Every 6 years or 60,000 miles we have to replace the spark plugs of our Mercedes, that's requiring of Mercedes maintenance booklet. So let's replace the spark plugs for my six years E350 (M276).
In the MB repair booklet, there is a step to remove the intake manifold, in order to remove the ignition coil easily. But that must replace the intake plenum gasket, that'd spend another a hundred bucks and more time. So follow this video, you might save that bucks and time to replace all of six spark plugs.

奔驰的保养手册要求每六年或六万英里更换火花塞，我的E350（M276）已经六年了，换吧。注意，奔驰的维修手册要求拆掉进气总管，以方便拆掉点火模块，但那必须更换进气总管与进气歧管间的密封圈，费钱、费事又费力。按照我的方法可以省掉那些步骤和钱。
This video can easily be used to train the mechanics for Mercedes-Benz. From the clarity of the steps to the quality of the light in the picture. This is truly old school. Reminds me of my Grandpa and my father working on car. We need to bring back this multi skill talented people.
Without saying a word, this made more sense to me than any other video.
Thank you so much
Thanks and welcome to visit www.leighsr.com/spark-plugs-replace-m276 and discuss on leighsr.com/forum
Sir, this is the best video out there for W212 with M276 engines. The video is well edited and shows every detail of the removal.
Sir, Thank you.
Everything about this video from the content, the video production and actual craftsmanship was exceptional. Well done Senior Leigh!
Thank you. Good to see you don’t need to remove intake.
You made this look easy. Just changed mine today and for those of you who have large hands like mine, the support for the wires comes off via removal of a torx screw and the other portion comes off the carriage just low of the coils. Makes life a little bit easier.
Good video.
Is it easier to go under the car?
Wow! Compare to other videos out there, you make this process look easy! 👏🏾 nicely done, sir!
I'm very happy you like my video❤️, I try to make detail clear by the video language, but still something roughly. So I'm building a website for clear most detail of my video. Coming soon.
@@LeighSr... Japan
The other world.... Big like for u man
That's because other videos show removing the manifold as a requirement, which is wrong!
Thank you for this great video. This was my very first project on any MB (we have same year and model). This information gave me the confidence to take on the task and helped ensure my success in changing the coils and plugs.
Hi Senior Leigh and to all your subscribers . So i remember a while back I was suppose to let you and the group know if I was successful in installing new timing chain rattle kit for my 2012 Mercedes E300 M276 engine. Thanks to all the pdf you have on your website I got the job done. I know how to set the engine timing completely . I installed updated tensioners , check valves and new camshaft solenoids on my engine. I did also check all my cam shaft actuators and they are good none was slipping and spewing oil from the front so that was great. My car sounds beautiful now all the rattling i heard is gone. If later on one my cam shaft actuator goes i will attempt that job myself and let you know. I am even more in love with my car now . I really want to thank you for the information you sent me your an angel sent from the skies I just want to thank you.
That’s sooooo great job! I am very happy I can provide what you needed! Could you please upload a short video to share with your pleasant engine sound on the Leighsr.com/forum, I can’t wait to hear it ❤️
Thank you for your video. Changing the left spark plugs are more easier than the right one. I wonder how MB couldn’t find easier way than this.
Well, thank you so much, it would take me forever to figure how to best remove cylinder 6 spark plug. I already tried twice to get 6th spark plug out with no success, after watching this video, I did it like a charm
Hello, you have some of the most valuable videos on how to in the w212 MB platform. Thank you for your time.
Senior, this was a wonderful video! Beautiful editing and filming!
Senior Leigh, great detailed video, it's the best I've seen. Please consider posting a how-to radiator flush video for Mercedes W212.
Thank you so much.. I just did mine today and your video helped me a lot. I did at 76000 and spark plugs still looks good. When I connected the F cable to ECU, I believe my fan ran for couple seconds as I could see some dust flying, first I thought something burnt but no burning smell and car works without any issues/code. So I realized it could be the fan.
