Welcome to leighsr.com to discuss.
The Vibration is the most annoying at idle, especially in a luxury car. And the most reason is dirty of the throttle body, let's tear it down to clean it deeply.
怠速抖动是一件比较烦人的事，尤其还是一辆豪华车。大多数原因是因为节气门体脏了。拆下来彻底清洗是最好的解决办法。

I have a 2013 C300 with the m276 engine and your videos as well as the website tutorial on changing the spark plugs help so much. I’m a mechanical engineering student so it’s really expensive for me to get a dealer or shop to do everything that I would rather do myself with the knowledge. Thanks for everything you do. I really appreciate it. Liked and subscribed!
Jaylon Hanible thanks for your compliment, and yes DIY let me save tons of money from the dealer. As a Mercedes owner, keep a Mercedes is away lower cost than a Toyota’s owner who only work with a dealer.
Also, I’m building a website to detail every video. leighsr.com
The editing in general, especially the part showing the interior and materials used was very nice.
Thoroughly enjoyed your work, you have a great style of working like an artist. Keep the Mercedes maintenance videos coming Senior Leigh!
Very good sir. This is the first video of yours that I have seen. It is very nice to watch a gentleman work. I admire your precise work and perfect care of tools and organization. Thank you. I subscribed.
Nicely done maintenance!
While you were in there.... you missed a chance to lube the intermediate gear shaft inside the throttle body.
Between the 12V throttle motor and throttle plate gearing there is a (plastic) gear shaft that wears out when kept puposely dry...
I used high-temp silicon brake grease on mine to give my unit a long service life like new without any loose free-play.
Dankeschön für das tolle Video, Senior Leigh.
看到您影片開頭車輛轉速錶的穩定情況還真沒想到您要整理那個節氣門，這也才明白您這節目叫「玩」修車的原因。我在台灣是個修理印刷機的技工，由於工具齊全，又基於對機械的愛好，所以我上輛Lexus除了引擎本體都讓我拆了個大概，目的也不是修理他的故障，就是想讓車子呈現我要她的理想表現。而今呢，退休了，沒了場地，沒了工具，徒然對車子有些了解，但面對新的梅賽德斯無可奈何，所以看到您的環境、工具與「玩修車」精神實在令人羨慕。
非常感謝您的關注與交流🙏，沒有自己親自操作條件的話，建議您找一家可靠的小型修理廠作為依託，同時您也可以更多地參與、指導，也不失為玩車樂趣的延伸🤝。
Fantastic video and great results. Thank you very much.
Very nicely done!
The reason you have oil build up in the intake is your PCV and breather valve are worn and require replacement. That will cut down on oil in the intake.
Awesome video and info. Thank u Sir.
Thanks for such a detailed and clean dedicated work. I have always wondered on the canister side of the throttle body and how to empty any oil in it. While we think about the throttle body, it is also wise to empty and clean any oil in the area and the canister. It can be a source of dirt for the throttle body.
Thank you and yes, you are right. The crankcase oil steam was burn get through the throttle valve. That's for environmental protection，but will dirty the throttle valve. If the oil steam too much, it will be collected to the container under the suction hose.
@@LeighSr Do you clean air phlem for burn oil at the valves? If yes, with what?
SUPER VIDEO! Th.Henry
Thank you so much!
you are real man
I have to say,you r pro
Senior Leigh, as always, great video. I noticed that you reset actuator values using Xentry. If one does not have the software does the actuator reset or relearn automatically after driving?
Thank you.
And yes, that will do. Every time you turn on the ignition switch (no ignition), you will hear the throttle valve moving (loudly), that is resetting automatically. In addition, the opening degree of the throttle valve is mainly determined by various signals such as intake sensor, speed, crankshaft position sensor and knock sensor. I use a computer to reset, just to confirm.
