.
M273 is a beast of an engine. I’ve owned 3 (5.5L) and have never had a hint of problems with them. Still currently own 1 (E550). I’ve had problems with the air suspension, but engine and drivetrain have always been solid.
M113 and M112 are legendary for reliability ,,yet they get no mention here ?
I have an SLK320 with an M112 and I think it's fabulous.
You are absolutly right, these were the best petrol engines by far. I ha d several of them, no problems at all.
@@oliverm.7928 Thanks , I have both , M112 and M113 ,,,great engines.
The M112 was the most reliable gasoline 6 cylinder, but I think the M119 was the best V8 overall. The M113 and M119 are equally reliable, however the M119 naturally makes more power with less displacement, and is basically just as efficient. The M113’s variable intake runners and twin spark design were implemented just to “come close” to the standards of the M119, but it still falls short. Both engines feel very similar in everyday driving, but the M119 is FAR more capable higher in the rev range thanks to its 4 valve design, vs the M113’s 3 valve design. You can easily take notice of the fact that Mercedes never produced a 3 valve engine again after the M112 + M113 engine family ceased production. The technology was nothing new and Mercedes didn’t originally invent it… rather it was copied from 1980’s Japanese engine technology. (Twin spark, 3 valve, SOHC)
Yes for some reason when they first appeared (maybe because of the great M119..) they weren't well regarded but have proved themselves excellent. Rear main seal leaks are about the most troublesome thing!
Excellent video, I'm a Benz fan for like decade and I've owned OM646 and now I'm owning OM605.
I own an OM606 NA engine car. This engine is indestructible!
the om651 is a great engine have seen many past 500.000 km
I’ve got this engine with a 722.6 transmission, 2008 c220 cdi w204. At 170kkm right now, will I get there?
@@marvinwilliams7938 oh yes you will
2:08
Its worth to mention that the M103 was made in two sizes. 2.6l and 3.0l.
As mentioned in the video it made 166hp. But thats with 2.6l.
The 3.0 made 188hp with 260Nm = 192 ft lb of torque.
I own 2 cars with M272 engines, W221 S350 + W164 ML350, the ML reached 300K+ mileage with 0 issues, not even the most rumor about the failed timing chain. I know.. when you source your info based on some issues in a number of factory reclaled 2006s engings not even all 2006 😅.. But the M272 was continue in production for almost 10 years 🧐 which say somthing about this rumors about it by Toyota Fans 😂!
Rev up your engines! Lol 😆 I had to say that after you said, Toyota
unfortunately my m273 giving me some timing issues at 150K miles, might just be the sprocket as everything else outside of the timing chain has been looked after even oil changes of course. The engine serial number falls into the range of defective idler gear sprocket, or in your case, the balance shaft sprocket, were those replaced on yours??
@@saudal-barrak5672 This video was entirely made by ai btw...
But the early years of the M272 and M273 both had timing chain issues. I have a 2011 E550 with the M273 and it runs great at 180k.
I have an early m272, no issues too, and a 651913, that needs only longer drives, and a sporty driver. Near 400k,and no problem.
@@MadBuddhaAbuser What about an M272 from a 2012 car, i'm looking into geting one...?
Hi im newbie, is the mercedes e300 diesel turbo bluetec is all right kind of engine? Or id have to avoid in 2024?
What about the OM646? It makes even with bad maintenance 400k km and with good one until the million.
the OM651 is used in about all mercedes sprinters and used ones have 200k up to 300k miles on them and still run fine.
Their unreliability is not within these engines but due to them being misused by the sprinter jockeys flying off immediately upon cold start.
I’ve got the om651 with 722.6 transmission , 2008 c220 cdi w204. Currently at 170kkm, will I hit 500kkm?