Very helpful. One note for followers. Note the technique he uses to remove the coil connector. It's SUBTLE! Once you pull out the grey lock... you need to push DOWN on the end of it (quite a bit) to actually release the mechanism and allow the connector to just slip off by pushing with another screw driver. I unfortunately didn't notice this until I had broken a connector. Not bad enough to be unusable but still broken. If you do it right the connector just slips right off.
Is this the part between the 2:18 and 2:25 of the video?
Great video. I used it for a 2015 GLK 350 (X204) - saved me removing the manifold. The center coil connector (ECU side) wouldn't come off, but I can confirm you can leave it connected and still remove the coil.
Mr. Leigh, your videos are superb. Thank you very much.
Glad I found this video! I guess I don't need to take off intake Thanks for sharing. you got awesome tools
Just finished changing out my plugs thanks to you it too me 2hrs
Hey Pat did the coils come off easily and what challenges do i face doing this job?
I can feel more powerful with new spark plugs, even the replaced spark plugs still in good condition, as you can see that in the video......after a few days watching, the fuel consumption has approx 2 mpg lower than before replacing the spark plugs.
Wow! That's significant. What was the mileage on the old spark plugs?
@@Jil1A From 19 mpg to 21 mpg on a typical road.
@@LeighSr Thanks but I meant how many miles were driven using the old spark plugs before you replaced them?
@@Jil1A Sorry for the misunderstanding, that's approx. 50k for 6 yrs.
@@LeighSr Alright. Thanks for the info. The reason I'm asking is because my 2012 C300 only has 31k miles. I'm wondering when I should chnage the spark plugs because MB calls for 100k miles but it'll take me more than 3-4 years to get to 100k. So do I wait till then or change them sooner and when? Thanks.
Great video, so professional! You make it look so easy but I know it is not as easy as it looks. Thanks again.
Actually that’s not difficult 😅
Hi Senior the serpentine belt,tensioners and idley pulleys went well bearings were bad on all of them you can here the difference now on start up so quiet. Thank you again Sir execllent pdf information on your website.
OUTSTANDING VIDEO !!!!
Your the best I just knew it had to be a way without removing the intake
Excellent video. I feel more confident doing it myself after watching it.
Great video, great detail! Just subscribed with both my youtube accounts 👍
Thanks for the video. One thing I can add, is the coil boot/plastic protector for the boot breaks quite easily even when using the boot puller tool, at least for me. Doing the job in 2024 on a 2014 with 90k means 1000's of heat cycles and those boots were so stuck it wasn't even funny. Broke 4 of the 6 removing them and needed to replace, just FYI for those getting ready to do this project. You can get replacement boots on rockauto for $5 per.
Very useful video! Thanks man and respect for this job!
lost art lets keep this trade alive thank you for posting
Very nice video and really happy to see how to replace plug & coils at driver seat side without taking off intake manifold that most of video do it. However, it looks very tough for beginner to follow. I am afraid of falling down coil bolt..^^ Anyway, thank you and it helps a lot for me to challenge it.
Very nicely laid out
Genius method to avoid removing the intake plenum which makes the job much longer and expensive. Do you have to remove the battery connector before removing the ECU? Did it cause any errors once the car was started due to the missing ECU? Thanks for sharing the video.
Thank you, and no necessary to disconnect the battery. Once you disconnect the battery, many errors codes will be stored in the OBD, you have to erase it by MB Star. Switch off the ignition and remove the key away, disconnect the ECU, when you finished the work connect it again, the ECU won't know what happened, so no error code. BTW, disconnect the ECU is a way to prevent steal when you parking in the street for a long time.

The best video ever ever
great video and thank you for the links to the tools. I don't see any info on the star drive bit that you use at the beginning when removing the ecu or for the socket used to remove the bolts holding the coil packs on. Can you give us that info when you get a chance? Thanks in advance!
