I've seen an other video in which the guy disconnects everything to get the manifold lift up a little in the front and changing the broken lever and middle vacuum-pot. I didn't figure out how that guy made sure not to damage the gaskets/sealing- but anyway to me it seems a lot of work to do and replacing the whole makes sense in a way then, even more once it is removed and you still want to drive the car for couple of years. Found the pierburg manifold for my M272 for about 600-700€ and think is worth it because it's all clean, new connectors, vacuum-pots etc . Thanks for the really great video and explanations !
Nice. Only thing is the new manifold appears to have the same doomed to fail plastic flap lever that the original had. Oil and sludge build up on the inside flaps can be avoided by changing out the oil separator diaphragm thing behind the passenger side valve cover on a regular basis
Amazing video, thanks! It enabled me to replace the intake manifold of my car within a short time and without faults. Great!
Excellent helpful and clear video instructions, thanks
Thanks for going into such detail. I am going to do this on my 2007 E550 and I am much more confident having your video on-hand to reference. I have 142k miles and will replace the fuel injectors as well.
David,
I would not change the injectors unless you know for sure that they are not good. Just Use a can of liqui Moly injector cleaner or BG44K.
For any reason You have to change the injectors I suggest it to be done in two separate operations, so in case You have a problem such as the engine running rough afterward, you won't be confused whether it's related to the injectors or the intake manifold.
I have pretty much explained everything in that video and I left nothing to be guessed or questioned.
Good luck.
This video was excellent! I have a 2011 R350 with this issue, and after watching this video I'm sure I can tackle this with ease! Thank you for your detailed information!
Keep us informed.
I have 09 E350 with 55K miles and it drives like brand new. I've been checking this flaps on my car every 1st day of the months for a last 2 years (Never missed). But it broke on 1st of May when i was checjing the flaps.. The damage was at the same spot in this video. The broken piece still attached with the middle rod. The car felt the same and no CEL. . The drip pan (pcv) and the caps has been replaced last year (Wasn't leaking). So I removed the secondary air pump and left side check valve with a couple air hoses then put some JB plastic weld and add a thin metal plate for extra strength. Its been working fine. If this brake again later, will replace the manifold. I just wanted to see how long it can handle..... Btw, the best video on the TH-cam. RESPECT !!!
Y J,
Thanks for your kind words. I'm in Japan at the moment and want to take my time reply to you. I'll be back home next week to turn around going to Europe for six weeks and with me grand kids come to US for summer.
In the mean time if you have a question please don't hesitate call and ask for Nathan.
The number is at the front of the video.

I would love to see this on a MB 273 V8. GL450. Plenty video's on the six cylinder M272 but not too many or ANY on the M273. I know the procedure is close on both but it would be nice too see the M273 V8 Thank you again.
Thank you for watching and leaving comments.
Exactly the same. Doing my 08 right now. Complete fuel injector, ignition, and air handling rebuild. Not cheap..
Excellent Job. Thank you for explaining those little Gray Clips that are always a pain. I'm on Long island and I see you mentioned October, Will you be coming here to Long Island? I would love for you to do this job on my truck. This is the Best video I have seen great JOB!! Thank you.

Great video really helpful!
This is GREAT....now I hope I never have to do this!!
It's like watching someone playing with a plate of spaghetti.
This is nothing. You ain't seen nothing yet.
How can I be sure I am disconnecting the engine side of the computer and not the computer side?
It is clearly shown in the video. The passenger side of the two plugs should be disconnected.
How many broken clips 😢 on my 2007 ml.and how to replace them
I just replaced my intake on my 2007 c230. It runs great but I have p2015 code for some reason. I have double checked the flaps and nothing is broken. What do you think that could be?
Robbie, unfortunately, it is hard to say without having the car. Good luck.
I have the same problem, i bought an aftermarket intake. I get the code p2015.... position sensor switch circuit range and also p0410 in current but also pending and check light turn on, wonder if i should keep driving it till it adjust.
@@roquesosa87 Again, it is hard to make a comment without seeing the car.
Good luck!