Never had a problem with the M273 ... it's a great engine with a good performance
The M100, the original 6.3 V8 was a strong running beast
the 616 isnt mentioned which sucks, in fact the 616 is way robust and tougher than the 617.. the issue with 617 turbo is that it can easily throw a rod if not properly maintained oil wise and having to worry about a an extra cylinder AND oil leaking into the turbo if its not rebuilt... the issue with 617 non turbo is that you have to be very careful when driving over 60 mph as in putting GOOD quality oil and the first cylinder has a perplexity to starve from oil as well.. the 616 is as simple as it gets... i daily a somewhat rusty 240D EVERYDAY and it has yet to fail me as im on top of every little fix it needs... keeps up with traffic perfectly, although i refuse to let the transmission start from first gear since its super slow when accelerating but fast when it gets up to speed..
Some minor mis information but good video 👍🏼
I drive a 2003 c230 with the M271 (1.8) 234 thousand miles going strong!
Driving w211 E200K 2003 too with 314k on clock and no issues outside the transmission that needed solenoid replacement. Easy task even for newbies!
I have a W124 with the M103 2.6 - it has run well for almost 500.000 km's in 34 years, and still going strong. I bought a second hand engine for years back, but it seems like that was a waste of money and space in the workshop, as the one in the car just keeps going... and going... and going...
Are you nuts? 2.1 /2.2 diesel are bulletproof. They can run forever, in Europe they are known for how good they are
I had a w123 with fhe 5 cylinder 3.0 diesel, very reliable until my timing chain tensioner fail at 130mph, that was the las time saw that engine running😅. Then I had a w220 with the m113 and literally not a single problem even treating it very bad with the maintenance and my driving... I sell it with 280k miles, running like Switch watch. Currently I'm driving a w209 with the om642 v6 and the only problem I've got was the turbo actuator that i change myself in half an hour for 80bucks and a few fuel hoses that needed replacement for the rest the engine is a beast it pulls like a rocket without any fuel consumption, it has great mpg idk if it is because of fhe 7g but great car overall with 200k plus milles on the clock.
OM 61X series, in general and the OM 616 in particular. Also the M110 six cylinder. Also the 4 cylinder gas engines in the W123 range. They are common everywhere on earth except the USA which unfortunately never had them.
What’s about the 2.2 CDI ??? The one that came with the W210s ?
My man what a shitty list. Here, have some corrections:
- OM617 came in the 300D from '74 until '85, and in the military Hagglund until '91
- The M111 had NOTHING to do with the OM617 as it was a gas engine while the OM617 was a diesel engine. The M111 was made to replace the M102 engine.
- The M111 isnt among the most reliable engines Mercedes has made due to the intake camshaft snapping upon tensioner failure and the problematic injection systems it came with: PMS and HFM.
- The OM606 engine in its stock form is an absolute garbage engine in terms of reliability. It is a brutal powerhouse when properly modified though.
- When the OM603 is mentioned, the picture shown is of an OM601, 4 cylinder (pretty much the same anyways).
- The M116 pre-1984 had timing chain problems
- The M116 never came in the W124 chassis as suggested in the pictures
- The M116 had its bigger brother M117 which came up to 5.5L displacement and is much preferred by the comunity due to its significantly higher power
- M272 engines had the balance shaft reliability issues fixed in 2009 and beyond, thus making them pretty reliable engines, same with the M273.
yeah doesnt seem to know the difference in the prefixes
Thank you for your factual input. Concerning the M273, after tons of research I discovered the repair was done in 2008, and cars with engine serial numbers which are higher than #2739...30088611 have the proper chain cog.
The om606 is not reliable in stock? Are you sure about that? That contradicts quite much the fact that it can be modified to 450 HP solely with a bigger pump and a turbo. The internals and the block takes it easily. Maybe it's just slow AF in stock?
@@SpagettyCraft It is definitely not reliable stock, the EDC pump and ECU are garbage, the plastic fuel lines are even worse, not to mention that the intake camshaft gear slips as its only pressed on.
Fuel heater, EGR, vacuum controlled wastegate, the list goes on.
Once its modified and all those dumb details are fixed, it is indeed reliable, but it loses the "stock" title, doesnt it.
I own a 606 superturbo in my W124 making 400 hp, so I know what im talking about.