Nevermind, I found them on your website. For anyone who reads this and wonders the answer to my question is: T27 socket bit, and e-torx star socket (see here here en.leighsr.com/spark-plugs-replace-m276)
You have got to be kidding me....you didn't take off the intake manifold?I've watched videos before and they took off a bunch of crap....including me and here comes this guy and he makes it look like a piece of 🎂....wish I had seen this video before
You are best and very clearly video wow. Thanks :)
Big fan of copper anti-seize on the spark plug threads. After all, they are a chassis-ground component. Speaking of: Watched you clean the throttle body for this engine. You can realize a similar level of performance improvement if you clean all chassis ground connections, esp. the alternator ground strap.
So many people break locking clips/latches on the ignition coil connectors while trying to disconnect them. I broke 3 out of 6. I was careful but they were so baked to the coil with heat. It is not as easy as you see in the video demo by Senior Leigh
Best I have ever seen
Thanks. I subscribe to your channel. Very good video edit. I have the same car and motor and i love this being my first Mercedes. I thought that you have to remove the intake plenum as ive seen on some video's. But this save me time and money. Thanks. Cant wait for your next video sir!
MR2DSP You’re welcome. The repairing booklet of Mercedes only a reference. I have broken twice of the repairing guide, last time was “replacing ball joint boot of control arm instead replacing whole control arm”. See my earlier video.
@@LeighSr I have 52 k miles on my 2013 e350 sport should I replace the plugs at this Miles ?
MR2DSP Almost same mileage with my 2013 E350. The spark plug replacing requirement for 6 years or 60,000 miles of all modern Mercedes on the maintenance booklet what is working with iridium spark plugs. So I think that’s time to replace them.
This is outstanding! Thank you!!!
What torque bit did you use when you used it to take of the engine computer
ECU does not have any torque bit, it held by 4 rubber grommet. You can just pull the ECU from bottom and it will lift up. Torque bits you need E10 - Engine Air Filter. E8 - Spark plugs ignition coil. T25 - Remove the Bracket on the driver side to give you some room. Hope this help. Warning, don't try this job without the spark plug removal tool shown here. You will regret if you do. Happy wrenching...
Very enjoyable video.
Did you blow out spark plug holes with compressed air before removing the spark plugs?
Why didn't you replace the spark plug boots at this service as recommended?
The detailed way you perform Mercedes service makes me think you are a mechanical engineer?
This dude was about to commit suicide in his garage 😂. Just kidding. Great Video!
My respects! Nothing more to say.
Very very HELPFUL thanks
Just did this it took me about 12 hours bc I had to stop and go buy tools I didn’t have make sure u do intake gaskets while ur at it and check for oil in engine harness
abs 老法师👍👍👍
Thanks for this very informative video. I will try to do it on my 2014 E350 base model 4 door. I wonder where did you get the pdf documents displayed in your laptop? Also the spark plug socket you specified on ebay does not meet the compatibility test for my model car. Thanks for a prompt reply.
I'm happy u like my video. The documents were pulled from the WIS of the Mercedes diagnosis system (I purchased on ebay.to/2NlYWWO). For the spark plug socket, don't worry, that is 14mm 12 points socket is fit Bosch spark plugs of Mercedes, due to almost all of the vehicles were made in Germany using bosch speak plugs.
Very nice! There are very few good videos on YT for the M276 engine. Please consider doing one on replacing the water pump of this engine. I cannot find any video on that, yet it is a procedure that sooner or later will be necessary (I need to do it on mine). I hear that it is necessary to remove the intake manifold. Thank you for your many great videos.
I'm happy you like my video. And I scheduled to replace the ATF of the 7G transmission next week. For water pump replacing, if you have to replace it I can send you the replacing guide what I pull out from Mercedes repairing booklet.
Senior Leigh, thank you very much for your offer to send me the guide for replacing the water pump! I will take you up on it. How can we go about doing that? Thanks again.
@@maxagent86 Let me know the model year, chassis and engine. And once I get the replacing guide, I'll paste a link here.
Senior Leigh, it is a 2012 R350 long wheel base, model W251.157 with the M276 engine. Thank you again,
@@maxagent86 Replacing coolant pump, right? And Is that a natural aspirated engine?
Excellent video, thank you
I had a W210 E320 V6, my mechanic bought it off me and he still has it (23 years old!). It had twin sparks so come changing time had to buy 12 plugs.