Thanks! Great, useful, video. It looks like you already changed the MAF sensor previously (doesn't look like the original Bosch part for this engine) and I imagine that didn't solve the rough idle problem. Just cleaned my MAF and still have rough idling (after the Mercedes mechanics left the intake clip loose), so I'll do the throttle body next and see if that helps.
Thank you and actually the M276 don’t has the MAF sensor, Instead with a temperature sensor in front of the throttle body.
Great video. Wonder why oil in the throttle body? Is this by design? Looks like oil might make it to air filter box.
😻😻 so relaxing
老師 謝謝
不敢稱老師，大家互相探討。
Another great job, could be done when changing spark plugs. I had thought those metal clamps were one-time-use Oetiker clamps that Audi also uses. Thanks
Thank you. and yes, the clamps are one-time-use as required as MB WIS. But after checking carefully, I think those may reuseable. And no issue tile now for one year.
@@LeighSr I will try your technique when I need to remove these type of clamps.
@@A4nKar There is a specific removal/replacement tool for those which you can probably find on Amazon.
Another great video and thanks. I've noticed in your video's that the front timing cover bolt heads are painted blue. Does the engine come from the factory with them like that or have they been renewed after work being done in that area. The reason I ask is that I would like to fit oil check valves and up graded tensioners but I'm not sure if they haven't been done already.
Thanks and if you wanna ensure there are check valves in your engine, just check the engine number. For M2769, if the engine number is less than 2769xx 30 406603, that does not have the check valves. Input your VIN on www.vindecoderz.com to check the engine number.
what is that black piece on the side of the throttle body? can it be removed/replaced or cleaned? I saw some oil on the side of mines all the way down to the oil catch can. No codes. im wondering if i should do anything more than what you did in this video?
It would be an excellent video to show how to replace the crankcase ventilation valve or PCV, I know it requires a lot of work to replace it. I just don't have the courage to do it myself, I tried but never got it done. I got so much oil in my intake, I have to wipe out oils every weekend or whenever I have time. That's not good at all, I got frustrated with MB as to why they designing such weak parts.
DIY也能做到如此專業👍
想請問電子節氣門清潔後是否需要電腦復位
沒診斷電腦的也能自行清潔嗎？
可以的，没问题。每次打开点火开关时（没有点火），你都会听到节气门在动作（声音很大的），那就是在自动复位。另外，节气门的开度主要根据进气传感器、转速、曲轴位置传感器以及爆震传感器等等多种信号来确定开度的。我用电脑复位，是确认一下而已。
Great video Senior Leigh, thank you very much for making such high quality productions. I was wondering if you could tell me how to get new clic type clamps for the air intake boot. You seem to be using new ones from a plastic bag, is there any chance you could give me a part number? I can't seem to find them anywhere. Thank you!!
Thank you and the hose clamp part no: 0019950135
@@LeighSr Wow, you replied in 10 minutes. You are indeed great, good sir! Thank you!
Never realized the M276 had a catch can
Where can I get that diagnostic device?🐼
Hi, do you have a video on how to clean the MAF sensor for Mercedes 2013 C300 W204 with M276 Engine?
addynayar13 not yet, maybe later I would try it.
Hello Senior Leigh! I have a quick question. I noticed you used the SDconnect to reset the adaptation values, is this necessary? Because in the WIS/ASRA manual they do not state this step for the throttle valve. Thanks!
Actually that is not necessary to reset by SDconnect, the car will automatically correct the position of the throttle valve. Btw, I have not found a document of cleaning the throttle body on WIS. If you have that, could you please post them on the forum of leighsr.com? Thanks!
@@LeighSr Thanks for the help!!
I like your vids and u got a real class but i would avoid spraying anything around TB flap spindle, those dissolving fluids can damage grease inside those spindle bearings and TB can stuck or stop woking at all. I use toothbrush with some solvent on it or just a piece of cloth soaked with any solvent to clean \ remove all that dirt buld up.
Thanks for your advise.
