Took me weeks to put together all the data and months before I can release this video, it is a super important topic for any owner and to be owner of M272 and M273. Recently I have noticed a decline in viewers which is very disappointing and discouraging.
I am looking for this kind of videos for days now. You just made my day. Thank you so much, please keep going with you videos. you are talking very clear.
Thank you very much for all the job in this video. I've checked my M273 engine number and unfortunately it is affected. I have P0017 code only. Thought the timing chain replacing would help but now I see it doesn't make any sense. What a disaster. Gotta say goodbye to my beloved CLS. Hopeless.
@@BenzAddiction I have replaced all 4 sensors + adjusters. P0017 code still present. The engine cranks slowly but once started it runs nice and smooth, no odd noise at all. I am bit confused now. I'll give it one more chance, go to a garage and try to repair it. Will let you know guys whether it's fixed or not and how much is it in UK.
I really like and appreciate all your videos and effort in making them. I know it can be hard reaching all your targeted people/ groups sometimes, but quality content and calm methodic instruction like you provide is priceless for MB enthusiasts like me/us. I hope you prevail and find energy in continuing your great Chanel on RUclips, we need people like yourself to teach and educate the Mercedes fan community. Cheers Mate💪
Great work Max..this is why I like the M112 and M113 engined cars like in your CLK..and why I stick with my CLK55..even though it is nearly 20 years old and only has a five speed trans. Sorry to hear your views have dropped ,,personally I like the CLK videos and the SL , not so much the older W124 , but I do think all your videos are very well done , clear and very good advice for MB owners ..don't give up and I am sure you will be successful.
@Leo555ZZZ Thanks Leo for your feedback, I am trying to keep the variety for most of the subscribers and viewers :) M113 especially the AMG version is great 👍
Great detail of step by step! Your Star Diagnosis needs to connect to the Internet to work or you purchased the standalone version? I was debating if i need it because i already have Autel & other bi-directional scanner.
i have a later m272 on a 2011 e350 4matic, have rough idle where i feel vibrating in the cabin, any suggestions as to what it could be? I have changed the transmission fluid and filter, changed the MAF, changed sparks and changed a bad coil and still nothing
1. connect a scanner and check for codes. 2. most simple checks are make sure maf is seated properly. it is easy to not put it back into position properly and you will experience rough idle. 3. make sure all hoses and electrical connections are connected appropriately and not damaged. 4. worst offender is engine mounts which do not last long. my mounts engine did not move much but when i replaced them, the drivers side was split in half. i experienced terrible vibration. you won't know the mounts condition until you remove them.
I was looking at a 2006 c280 125k miles and drove it home and got cam shaft position sensor p0015 code, car drove completely normal in my opinion and sounds fine. I looked up the engine and it is one that has issues. Does it just have a bad sensor cuz you didn’t say anything about this code. WDBRF54H36A850841 is the vin.
I have googled this today: Is it all true? The M272 uses balance shaft. But! The Mercedes-Benz M273 V8 engine uses an idler sprocket, not a balance shaft. The M273 engine is inherently balanced, so it doesn't require a balance shaft. Instead, it has a timing chain idler sprocket, which is a simple "dead idler" bolted to the front of the engine. May it be easier to repair - idler sprocket vs balance shaft?
True: Yes, the M273 Mercedes engine, like the M272, is susceptible to a balance shaft sprocket problem. * M272: Experiences balance shaft sprocket wear and tear. * M273: Experiences idler gear sprocket wear and tear. The Issue: * Premature Wear: Both engines have issues with the balance shaft (M272) or idler gear (M273) sprockets wearing down prematurely. * Timing Chain Slack: This wear leads to excessive slack in the timing chain. * Camshaft Misalignment: The timing chain tensioner can compensate for some slack, but eventually, this leads to misalignment of the right-bank camshafts. * Engine Malfunction: This misalignment results in rough running, check engine lights, and potential engine damage. Symptoms: * Check Engine Light * Rough Idle * Reduced Engine Power * Misfires Resolution: * Repair: Requires engine removal and replacement of the worn sprocket(s), along with other recommended components per Mercedes Service Bulletin S-B-03.30/08i. * Costly Repair: This is a significant repair, often exceeding $3,000. Important Note: * This issue primarily affects earlier production models (generally 2004-2008). * Mercedes has addressed this issue with improved sprocket materials in later production models. Disclaimer: This information is for general knowledge and guidance only. Consult with a qualified Mercedes-Benz mechanic for accurate diagnosis and repair of your specific vehicle.
This can be done on an M273 without removing the engine (it's just a simple gear, for 272 you have to pull the engine out to replace and bolt the balancer shaft on both sides) , but you’ll need to lift it slightly as there’s almost no room to work especially when sealing the pan. A dealer would prolly charge around $3,000, but you could probably do it yourself for $500 or so (I did it a while back, but I don’t remember the exact cost, chain kit + guides + tensioner + different gaskets etc... ). Be warned-it’s extremely time-consuming. Don't even try without the WIS aside to check for the right procedures along the way, and get the chain + guides + tensioner replaced while you're at it. If you don't want to bother, pull the engine out it's still MUCH simpler...
My C300 is 2009, just to clarify balance wouldn’t be a problem in this model? Some common issues I’ve already fixed at 105,000 miles- Idler pulleys and tensioner Oil cooler and air filter housing replaced Regular transmission services Oil changed every 4500 Vent valve every 50,000 as preventative And I recently replaced intake manifold Any other issues I should look out for in the model year? Ik can magnets can cause issues but isn’t about anything else
Hi there, we have a 2011 E350, terrible vibration over 2500 rpm, only 123kms.... the Vin/Chasis number is WDD2122562A477695, I cannot find the engine number, I have tried to find out pressing the telephone and Ok buttons but cannot access the system, can you help ?
Hi max i hope your day is going well i love your content. I just picked up a clk550 with the m273. I test drove it it drove very well. At first it took a while to crank, but it would start, now it takes a while to crank starts and then shuts off almost immediately. Any idea or help
@@BenzAddiction Thank you max, I love your content you shouldn't feel discouraged your content is top tier very clear and concise and you also talk back to the community:)
Really nice videos Im intersted in ml class 350 2011 Recently almost everytime when i start my car only in the morning after 5-10 seconds all my warning lights go on and iam unable to put the car into gear I know about ISM faults but it only shows this problem in the morning I also got a video of it,if i can contact you somewere so u can give me an advice id really appreciate that😊
@johntarenidis9338 If you are asking me what I did to that car, I actually ended up selling that ML350 and bought another one (2010 ML350 with 100k km on clock) as I did not have time nor physical stamina to pull that engine alone.

