OK, as a shop that does this job properly quite often I can assure you that that is a temporary, short-lived, maybe fix. It will only work if the chain is stretched enough by one tooth. Also the chain will keep stretching to the point it breaks. However if you were a backyard guy doing it for yourself you could probably buy a year out of that fix. Unfortunately I have to answer to people. So it’s better to charge the $6000 and fix it right once. But like I said. This fixes fine if you’re doing it yourself as a hobby with a customer is aware it’s going to be temporary.
Hello, do you still see any M272 engines that are past the affected range (have the improved balance shaft) come into the shop with P0016 and P0017 codes? If so, are they usually due to stretched chains? Thanks
@@mascho22 , @stevepitbull: I have the same exact question. My car is far out of the affected zone; it has no symptom whatsoever. I think it could be a variety of reasons other than timing chain (such as cam phaser, cam plunger, oil sludge, etc)? Any thought or cure for your problem yet, Michael?
@@petediegan2794 Yeah sadly the cure was to replace the cylinder head and cams. Took off valve cover to find Intake cam was broken in half due to oil starvation near the front half due to excess sludge blocking crucial passageways. The rest of the engine survived fortunately so got it running good finally after a lengthy process
yes works had a old mercedes with this problem repair out priced value of car well just the parts did that ! customer approved me doing this as just a paper weight sitting on his drive , thankyou
Hi, thank you for posting this video as it looks like I might have to do this. I wonder if I could get your opinion on this, my car just started to start up slower than usual and whilst driving it felt like it would cut out but then it would come straight back on, I plugged it into a diagnostic machine and there are a lot of codes but the ones I want to know about are these: p0335 and p0336 which are the cam and crankshaft sensors I also have the dreaded p0016 and P0017. My question is do you think that the faulty cam and crankshaft sensors P0336 and P0335 could be the reason I also have the p0016 or P0017 error codes? Or do you think that it’s something else? Do you think if I replace the cam and crankshaft sensors that all the codes will go away or will it only erase the p0335 and p0336 codes? Any help would be much appreciated, Many thanks
Hello, thanks for a great video. However, I am ready to rip my hair out as I have been attempting this repair for a few weeks straight. Once I put everything back together and view it through the front cover @ 305 degrees (55 degrees past top dead center), I am unable to get the passenger side (right side) to line up perfectly. The Left side continues to be perfectly aligned but the right side has either been under rotated or over rotated as I have tried this several times over. It seems impossible to get the timing to align perfectly on the right side. Also, when I put everything back together and start up the engine, I am able to clear the codes but they come back every other time I start the engine. (The different P0016 and P0017 codes). Again, while I can get them to clear, they just come back every other restart. This has me thinking that its because I cannot get the engine precisely timed so like I said, I tear everything back down again and try one more chain link further on the Intake cam and the engine is over rotated at the 305, or 1 more chain link less on the intake cam and the engine is under rotated at the 305 mark...... of course I view this once everything is put back together so it is absolutely maddening as it is way too much work to redo this each and every time and keep getting these same result..... too much or not enough. Do you have any advice here? Please help ASAP!!!!
If the gear is off alignment too much that mean the middle balancer shaft is worn out or the guides are worn too . So what you have to do now is to open valve cover make a visual inspection to the guids if one of them broken and check if the teeth of the balancer is damage . after check the crank with 40° and see both cam suppose to be aligned with the surface of the head
@@hafidautorepair2793 I appreciate the response. I do in fact have the valve cover removed as I have done each time. I also attempt to line up the markings on the cam gear @ 40 degrees each time. I have only been able to remove the outer most guide rail for inspection and to reposition chain. Unfortunately, the inner guide rail had threads broken off inside of it while attempting to pull it during my initial repair effort. Therefor I have been unable to inspect this rail or the teeth of the balance shaft which would be viewable upon its removal. Now I suppose that I am faced with putting the engine back together and letting it be or trying other methods of rail pin removal. The engine seemed to run fine when I last put it back together but again, the light just comes back on. Any advice?
@@hafidautorepair2793 I think that is what I will do, thanks a million brother for all of your help! You have brought me a great deal of peace on this matter. Worse possible case is that down the road something goes wrong and then I can just buy a used engine at which time I could just do the proper balance shaft repair before installation. God bless you good sir!