Yeah, that’s true.
A very well produced video, thanks!
I ran into a problem that maybe someone can help me with. On cylinder #6, the coil boot separated from the ignition coil when I tried to remove it using the Lisle tool. Now the boot is stuck to the spark plug and when I tried to pull it out, the hard tab broke off.
How do I get the boot off? Can I spray Kroil or WD-40 directly into the top of the boot where I can see the metal contact and hope the oil gets to the plug?
The 6th spark plug is the most difficult to remove. That must be sucked too tight with spark plug and the boot. I think you can fill the WD40 into the hole of spark plug, and wait a couple of hours. Let the WD-40 sock into the gap. That would be easy pull the boot out.
@@LeighSr Thank you for the reply.
Great Video SL. I was thinking about replacing spark plugs and intake plenum gasket at the same time, but after watching your video and others youtubers trying to take intake manifold out I prefer your method better if intake plenum gasket does not need to be replaced. At what mileage do we need to replace the gasket? 2014 W212 65,000mls
Thanks for your praise! In my opinion, the gasket no necessary to replace unless you take out the intake plenum.
It's very helpful video for DIY, should I replace the Spark plugs and the Ignition coil ? my 2014 E350 has 62,524 miles, rough Idle. Please advice, thanks
The spark plugs should be replaced every 60k miles or 6 years; the ignition coil can last lifetime until it’s damaged.
Thank you for the awesome video. I am debating between letting a european shop do this job for me at a cost of $768 or tackling it myself. I have done other maintenance to my cars before but I just bought this W212 and I don't want to mess it up. Nevertheless you do make it look pretty straight forward and I thank you for it. Can you answer a couple of questions for me to help me on the decision: how hard do you have to pull on the spark plug boots? When you're putting them back, how much force do you need to push the same boots back on?
Perfect
Do u know why 2016 Mercedes Ben m276 oil leak out from oil filler cap I went n buy New cap from the dealer still leaking out please help if u can thanks you.😊
Thanks!❤
Well done. Thumbs up. 👍🔧
Thanks for the video do u have to disconnect the battery before unplugging the big connectors on the computer
Milad Baaklini No, no necessary to disconnect the battery, switched off the ignition and pull off the key is ok. Just bear in mind, every disconnecting and reconnecting the battery will generate many error codes stored in the OBD, you have to delete them by MB star SD.
Thanks for the info makes sense
i dont have the spark plug boot removal pliers, you think it would be okay to perform the job?
outstanding video btw. i love watching ur vids after my daughter goes to sleep
I'm happy you like my video. And say hello to your daughter for me. For Spark Plug boot Removal Plier, I strongly recommend purchasing one. Considering the ignition coils have sat the position 6 years, the boot holds the spark plug tail pretty tight, they never separated since 6 years ago, LOL. Also, the ignition coil is more expensive than the plier. When you pull them off with strength continuously instead of suddenly to avoid breaking the ignition. At the last make sure the ignition coil seat correct position to firmly connect to the connector of the spark plug. If there has abnormal vibration with the engine while you start the engine, there must be an ignition coil connected incorrectly. Don't worry, connect it again. Replacing the spark plug is not a difficult job, just patient, Good luck!
Did you have to unplug the battery at all before you started? I don't want any codes showing up after I change the plugs.
No necessary to disconnect the cable of battery. Let's imagine that the ECU do not know anything what we did after switching off the ignition. Any error code is stored by our mistake of the operating after engine running, even we disconnect the cable of battery before we replacing the spark plugs.
As always very nice and clean job! You're not using spark plug anti seize on threads?
Thanks for your praise❤️😄，And yes, in Bosch brochure, there is a word: "the Bosch Nickel-plated shell with rolled threads requires no anti-seize". The brochure link: www.boschautoparts.com/documents/101512/0/0/7cacfcc7-745a-4249-9916-bf8079c7a542
Not to mention anti seize is a lubricant and torque specs are not the same with lubricant.
That's why you own MB, DIY save a lot $$$ labour.