Hello, i replaced the intake manifold and now i have p0106 intake manifold pressure sensor malfunction, i changed the sensor for a oem one and the vacum hose to it. And im still getting the code. I have 5v and ground in the connetor. Any idea what it could be ?
Check your work again.
Hi what is the symptoms to replace the inlet manifold
The car had no good acceleration and if i hit the fuel pedal suddenly it won't shift to next gear till i remove my foot and when need to stop so hit the breaks it will gradually down shift with feeling to the all shifts
Is that the because the intake??
My friend go back and carefully watch the video. Everything is explained.
Thanks for this video - it's really going to help when I attempt this. One question though, would you recommend swapping the plastic tumbler flap actuator on the front of the brand new manifold with one of those billet aluminum ones from AGA or URO, so that the possibility of it breaking in the future is basically zero? I'm in two minds as I read that Mercedes specified the tumble flap actuator to be plastic so it would break before the actuator flaps inside the manifold itself...
Law boy, others have asked this question too. My reply is NO. It is like taking a 10 Amp fuse and replacing the wire bridge with a heavy-duty wire that can efficiently conduct a 200 Amp current. Is this smart or what?
@@mbhmercedes-benz7822 idiotic, that same shitty plastic part is going to break AGAIN very soon. Many have replaced with aluminum and had no problems.. why would you replace the entire manifold with the same faulty part lmao
進氣岐管故障，會導致跳檔不順甚至入r檔熄火嗎
Dear friend, in case of failure of the intake manifold the gear shifter seem to be at the higher gear and feels like you have to downshift or feels like the fuel is very lean.🤥
On my 2007 C280, I get the P0206 code. removed the intake manifold, but none of the rods are broken, and testing with a vacuum testor, all the actuators function. Thoughts as to why I'm getting the code ?
I have to see the car and scan it with Mercedes scanner.
I am replacing the manifold. Should I be lubricating any of the internal flaps before installing. If so with what?
No sir you don't. Just follow the video.
Good afternoon i need to replace my intake manifold on my Mercedes C320 W203 year 2001 ,i believe it is on the right side under in , what type of time frame would i be looking at Mercedes Dealer believe a little under 4 hours ??
thanks for your help much appereciated ...
You are looking at M112 engine on a 2001 C320. It is a different engine than this one. The time it takes you to do the job depends on how skillful and experienced you are Unless you are a “mechanic” and want to know what the book allows for this job.
Hello guys. A little help please(P2006 - no check engine light,though ) It doesn't look like anything is damaged with me, but after pressing one of the levers as you do in the clip, it stays in the same position and does not return.,at the same time it moves hard. What do you think the problem might be? 🙄
Just replace the manifold. It means the flaps are stuck in carbon buildup/Sludge.
They sell upgraded manifolds with better made pieces
Great vid.. you are the first person i've seen that didn't undo the connectors at the coilpacks. Very efficient stuff! Getting ready to do this on my m273 is it pretty much the same job? I was wondering what size and brand vacuum hose you used for those lines you replaced (or did you buy the oem replacements?) and where the other end of the one you cut goes. Also are most of these bolts the same size? I dunno how you were able to keep track of all of them like that. Lastly did you buy a new gasket for the throttle body or did it come with one? And... last lastly why do you not recommend disconnecting the battery?
The vacuum hose is 3.5 mm on the inside (ID) and about 8 mm on the outside (OD). Main concern is ID to be 3.5 mm.
Not all engines have the same vacuum hoses. The small V6 engines that do not produce enough vacuum are equipped with addition Vacuum Pum on the back of the driver's side camshaft. There is a hose that goes from the vacuum pump to the area behind the fan that gets connected to grill. Not to get confuse 95% of engines do not have this vacuum hose. Just check your car and see what you have, and replace it.
We replace the throttle body gasket unless it is in a good shape and relatively new due to reasons.
If you disconnect the battery you then have to reset some of the memorized items. We want to be as efficient as possible. It comes from years of teaching engineering and not plugging the values { such as ( m/Sec.) (m/sec.2 ) (Lb/inch2) ( g/cm3) (g/L) etc. } unless needed. If you are an engineer, you would understand.