Can you do a video on replacing the balance shaft sprocket , I like how you explained step by step. Thanks
@erick3786 i will do at some point but unfortunately it can not be anytime soon as we are moving to a new property, which gives me a bigger space.
Great videos! Did you disconnect the negative battery terminal prior to replacing the sensors?
No, not required disconnecting - terminal on a Mercedes-Benz has its own risks, even if it is less than 1 percent:)
Great detail of step by step! Your Star Diagnosis needs to connect to the Internet to work or you purchased the standalone version? I was debating if i need it because i already have Autel & other bi-directional scanner.
@Brian_L_5168 Hi, Brian, thank you. It is a Chinese version and not connected. But still provides great info of the depth of the issue.
if your sensors are good but you are experiencing leaks from the sensors, you can buy the OEM seals/orings from the dealer for $5-9/each

Stop throwing money and Diagnose using a proper scanner, come back here with a code and we can help you to get in to depth of it.
1. connect a scanner and check for codes.
2. most simple checks are make sure maf is seated properly. it is easy to not put it back into position properly and you will experience rough idle.

@Rvssvlle90 probably a bad balance shaft sprocket causing a chain slack. With that year and mileage, it's not unlikely at all.

Some common issues I’ve already fixed at 105,000 miles-
Idler pulleys and tensioner

Yes, great, check the differential oil too.