@@user-gv7ne5fq5i Well, my neighbour has an OM603, I thought there's not much difference in them, since both are legendary. His one has around 600000km, clean and dry, needed some spark plugs last year. I also have a friend, who had like 30 mercs with either om606 or om603, most of them W210 and he says that it's reliable as fuck. Those small things you mentioned are just nuisances, and don't cost much. I don't think they need replacement every year either, so I wouldn't call the engine unreliable because of that.
My M272 was a nightmare. I almost quit ever buying a Mercedes again until i discovered the M276. The 3.5 liter version is just too good to be true. Bulletproof and fun to drive.
My favourites are the om648 the om606 and the m275
How bout the m113 ?
Exactly - Just bought one - Peachy.
arguably the most reliable and powerful European v8 of its era
The M112 and M113 and their kompressor siblings are undoubtedly the best
It really should have been the M119..
You forgot to mention the OM646.
I have to disagree here. Late year M272 and M273 are just superb engines with no major flaws. OM642 is one of the best engines ever, it has some oil leaks but other than that it's just a powerful and relaible beast.
Which one is better and more reliable - CGI M471 or CDI OM651 on C-Class w204 facelift?
Om651 look for milage and proper replacement of the timingchain or u will run in some few problems. Beyond that it is a very solid engine. I had a c250cdi with 4 matic a few years and it was splendid!
I would only choose facelift with the om651. The early models had too many problems. The small petrol engines had timing chain problems also.
@@nikolaitinen4509 thanks mate
The om606 im sure a f1 guy designed that engine. A 3L diesel that can be tuned to 600hp in the 90s
How about the OM612?
well i have it on my C class ( w203 ) and i can say the engine need only diesel

Ive recently bought a 2009 2.1 c220 cdi sport,can anyone tell me if them engines are any good????
Is it om651 or om646? The 646 is very reliable. The injector seals needs to be replaced once in a while. The om651 had timing chain issues till 2012-13. And early ones also had injector problems but they were covered by warranty almost all. Om651 also leaks coolant from fuel filter bracket and oil filter housing also leaks oil or coolant, but those arent hard to fix.
I’ve got an early om651 722.6 transmission c220 cdi, 2008 w204. I heard these ones don’t have timing chains, is it true? Wondering if I can hit 500kkm
Both 646 and 651 are with timing chains. You may have to replace the chain before 500k. It really depends how you drive it.
@@nikolaitinen4509 Just regular suburban driving I'm not too hectic with it, hopefully it'll achieve it, still havn't had the issue yet
If it rattles on coldstart then you want to change it. How many kilometers you have now? Maybe it is already changed?
Disagree regarding the M272. Am a second owner of 9 years (W211 E350, 2005). Have replaced the intake manifold (tumble flap) and thermostat. The ‘big issue’ is the balance shaft drive cog which I haven’t experienced-about 20% of affected VINs will fail due to a badly annealed or tempered balance shaft drive cog-necessitating expensive engine removal to repair. The vehicle itself, at nearly 20 years old, is in excellent condition. So even if the cog needed replacement, this is still a lot cheaper than replacing the car.
Replacing cog means replacing whole balancing shaft, and probably whole timing mechanism. It could cost more than car value.
@@luki1503 I understand your point - my point is the remaining car is in such magnificent condition that I’m prepared to spend $10,000 on the balance shaft job-and then enjoy a brilliant machine for another 20 years :-) Much cheaper for me than buying another car and better for the planet too.
so what is wrong with the m273?
It's their most reliable engine in my book anything 2008+
@@abelbenzohey man I am thinking about buying facelift w211 with the m273 and 4x4 7g tronic anything I should look for or worry about cuz i read the the m113 and m273 are very good and lasting engines
@@user-ts4rh7lz8e The 4matic will probably give you more problems than the engine itself with CV boots tearing and I've also seen the front prop shaft breaking while driving and taking out the catalytic and steering rack, in severe cases it can take out the oil pan and damage the transmission case, engine mounts require a lot more labor as well. But if you get rear drive the most common things to worry about is oil filter housing leaks, not as labor intensive as some other engines and might be a good time to do belt, tensioner and pulleys if hasn't been done; oil separator cover, easy fix; cam magnet solenoids 4x, thermostat, power steering pump reservoir; all relatively easy repairs. Don't forget about the airmatic, the ride is amazing but you'll have to address at least the front struts at some point, and maybe the compressor, and valve block.