In my 2008 SLK280 R171, I have confirmed the broken plastic part with an inspection camera. However, no CEL, but the code is p2006. How much should I expect to pay at an independent mechanic to fix it? Should I just replace the broken part or the whole manifold?
if its the original 2008 manifold, i'd suggest changing the whole manifold. especially if the lights been on for a long time
We have discussed this matter several times in this comment section. Again I suggest replacing the the old intake manifold.
The labor should be 4 hours plus materials and taxes.
Were did you bought the intake manifold flat kit from please? I need it for mines been looking for it where to buy it. Mercedes-Benz doesn’t sell the kit so the whole set I don’t need the whole manifold set. I just need the kit.
We sell them. Where are you?
Great video thank you. What’s your opinion on just taking it off to clean all the dirt and oil? Will it make it last way longer? What do you think about swapping for newer intake from updated engine model (plastic one)? I know you just need to code your ECU
Cesar, there are two sides to me. I am an Ex professor of Mechanical Engineering (Fluid, Thermal, and Robotics) that was not careful and my hobby became my business against my wishes. Now I am also a "shop owner" in which I used to be the only mechanic. I have awesome guys working with me nowadays.
When I am working on a customer's car I am concerned about correct diagnosis and fixing the real problem (not my imaginary), correctly just like new or better.
My customers, just about all of them want to know, How much and how soon. Nobody asks how. But once the car is picked up, they expect it to function longer than the original unit. If I save them 20% on cost or engine efficiency, for the most, they do not care. They just want a reliable car.
Working on my own car is a completely different ball game. When I was younger (I am 66 now) I would spend hours more on repair saying I saved a penny, however, I was reducing the reliability and would not count my valuable time. Now that I am older, can not afford to have car problems on the 600-1000 mile trips and do not care to carry my toolbox with me.
Everything that you said is doable but you expose yourself to more potential problems. The intake will not last "way longer" unless you come up with a different and better design.
Where are you? Thank you for taking the time and writing to me. I started playing with Mercedes as a hobby and now am back to the hobby and making videos. LOVE IT.
That was my 2Cents.
@@mbhmercedes-benz7822 thank you for taking time to replay really appreciate. I’m still in that first phase of life in which you want to learn as much you can, you think have time to waste and money to save, but above all, I do appreciate the advise of people with more experience than me. I’m based in Wisconsin, if you happen to be around I’ll happily invite you a beer. Looking fwd to see more videos I really like how you explain things.
Did you disconnect the battery before you started this job???? I took the day off tomorrow and I’m gonna attempt to replace my intake manifold I’m a mason by trade so I’m worried about me pulling on clips to hard
Jason,
Leave the battery connected. make sure you have new vacuum hoses to replace the worn ones. Be patient, do not rush. Try to be easy on plugs, do not pull them by wire. Clean the areas as per the video. Watch the entire video couple of times and make notes. Get a friend to watch you and give you a hand if you needed help. JUST follow the video. Keep me posted.
@@mbhmercedes-benz7822 Why do you recommend leaving the battery connected?
Do you ever replace the plastic levers on the stock manifold with the aftermarket metal one? I ask because I am now getting a p2004 code which indicates a broken lever a year after replacing the manifold
Wayne, my friend, Victor Gonzalez asked the same question below and I answered him. Here is my answer:
Victor, when a fuse blows, it is an indication of an internal problem and you do not replace the fuse with heavy-duty wire. The weak link of the intake breaks due to an internal problem with the intake manifold and Mercedes-Benz recommends it be replaced with a complete intake manifold. As a business, you can not afford to cut corners.
When you perform these jobs as a business, it is one thing, but when you do it as a hobby, you do not have to worry about losing a customer or possibly a lawsuit.
With the knowledge that I have nowadays, I would do the same thing even in my own car but 40 years ago, I probably would have taken the shortcut. Maybe not.
That's insane! Sorry to hear that. Did you do it yourself &/or use a Pierburg one? I'm trying to decide if I should upgrade mine before I install it, or if it's even an "upgrade" at all. As hinted at in the shops comment, it could just ensure internal failure rather than external failure. Bye bye valves.