@@LeighSr No problem, thank you for your content. Really great channel, one of the best maintenance vids i ever seen, quality, editing, attention to details, style, u got it all. And since its a merc then maybe add some light classic music for background to add even more class )
and about the fuel filter change,for the E350 Mercedes Benz diesel bluetec, do you have it video??
What’s your Diesel engine model?
Any video on how to change chain tensioner
Not yet, maybe later I could establish a guide on leighsr.com
What is the part number for the clamps that you replaced?

What is the part number for the two clamps and where did you buy them?

My 2016 E400 4matic Coupe just threw the P2101 code Throttle Actuator. Is that the assembly attached to the Throttle body?
Yes, the step motor of the throttle body.
非常喜欢您注重细节的态度。看您的工具收纳就很舒服。节气门那段橡胶管子上的灰再一起清干净就更完美了，看着白撩撩的灰我强迫症犯了😄。想请问您检测电脑在哪里购买的？我刚入手一辆16款E350四驱，跑了不到三万迈，发动机有呱呱的异响。还想请问您认为是什么原因造成的呢？是不是M276发动机的通病呢？谢谢李大哥🙏
Michael LIU 谢谢您的点评🙏……检测电脑是在eBay上买的，链接在视频下面有。……呱呱声是在什么状态下出现的？
Senior Leigh 前几日预约了今天去奔驰Dealer做检测。一大早赶过去了，人家什么设备都没用，看看听听就说这是正常的声音。车子有问题的话车载电脑会有提示。完了，这就给打发走了😂。可能是奔驰发动机特有的声音吧。我还是先学您好好保养它。期待您各种M276发动机维护的视频👍
@@michaelliu1162 我是经历了dealer的各种糊弄与不专业以后才奋起DIY的😄。如果您认为有不正常的声音从发动机传出来，建议您买的一个车用的听诊器（amzn.to/2Mw8I7O），定位出异响的位置，然后到网上查一查相关的资料，看是否正常。正时链条的上部，也就是气门可变正时机构，可以重点检查。
Senior Leigh 李大哥我们微信联系可以吗？
Michael LIU 实在抱歉！我不用微信。
Do you have to disconnect your battery terminal during this service?
No, no necessary.
Looked quite clean to me to begin with. Not sure if this little accumulation has any negative impact on performance. Juice doesn’t seem worth the squeeze. Right?
You might don’t clean it at this condition, but as the little cup of water test in the video, that is working for cleaning the throttle body.
Thank You ! Can you just clean the throttle body ? Do you have to reset with computer ? I don't have any of that stuff.
Sure, you can just clean it without reset by a computer, and the ECU will learn the position of the throttle body after you clean it. There are many sensors to help the ECU to determine the right things. I use the Diagnosis to reset is just for double-check. In a quiet place like a garage, when you turn the key to the ON, not ignition, you might hear the sound of throttle turning. That's the ECU makes the throttle learning.
Your awesome.
@@LeighSr ho-see-foo-ah 🤗
@@LeighSr many thanks, Senior Leigh. I was thinking it is a must to rest by a computer but your confirmation is a relief 😌
I cleaned the throttle body and everything was perfect 👌. Also no need to relearn the ecu..
2014 E350 4 Matic Just cleaned mines also changed my air filter and let me tell you it was completely full of bugs. Idle is smoother now I also had a little oil in the intake is that bad?
Oil in the intake is normal for this motor
@@NateEll wow really that’s interesting have another issue my dipstick keeps popping up not a lot just a little bit maybe need a new o ring ?
Senior Leigh, I’m not sure what to do… I cleaned the Air Intake Manifold exactly as you detailed on the same model W212 MB and I immediately was put into “Pre-Safe” mode. I spent a couple hours troubleshooting the issue with no luck, and eventually decided to unplug the front and external batteries.