When the chain stretch a little of course the tensioner come out more a little bit too . But dosen't matter if you don't want to replaced is ok too . And about the tork if you don't have tork wrench torked till stop no tied too much
Hello sir I'm having same code p0016 on 2014 Mercedes Gl450 magic. Does this video apply? I have replaced sensors and cleaned the connector, as I noticed oil. Your help is greatly appreciated
GREAT VIDEO, LIKE GOLD, THANKS SO MUCH, ONE QUESTION MY FRIEND, I HAVE THE SAME CAR WITH CODE p0452 tank pressure sensor, the question is!!! WHERE IS THAT SENSOR LOCATED??? SO I CAN REPLACE IT, AGAIN THANKS FOR YOUR VIDEO, I HOPE YOU CAN HELP ME OUT WITH THAT QUESTION
Thanks for your reply, unfortunately I open both passengers and drivers side, and is not in any of them, thanks, please let me know if you find anything
Hello. I have a W221 S550 (M273) and the check light is on. Logs P0016 and P0017 errors on ignition and they stay for a long time. Sometimes the check light goes out by itself and comes back on after a while. With live data, there are no errors and all indicators are normal. I decided to manually check the shaft marks as in your video, except on the M273 the shaft should be at 305 degrees. All 4 marks are in the center of the holes. That is, the circuit is in good condition. I have absolutely no problems with the car. The engine works great. Is it possible that the sensors have screwed up and are indemnifying for these errors?
Try to swap the sensors 1st . If the problem stay the same , make sure the oil level is good too because if less the chane tensioner will not push the chain guide good
@@hafidautorepair2793 These days I'll swap the location of the magnets with the ones on the right. And is it possible at the moment if these magnets are defective that they confuse the ECU and cause other problems?
My engine runs good and no Leaks but I do have an engine light on ..cam shaft cranking correlation sensor A&B are indicating note I have no leaks and th engine starts smooth do I have an expensive repair or just a minor thing It’s a Mercedes e350 2010 OBD (P0016,P0017,P2422)
U are the man I have the same problem with my 06 Mercedes Benz e350 but they guy said said it's just the timing chain are u sure it's the camshaft balancer as well ?
@@hafidautorepair2793 Hello, do you see any of the M272 engines that are past the affected range (have the improved balance shaft - 2008 and newer) come into the shop with P0016 and P0017 codes? If so, are they usually due to stretched chains or maybe bad cam position sensors? Thanks
@@mascho22 yes till 2010 they still have the same problem because of the balancer shaft get worn . And later on the chain guides get damage too who makes the chain get loose more
Your the man bro... i am going to try this first, but is it possible to change the gear of the balance shaft instead of changing the whole balance shaft? Just an idea i have so i can avoid pulling the engine out just to hold the back weight in place. Is it possible to change just the gear/sprocket?
@@hafidautorepair2793 i have the c350 3.5l engine. And to change the gear by itself i was thinking of stripping the whole front of the car. Still easier then pulling the engine out and apart from the trans.
Nice video, but.... brother, come on, just replace the chain and the cam adjusters. If does cost $4,000, 5,000, 3,000, you can give warranty and this is the job. This is so temporary, i just wonder how long you tell to customers is gonna last. Sorry for that comment, you have all my respect any way.
Thanks for this question , absolutely this is a temporary job it may drive till 40 to 50k . and if the balancer shaft is too much worn out, it may not fix the intake camshaft p0016 code .
@@hafidautorepair2793 , so should we clear the codes every day? Or it doesn't matter if one clear the codes or not, they will have random misfires anyway?
Hello again: My 2008 e350 has bank 2 misfires, all 3 cyl. I believe has a broken intake camshaft adjuster (bank 2 drivers side) because the cam when holding it from the back does not move when I turn the crankshaft even though you can see it turn from the front looking through cam magnet hole. What are the steps to remove and replace? After removing chain tensioner do I have to remove the guide also to get enough slack in chain to remove the gear? Tks
First you have to know what shaft is broken Intake or exhaust one . If exhaust shaft is broken that very easy . If the intake one who is broken you have to remove both valves and put the timing Mark's then remove tensioner and remove the guid pin on passenger side to remove the intake gear and loose chain if . Just make sure to marke the chain with guirewith a good marker
@@hafidautorepair2793 Ok so after setting timing marks to 40 deg and removing tensioner, removing just the guide pins alone (not the guide) on passenger side will give enough slack in chain to remove intake cam gear on the drivers side? Is it possible to email you direct for a couple additional questions? Thanks!