In my opinion, the DIY is a attitude of the life, a feeling of happiness... In some cases, DIY may be waste time, waste money, but that cannot stop me gaining the happiness. No regarding brand, Metcedes, Toyota or Citroen, etc.
Wonderful video thank you
Thank you so much for this video! Completed this job today, unfortunately one of the ignition coil bolts slipped out of my hands and is somewhere in the engine. Do you happen to have a part number?
2761590042 is the part number.
@@LeighSr Thank you!
Thank you for posting this video. Will attempt the spark plug swap this week. Have read conflicting information regarding if I need to index or not index spark plugs. What is your opinion on this?
Thanks, and in my opinion, the index spark plugs are the old school. And now the ignite spark energy is much more stronger than before, the indexing is not necessary for the modern engine. Also the Mercedes must be considered the best way to optimize the engine. The index is always the right things to do, but I think the benefit is too small to be ignored. So we just follow the WIS to maintenance our Mercedes and peace of mind. 🤝
@@LeighSr thank you sir
I own a 1999 C280 with 97,000 molies still has the original spark plugs, I bought the car new. It is a V6 engine looks like a hard job to change the plugs
Nice car, and yes she has 12 spark plugs for the M112 engine. For a 97,000 miles engine, you have to replace the spark plugs.
A very good quality of the video. It takes some skill to make a video like this. What camera was used to make this video?
Thank you, and my camera including DSLR, GoPro, and camcorder.

Thank you! Very helpful information.
Hi Senior so I got my Coils and spark plugs changed. I followed the procedure you have on pdf and all went great car feels more quicker and smoother thanks for the great help. I may undertake a next late summer or Fall project and thats to install rattle kit that mercedes recommended . I am looking for info on how to have engine set at right timing positon. Can you post something on websit so i can read up a bit about the procedure?
Not a problem. And we might discuss the details on the forum of leighsr.come
@@LeighSr yes sounds good am doing the tensioner ,idle pulleys and serpentine belt this weekend i will let you know how its all work out.
Hi Senior Leigh so i did the intake Plenium manifold change and it went excellent. You are correct i did not have to disconnect battery i just kept the key atleast 200m away from the car. The procedure you posted is excellent thank. I will attempt the timing chain tensioners and check valve . I hope i set the timing right before i remove tensioner. I may have a hard time getting the tool to press check valve in its pretty hard to get i heard.
Are you indexing the plugs?
Hello,
Great video, best I have seen. What is the torque specs for the plugs and coil packs. I didn't see it in the information that was listed.
Thanks in advance
Chris Juhl thank you and the torque specs were showed at 48” and 1’06”. That’s 23Nm and 9Nm. More details I will upload to Leigh’s.com
Senior Leigh. I have a question. When you remove the battery. Do you have to program the radio and other stuff. Thanks so much
I used to replace the battery twice for the W221, no any issue occurs with the radio (COMAND) and other equipment. Everything will recovery after disconnect/connect battery. So don't worry about it.
@@LeighSr Thank you!
MR2DSP You’re welcome .
very good video
Warning using those 3/8 to 1/2 socket adapters with a torque wrench will result in a incorrect torque reading
Hi Senior Leigh. Quick question if you dont mind. Did you have to reflash the computer when you removed. I would like to replace my plugs this weekend however nervous as I have been told I may need to have it reflashed due to removal.... thanks for your help and the very helpful videos for us.
Cory Machell as my understanding, you mean the ECU removing, depends on MB WIS, there is no re-flashing needed after disconnecting and connecting the ECU. If that’s necessary, that would increase workload for workshop, no, MB won’t do that. Thanks your compliment as well❤️
@@LeighSr you are right. Forget being nervous and just do it. Thanks again. You are a great help.
How would I be able to get my service manual?
Great job great video
what size spark plug socket is used?