@@RothBeyondTheGrave I am confused. Are you asking a question, making a comment, or what? Don't get excited, calm down and then write.
@@mbhmercedes-benz7822 there is absolutely nothing remotely confusing about my post. It was a direct response to the o.p. which stated his new manifold failed after a yr, which is pathetic.
I inquired about the part itself (if it was the pierburg unit or another one), if he did the job himself or not, etc.
I also wondered if I should "upgrade" to the external aluminium piece before installing my new manifold (which I didn't).
I also mentioned that I saw you suggest fitting the aluminum external piece is not a good idea, as it was purposely made to be the weakest link in the system. Theoretically, upgrading that cheap plastic garbage on the front could put extra stress on the internal cheap plastic garbage, causing an internal failure which could (and has in other failures I've read) break off & damage/destroy a few valves.
That's the long winded version. I'm not sure how that wasn't clear.
@@RothBeyondTheGrave Bingo.....You got it. Good job!
What Size bolts did you use to align the Intake manifold? (2007 GL450, V8). As I would like to do the Same. Thank you for a great and Helpful Video A++++.
Same bolts as intake manifold or possibly 5mm longer but you cut the top off.
@@mbhmercedes-benz7822 what is the bolt diameter?
I'm in the process of replacing mine. Got the old one out. The code I had was p2004 but nothing seems broken, everything is in its place. Any idea?
Sorry, I can not say what is or was bad without looking at it.
Hello, have you been able to do anything to your car? I have p2004, too (no check engine light, though). Car is generally ok but a little slow at lower rpm. I am afraid to open it up and find everything intact. This is not an easy job
Apart from the code, what symptoms does your car show?
@@David-el6hh tumbler on mine broke. noticed at low rpm car would not accelerate prperly until high speeds
@gjoniny1534 Have you replaced it? Is there any noticeable improvement after?
Great job on the video. Saw another where the plenum had to be tapped for the bolts. You think the new part would come with a better design or upgraded parts that wont break in 70 thousand miles. I have to do mine but I'm going for the replacement rod and aluminum upgrade instead of a 700 dollar plenum. But like i said awesome job on the video but there is a replacement upgrade for the broken parts check rock auto
Good luck with the repairs.
What did you use to clean the fuel injectors?
Würth parts cleaner.
I have to change the intake manifold on my 2011 E350 and your video is a great tutorial. One question I have is that the vacuum line that is in the front of the intake manifold was replaced by the tech because the original one was worn...what size vacuum line did you use for this? Thanks

@@Abadani Hi, I am from northern Italy ;)
How long should this take on 2010 ML550?
I don't know. It depends on you and your experiences and skills. Under 5 hours is good.
I get the weakest link for a reason on other replies I guess its a chance we take but if your doing it by the book there is no cutting corners
When in business, you are not to cut corners. For your personal car you can do anything and not to worry but not on customer's car.
Are you in VA Beach? can you recommend a mechanic in the NYC/NJ area?
Michael, sorry for delay in replying, was travelling in Japan and Europe for couple of months. I am in VA beach. Give me your zip code? How far are you from Long Island? Can you wait till October or about?
So I didn’t understand you very well do you have to tap and drag them yourself or does the boat do it for you because when you start at the actuator needed to be tapped in threaded you were implying that you had to do it yourself or did the bolts do that for you
The bolts are self tapping. They do it themselves.
@@mbhmercedes-benz7822 thank you I appreciate it
Why did you replaced the entire unit vs replacing the brocken plastic?
I would have replaced it too. But what I would have done was swap out the plastic lever for a steel or aluminum one & the linkages to aluminum as well. There's a kit on ebay that works to update the weak points on the manifold.
Maybe due to the internal of the manifold was gummed up
Victor, when a fuse blows, it is an indication of an internal problem and you do not replace the fuse with heavy-duty wire. The weak link of the intake breaks due to an internal problem with the intake manifold and Mercedes-Benz recommends it be replaced with a complete intake manifold.