W221 m273 5.5 ; 2010 y. - 200 t. Miles - any problems
m271 1.8l s.c. ?
1.8 M271 is not that bad, it has a few issues of course but everything is easy to fix and it just needs maintence as any other engine.
My MB has the M273. My car is the r230 SL550. How reliable is that?
After mid-2008 (after July) they have fixed everything relating to that engine's reliability, making it a pretty bullet-proof engine similar to the M113. It is even better cause of its gas distribution, variable valve timing, horsepower and MPG, I get better MPG than the 306 hp older model. I have the MB W219 CLS 550 2008.
@@Doctor-Fate yeah this video says the m273 is one of the mb motors to avoid, but my SL550 has actually been the most reliable car I’ve ever had. And the motor feels as strong and stout as ever after so much driving. And I’ve owned Japanese cars like Infinitis too in the past. My SL550 is a 2009 year model btw.
@@timothydowd4180 They give the m273 a bad rep cause of its initial modes 2006-2007, cause they had big issues. The ones afterward are good, dont worry, you got a pretty good one, just take care of it with regular maintenance and dont go for cheap replacements. Cheap always comes expensive later. SL550 damn good looking beast, hope you continue to enjoy it fam 💪
@@Doctor-Fate Thanks. Yes, the car has a beastly V8 sound I love yet still refined compared to say a Corvette which I also had before. SL550 is a far better car than a 2010 C6 Corvette btw. And From what I have experienced in all of the other cars I have owned, I have had 8 cars in my past total, the most engine and reliability trouble is on small displacement turbo charged cars. The most reliable stout workhorse motors seem to be naturally aspirated big motors like in the SL550… a 5.5 liter is a large motor. I also prefer the driving characteristics of big NA motors over peaky turbos any day… and the V8s make the best sounds of any cars imo. A used r230 SL550 is an incredible value in the used car market thanks to the magic of depreciation.
Om611, is legend.
Oh wait.. I see the m273 which I have is an engine to avoid… but I’ve driven many, many miles in my SL550 and had zero issues… it seems like a stout v8.
So basically buy a Mercedes before 2010
Before 2000. Except for the ones with wiring harness issues from 94 to 99 or thereabouts. Or the 80 - 83 3.8 liter V8 with the single row chain.
M271❤
Forgot the om648😢
M116 was the wrong engine to choose.
The bigger brother M117 5,0 and 5,5l was the best in the W126 series.( + more power)
M116 tend to have timing chain stretching much, much sooner then on M117.
what problem the M271?
I have a c230 with the m271 supercharged engine and engine gave out with 75,000 miles on it lost compression in cylinders. Ive seen many cars with this engine for sale with high mileage close to 200,000 sucks this engine gave out I’ve replaced it with another m271 no issues so far.This engine better make it to 200,000 miles
My OM651.930 engine is 120k without any issues
autos with big engine cc, year tax more money, in few countries
120k is nothing
M271 is also not bad (1.8 L compressor)
M273 isn't bad actually. The M272 is much worse.
I agree bre my parents own an 07 gl450 with an M273 and kept it for 13 years never broke down
I’ve heard that early w211 e550s are not reliable but if you get a 2009-2012 e550 with the m273 they’re pretty darn robust. I own a 2010 e550 with just over 100k and it’s been very reliable. Just an evap leak and rain/light sensor in the past 5k miles which is not the engines fault
There literally the same engine just with 2 cylinders less or more😂 both engines inherit the same problems
@@fakenews3676 true, but since the m272 has 2 less cylinders, it has balancing shafts to keep the engine balanced and thats where the the failure point is. the m273 has some flaws too but is a way more reliable engine
@@eliazansou995the m272 doesnt have balancing shaftS, but only ONE balancing shaft. The Problem isnt the balancing shaft but the balancing shaft sprocket. Thats why the m273 has similar Problems: It has the Same sprocket although it hasnt a balancing shaft.
M112 V6 is sadly ignored. As robust as the average OM (diesel) engines cheered here.