Wat about indexing spark plugs on this engine m276 ? Thanku senior leigh
Senior Leigh I need your help, I bought a used a w212 m276 and kind of regret it I always buy lexus or toyota and this is my first mercedes, the check engine light comes on and goes away for last few days I first changed the oil, air filter, cleaned throttle body, last time the check engine light came on and car was misfiring while i was driving so I pulled over and with obd scanner cleared the code for misfire cynlder 6 and it went away and its ok for a few days but im nervous to drive it do you think its the plugs or coil or something else? I am waiting for it to come back before i start repairs
Easiest way to find if it’s ignition coil to interchange ignition coil from 5-6 cylinder and see if you can replicate the issue on cylinder 5. As you can see cylinder 5 & 6 is the most toughest, I would suggest to buy 1 ignition coil for cylinder 6. I saw the same issue you are having with same engine for other people and it’s most likely spark plug not the ignition coil. Hope this helps
Great video which gives me confidence to do it my self..thanks.
I have E300 2014 that use the same engine M276 and I got a DTC P0304 misfire on cylinder 4 and engine starts shaking, this happens only at first start in the morning! Not sure what is problem but I never changed the spark plugs before, current mileage is 75K.
Can you help me to locate cylinder 4? Thanks in advance
Abo Abdullah thanks for your compliment! And the 4th cylinder just behind the ECU, if you face the vehicle, that’s located at right and nearest of you. More details at www.leighsr.com/spark-plugs-replace-m276

一如既往的好。不明白benz 为什么把ECU和线束布置在温度这么高的地方。
谢谢兄弟的夸奖！我想这也是奔驰对自己产品的用料有足够的信心吧（耐高温，抗老化）。奔驰的发动机可靠性排名世界第三，仅次于本田和丰田，但安全性和舒适性就远超那两位了。
Can you please do a video plenum removal thank you so much. Hopefully on a W212.
Do you mean resonance intake manifold? You www.leighsr.com/spark-plugs-replace-m276, at the end of the page, there is a guide to remove it (PDF).
When I tried on the passenger side while changed the air filter I couldn’t get the clip off the coil pack so I just pulled it out while it was still connected, is that bad? Couldn’t change the plugs anyways because you need a special skinny deep socket, go figure
If you can pull out the coil without damage the wire, that's ok to with the wire connected. For the tools, I always use the handy tools on my work.
May I have my C240 back? This looks nightmarish.
Hi thank you for the video, what is the torque value for the spark plug?
23Nm that’s required by Bosch and Mercedes.
The clip for the wire attached to the ecu fell into the engine bay and I could not see it. Do you know how to get replacement or part number?
I think that's hard to find a replacement. If I were you I might raise the front of the car and remove the bottom panel, the clip must on the panel. 😄 😂
@senior Leigh what’s the torque specs for the spark plugs?
23Nm
Hi Senior Leigh does the Pdf documents you purchase from ebay give you details of doing the job your performing and can i purchase software separate without scanner?
The pdf is experts from the WIS of MB. That’s the workshop information system which comes with the MB Star. Can not get it separately.
how do you remove those ECU wires from the tie down clip (zip tie) from the bracket? it seems to be screwed on?
There has no zip tie tied the ECU wire and the bracket. More detail on www.leighsr.com/spark-plugs-replace-m276, we may discuss on there.
Mr. Leigh, you removed a small bracket right after you removed the module, correct? This is attached to the large bracket, right? I did this job and couldn't figure out how it detached, and had to unbolt the large bracket near the front.
Paul Santos I’m not sure which bolt you can not remove, could you post a thread with picture on leighsr.com/forum so we can discuss it?

Song Hei Pou 我知道奔驰有“方便进出”的功能，熄火后，S-class的方向盘会上升，座椅会后退；E和C-class只是方向盘抬升。启动后再还原到之前设定的位置。如果您指的是这个功能不灵了，那就是方向盘处于最高点下不来了，用手动调节也下不来。很可能是齿轮卡住了，简单的临时解决办法，就是：左手向下搬调节按钮的同时，右手从上向下猛击方向盘上沿……基本会解决；过一段时间又会卡住，永久解决办法是升级程序，把上止点的位置下移一点，就不会再卡住了。

And I also found there was filled full of dielectric grease in the connector of the ECU. So I think those worries are unnecessary, just use it and rigid free.