You are not supposed to rotate the engine while the valve cover is off for the M272 and M273 engines. The cover serves as bearing caps for the camshafts, which is why there is a specific order and torque sequence for this cover. If you do this, you risk damaging your camshafts and your engine not running properly. The engine should be placed in 40dg past tdc prior to removing the cover, and it should not be rotated after it is removed until you have properly reattached the cover. This will ruin people's engines if they do what you propose.
@@carsusa1 the chain can be done in the car, but is much easier to do out. The bigger issue is that those years 2006-2008 (up to a specific engine#) M272 timing codes typically come from a worn balance shaft, which really requires the engine to be out. The balance shaft was made of a lower grade material than later engines, and is typically worn. There are lots of videos of that problem along with the fix, which is quite extensive.
What part of California you are? Where is your shop? I got a 2006 C280 4matic with the same problem P0016 and P0017. How much do you charge to do this repair?
I took my 2008 ml350 apart and the timing marks are dead on but has this code any ideas, replaced the sensors before doing this.And code came back after driving.
master auto apatchi master auto apatchi Great, thank you for your reply. Just one more thing please once I’ve readjusted everything and have to tighten the two gear bolts back up how tight should they be? do I need a torque ratchet or do I just tighten them has much as I can?

Master auto Apatchi, can you recommend someone who can fix my car in Pittsburgh Pennsylvania? I have a 2010 Mercedes Benz GLK350 4Matic with the same codes of P0016/P0017
I enjoyed your video . My code is just P0017, it reads “Constant adjustment of outlet camshaft of the right cylinder bank in Retarded direction (P0017) Do you have a video that show how to correct that problem? Please advise. Thank you!
hello i watch your videos often i own mercedes e 350 cgi 2009 (petrol) my engine light has been on for some time error code p1208, p0016, p0172, p0746, there are no real symptoms on the car other than Blackened exhaust plus passenger side and sometimes misfiring when starting up when the car has cooled down a bit to 70/80 degrees, the timing is correct, the camshaft and phase shift sensors have been checked . Do you think this could be a phase shift disc and if so which one? Exhaust or intake? Thank you very much, if you could answer me i would be happy
Honestly you have different codes and different ways timing code and system rich or lean and transmission codes . So you have to start from one of them first and go to the next one
I have a 2006 R350 with these error codes and it won’t start. The engine tries to start but won’t turn over. Will this prevent the vehicle from starting, or is there something else you suggest needs to be done?
Hi! If that problem happened, I guess it will not go away so easy. If the chain is stretched, or balancer sprocket is worn, it should come again very fast. What do You think? I have changed chain and balancer 6 years ago, around 100k km ago, and it is now same problem again. I would consider Your method, but how long will it last? My engine is V8 M273 2007.
@@hafidautorepair2793 Like an old man. I have 3 small kids, so I'm very gentle. It is interesting how it has worn new sprocket or chain in few years, while I was driving below 3000rpm all the time.

HALLO! I have a Mercedes e280 2006 gasoline and the p2090 y49 / 7 (right camshaft exhaust solenoid ) diagnostics, the engine light is on. When the car is cold and ignites the engine, heavy sound is heard for a few seconds and then gains quietness. I pass the solenoid sensor and the motor chain tensioner and as a result the cold flashing noise is easier, diagnosis with p 2090 displays component y49 / 7( right camshaft exhaust solenoid ) has short circuit to grund,And the engine light returns. With your experience you can tell me why this is happening and what can I do. RESPECT
Hi master auto apatchi, I’ve rotated the crankshaft to 305 degrees and can see both logos in the center of each cam position hole, they are not in the exact same position but they are both visible within each hole, can I send you the pics somehow to see what you think? Or is there a way to share them on here?