M120 entered chat
M272 3.0 how was it?
There is an issue with the early production of this engine. Due to its specific angle between the blocks (60°) the engine needs a balance shaft(spinning counter the direction of the crankshaft, driven by the chain for the camshafts. The gear wheel of the balance shaft used to be worn very quickly(even after 50-60k km). The affected engines are from the beginning of the production(2004) until the late 2006 production series. However Mercedes did a big and free service campaign to solve this. I advise you to avoid a vehicle produced before 2007. After that all engines are produced with straightened gear wheels. Another pointed issue is about the fragile plastic intake manifold claps. But this is due to poor maintenance. The engine has an oil separator which has to be replaced regularly(not expensive, about 30-40$). Otherwise the oil passes through and reaches the plastic caps and ruins them. Another pointed issue are scratches on the cylinder walls but this issue corespondes very much with the fuel quality and it is reported mainly from Russian market(Lukoil😂😂😂). In conclusion if you properly maintain it you receive an exceptionally smooth running engine with good mileage and nice throttle response even though the engine is naturally aspirated.
M111 was super reliable until I pumped too much boost into it 🤣🤣🤣
OM601/602/603 is the same engine, just more cylinders.
those autos which has big engine cc, year tax more money, in few countries

M112 sirrrrrr
W204 and W205?
Give me a CJ 5/7 with an inline 6 but still bad ass!
0m 642 is a great engine fool, like every engine they need routine maintenance. Mines already got 300k on it and still shits all over many newer engines.
My ml350 engine is running like a Lexus
M113 and M113K are THE best V8 in mercedes history
So I have a 2010 s550 4matic with the 273 v8 and I have over 185k miles. Never a problem. I do 5k oil changes and 40k transmission flush. The engine runsike a top. So I have to disagree with this part of the video. Maybe the early production engines had some issues and maybe they fixed all of them by 2010. Same thing goes for the M156... The earlier ones had issues but got ironed out a couple years later.

I have the M271 1.8L with almost 500k km so I don’t know how true is this 🤷🏽♂️.

om606 is "not quite a performance engine" 🤣 buddy...
Where is m113?
Also m111 is more reliable than m271
The 603 was a looser .
Any Corolla engine will put all Benz engines to shame!
You just put your ignorance on display for all. Corolla really?
Only concerning cost of maintenance/repair. Toyota/Honda engines are built cheaply and simple, designed to be disposed of when worn out because the cars they’re in are near worthless anyway. Mercedes engines are designed to be infinitely serviceable/repairable, because the vehicles themselves last a lifetime.
Lots of facts and pictures scrambled arround by AI, wasted time for a Mercedes entusiast!
Why you use FAKE AI voice? You have your voice too.
M273 is a fantastic engine after the balance shaft issue and a couple other issues were fixed. Video sucks
Agreed. Thr only issue on m273 is the 2007 model with idle gear and chain issues. Rest are reliable specially the facelift 2010-2011. Only issue I had in mine was squeaking belt due to oil cooler that I need to get fixed but I'm doing it later when I have a lift to do the rest and engine mounts.
no balance shaft on the M273 only idle gear. Mine has 121M kms and runs as smooth as brand new. Treat your M273 well and it'll treat you well. These engines require regular maintenance to last long.
inaccurate
This channel is bs, ai generated
This is a heavily flawed, exaggerated and inaccurate list of engines to be named “most reliable.” Proper research should have been performed before making this video…
You mad?
@@B501R No, just disappointed.
how about the m104
In its stock form its pretty problematic as most (if not all) M104 came with biodegradable harnesses, and their ECUs are notorious for burning out transistors. Also, the HFM-SFI system itself is quite crap. Stick a standalone ECU in it and problem solved.
I have an s320 and it's been with me since 2019 and so far the only issues were the water pump and the throttle body.@@user-gv7ne5fq5i

M104 bulletproof engine
After replacing the headgasket and wiring harness on our m104 at 100,000 miles we have gone another 250,000 without any issues. And the best part about the m104 is that after 30 plus years, it still pulls strong and idles smooth as glass