This worked, and my E350 was running great! Yesterday I drove for about 80 miles but on the way home the same thing happened abruptly. I was stuck in “Pre-Safe” mode about 2 miles from my house. So I had to “drive” a few miles back home like that and decided to deal with it in the morning.
Now the morning has come, I reset my battery, and to no avail… the engine shuts off after starting! This feels like a massive bill, and I’m quite worried there’s been some greater damage done to the engine. Please help!
Note: 79k miles this is the first time Intake had been cleaned.
I consider there would be two potential problems, a sensor connector do not seating properly, or a sensor was covered by some debris. So follow this thread to checking. If you have a diagnosis system can read the error code, that would be easy to find the problem.
@@LeighSr Okay I'll order sensor cleaner and reseat all of the components. I'll also order a diagnosis system from eBay, unless only the MB-Xentry setup works? Thank you for the advice, you truly are the best Mr. Leigh.
@@Deadshadows If you only do regular work on your MB, no necessary to buy a Xentry, a third party diagnosis system is good enough. Like iCarsoft MBII for Mercedes Benz amzn.to/2SbcYMR
@@LeighSr I just placed the order, was down a rabbit hole of options. You are a godsend! I'll have an update on Sunday when it arrives. Again, thank you Mr. Leigh
@@LeighSr Good news, it’s fixed! I first tried resetting the Throttle System via iCarsoft but it would not complete…Like you presumed, the ATC 6-pin plug was not seated entirely.
The MB II diagnostic system is very useful. Thank you for your help Mr. Leigh, you are the true hero in this situation.
Take care,
DS
hi. should I disconnect the battery before cleaning or it's not necessary?
No necessary to disconnect the battery, also, every reconnect the battery, there will generate many error codes were stored in the OBD. You have to erase them by Star SD.
Senior Leigh thank you so much
Why to clean?? Was clean.
Where can I buy the Xentry or that pc to diagnose the merc
I bought the MB star SD connect C4 on ebay.to/2NlYWWO
great!
Is this a Diesel engine? Because gas engine has the throttle body way in the back in a hard to reach spot
It’s gasoline engine M276. More details on www.leighsr.com/m276
On my 2014 Nissan Maxima VQ35DE, manually moving the throttle body butterfly will damage the sensor, and possibly ruin the throttle body. Apparently this is not the case with the M276?
No, as my experience the Mercedes is sturdy and tough with fault tolerance mechanism.
@@LeighSr Thanks for the reply! Also, would you happen to know where the MAF is located? I cannot find one for the M276. Does this car even have one? Sorry for all the questions, I just bought my first Mercedes on Valentines day, a 2013 E350 Sport P1.
@@CORZER0 congratulate you have a Mercedes and I promise you will love her with the driving feeling.
And yes, m276 has MAF. That’s located at the intake pipe between the air filter housing and the throttle body. I’m going to clean it later and recording a video.
@@LeighSr Cool! Thanks! I subscribed so I'll get the notification. Much appreciated! Learning a lot from you.
@@CORZER0 thanks for subscribing and also welcome to Leighsr.com I’m keep to update the content.
the purpose of the throttle cleaning was to take car of the rough idle . How about misfiring issue will cleaning the throttle will fix that .
The misfire is mostly by a fault spark plug.
不好意思， 我想借这个机会请教各位，不知道这颗M276的引擎怎么样呢？ 可不可靠？维修成本方面又是怎么样？ 先谢谢大家了。目前正在考虑宝马的N55和奔驰的M276。
How often do I need to clean it
That depends on your driving environment. I live in southern California, the milage approx 50k when I first clean it. So on my condition, I'll clean it every 50k miles.
What model year is that?
2013
需要用电脑重新学习节气门吗
不需要。
这么干净还洗哈哈。mercedes老车不太敢动，管路都太脆了。
下雨天打孩子……😂
节气门这么干净还洗啥
為了拍視頻😂😂
牙刷牙刷
哈哈，下回洗S的时候用牙刷。