I have a 2000 s500 that for no apparent reason will not turn on. windows and seats work fine only if the door is opened. There are other things that do not work .
If you replace the balancer shaft and you put the chain on the right position you have to. Check which one still gives you advance or retard and programe the computer to new position of the camshaft . because the old adaptation still on the memory of the computer
@@hafidautorepair2793 my timing alignment are perfect .does the cam shafts vvt issue could give the same error code or not. I will do the adaptation and check that .thanks for your help.

I have a 2007 C230 m272 engine, supposedly past the balance shaft issue but I have this persistent P0016 code only. I tried swapping the intake and exhaust cam + crank position sensor/magnets but still get the same code. I do experience loss of power on the freeway and going upills. Balance shaft? Timing? Stretched chain? Chain guide? Tensioner? I don’t hear any slapping or slack of chains when started
the decided to use SOFT METALS to build moving engine parts. It turned out to be a perfect disaster then so now they use soft chains that need periodical replacement
The reason is a tooth off its because the BALANCER is bad, and needs to be replaced, it will jump a tooth again in the future.. to correct this problem without future issues you have to pull the motor out and replace the balancer! i cannot believe you`re showing this video and not explaining why it jumped a tooth, why its off?
YOU ARE COMPOUNDING THE PROBLEM WITH BUSH FIXES. your timing chain has stretched and you jumped right over that, and said all that i need to do is advance the Right side of the engine on the chain and all will be well, WELL NOT SO MUCH!!. you are introducing more length to the none-torsion side of the timing chain. This further extends the travel of the timing chain tensioner and you may be close to the extension limit. You have also with this concoction thrown the engine out of balance since you have disturbed the relationship of the engine moving mass compared to the effect of the counter-balancer. This action will cause more BACKLASH on a chain that is already compromised and cause further lengthening of the chain. I almost hate to say it but i do not believe in doing non approved fixes. Look at all work you have done to NOT FIX THE PROBLEM. With the correct special tools you can change the timing belt without taking apart the whole front timing chain cover.
@Tom A: you might be right, Tom. But at the same time, these M272 are mostly ten years old, more than 100K miles. MB doesn't have good and clear answers on these issues (I took mine to a dealership and their answers were worthless). Thus, a balance shaft for $9000 doesn't make any sense. A quick fix like this, if it could go another 30/50K miles is well worth it, don't you think?
@@petediegan2794 I don't envy your problem, Mercedes has the M272 engine with a history of chewing up the counterbalance sprocket. Your first problem is scope and spatial relationship. The timing chain when stretched affects the spatial relationship between the crank and cam. the computer notices this effect using position sensors. Even if you can trick the sync plates [in the camshaft] by advancing them to prevent the computer notification, you still have the problem that the valve action is not conforming to planned positioning which makes this engine crap even if it is still running. The other issue is that some of these engines [m272] cross 100,000 miles with no metal in the oil pan, and no pieces flying around in the oil. The [VIN] next to yours may be OK while you suffer all those repairs. my only recommendation is to buy a m272 engine from a crashed vehicle and if the engine is not fragmented with about 50.000 plus miles; with proper oil changes you can have a good, long lasting, replacement engine. It may surprise you how many M272 engines that are available for sale with 50 plus thousand miles in the salvage warehouses.
It's look like this mechanic never did this work.Hi is right, you don't need to replace camshaft adjusters. Never broke. The main problem inside engine - BALANCE SHAFT. Mercedes tries to save money all the time and don't care about our pocket. In 2006 and 2007 years they put very bad quality balance shaft. As result chain destroys balance shaft. Right side camshafts late by wrong chain position on balance shaft. Computer can't adjust this problem and turns "check engine ON ". For proper repair engine or transmission must be taking out. Balance shaft bolt located in the back of engine. Engine generation M272. Check my post with explanation and pictures.
I'm putting this video to help the technician to fix the problem without replacing the chain, balancer shaft ,guids and the tensioner . And you know this parts and labor how much will cost if you are a mechanic (some shops they charge $4500 or $5000) .

@@hafidautorepair2793 I mean Japanese vehicles are far more reliable. This is a common fault with Mercs and cost a lot to repair. You have done a good job fixing it, but for average home mechanic this is almost impossible to do.
