A friend reported that her 2012 CLS550 with 90,000 miles on it started to display the "Check Engine Light". She said she experienced no other symptoms. The Mercedes dealership said she needed to: REPLACE ALL CAMSHAFT SENSORS ALL CAM MAGNETS ALL O2 SENSORS ALL INJECTORS (CHECK ENGINE) at a cost of $7,220. Also, the dealership wanted to REPLACE ENGINE WIRING HARNESS (CHECK ENGINE) for a cost of $6,075, REPLACE ME CONTROL UNIT (CHECK ENGINE LIGHT) for $1,175.00, and 3.00HRS TO REMOVE SPARK PLUGS AND INSPECT PISTONS FOR OIL INCURSION . (CHECK ENGINE). A paltry $489.69. But wait, there's more. Much, much more. As an added bonus she gets a complimentary car wash, vacuum, and tire shine. Such a deal.

What a great little side tip you gave around 9:06 - "Always put these back in by hand. Don't try to put them by a socket, you can cross thread. If you don't feel it with your hands you won't know what you're doing so put them in by hand, turn them by hand, go as far as you can"

I know this video been out for a while, but I caught at 7:04, you said it really bothered you that they did not put the bolt back in. Someone may have pointed that out, but I did not read all 438 comments. You took that bolt out when you did the first sensor removal (which was the bolt you were referring to being missing). Great video.

Best step by step ive seen so far for the sensors

You are very good in that,God continues giving knowledge to share with all of us...thank you.....God bless you.

Like the videos my friend. I took my camshaft position sensors out and rotated the crankshaft to 305degrees. Luckily, balance shaft is good! The circles inside the cam sensor housing lined up perfectly

Hello from Cancun, excellent video! I have a doubt, did you actually replace the parts? Because it seems like you clean both parts, replace the O-Rings and gasket and put them back. If you did that, when you do that and when you need to replace the hole parts?

The video was well done. Thanks for sharing your knowledge. I however would like to clarify some information. The item you replaced is not called a gasket, it’s called an “O” ring. And “O” ring you replaced on what you called the magnet sensor is incorrect, it’s a VVT solenoid (variable valve timing solenoid). It controls the oil control valve.

Another fantastic video with quality description with procedures!!!

Thank you, for the excellent quality of procedures in replacing the camshaft & crankshaft sensors .

Correct torque for those small bolts is: 8 Nm = 6 Ft/Lbs, please, dont give people wrong info, those little bolts cant take 10 ft/lbs !!!! Thank you !

Good video. Any link for the O rings, small and large ones?

YOU ARE AWESOME! I just finished reading a long 15 page thread on MBWorld Forums. Watching you do this has made my day! NOW, i gotta order the magnets

Very clear explanation. Like how you replace the o-ring rather than replace the whole sensor.

My 2007 S550 has been having problems starting for the past 2 weeks. I changed the 2 passenger side Cam shaft magnets which was the easiest and changed the crankshaft sensor. The car cranked but only after unplugging both batteries. After driving home and letting the car sit for 4 hours, I tried to crank it but it did not crank immediately but it did turn over and eventually cranked. Perhaps I should have also changed all 4 cam position sensors? What do you think sir? I will change them tomorrow. Your video has simplified changing the cam position sensors. Awaiting your response.

New subscriber!! Thank you! My daughter recently picked up a 2000 s500 and it was cranking but not starting.. I will have a look at these connections and o-rings. Looking forward to checking out your other videos. Much Gratitude 🙏

Thanks for the excellent demonstration I have a problem with my 2012 ml350 I have changed the sensors 3 times but after driving it for awhile the reading and rough start comes back on position sensor bank 2 the only thing I have not changed is the magnetic one I am not sure what seems to be the problem

Did you perform the relearn procedure for the camshaft position sensor? I saw some videos for other vehicles where they used an expensive scanner to do the relearn. Do we need to do this relearn for an ML350 2011? The reason I am asking is because I took out the 2 camshaft position sensors and rotated the crankshaft to 305 degrees and found the 2 circles centered perfectly. However, I still got the dreaded P0017 code after I replaced all 4 sensors i.e., 2 new Bosch camshaft position sensors and 2 new Mercedes camshaft adjuster magnets on the passenger side. I don't know what is the issue that is causing the code to remain. Is there a possibility that one of the new sensors is not working?

Your an artist at your craft.

I love your videos. Good lighting and you take your time. Much appreciated

I really need the part number for the O Rings kit shown at 1:52 please? I'm struggling to find this kit listed anywhere (though I have a 5.5 SL 500 - though I think it's the same engine). Dealer wants to only sell all new sensors & as I only have a minor oil weapon, I only want to fix that & not introducing anything else / or calibration related requirements (should I replace sensors).

Do you have a part # for the bag of O rings? or where to buy them from as a set?

This guy has talent I want him working on my car!!!!!

That were very exciting ,to see your craftsmen repair and knowledge,which takes guesting the codes P0014 ,that I am going thru Thanks.

Excellent video as usual. What is your view on coating the 'O'-Rings in a thin coat of oil before seating them in place, I picked that up somewhere years ago. It is meant to prevent the 'O-Ring' from drying out and also to create a better seal. I am just an enthusiast amateur mechanic, not in your league, but I love to learn about the small details as they can make a lot of difference (like hand screwing in those bolts so as not to cross-thread the block, great tip!). I would love to know your take on this, I have liked, shared and subscribed, Top man!!!

Great job at explaining stuff! Please explain the IMRC position sensor & how to replace!

Excellent work, you’ve help me with several repairs on my r350. Thank you so much Cooper

Excellent video with great explanations. What is the part number for the magnetic camshaft sensor o rings please (large round parts in video)?

A very meticulous and helpful presentation. Thanks a bunch.

Great job (video) man... Keep up the good work. Just one question though; what is the blue thing that you put on the screws when you put them back in and what good does it do?

Great video and I will be changing those o rings as soon as they get them to me. MY PROBLEM: 2007 C230 Sport Crank and drive cut it off will not start for likely 24 hours. over and over same things, turns over fine but will not start. Stopped if for a week then back to the same thing.

Hi I’ve got code P0016 Status: Confirmed Possible decryptions (note control module): OBDII: Crankshaft position/camshaft position, bank 1 sensor A Changed the magnets but keep getting engine light for that code bank 1 sensor A. I even put the crankshaft on 305 degrees and looked trough the sensor holes and saw the circles are in center so I’m hoping my crankshaft it’s not off timing. My next thing is switching the sensors from bank 1 to bank 2 if I get same reading it’s not the sensors.. wish I did it before when I change the magnets it’s really hard to get the bank 2 the screws are behind the power steering pump. You showing the easy access site 😅 I had to unscrew the power steering reservoir and prime it risking to crack the plastic which holds in the pin but didn’t want to drain the power-steering fluid and remove it. Also need flat star E8 wrench to get behind especially the last 2 lower screws .. Could that be just bad sensor A?

Great video, thanks alot. I love watching all your videos. My 2007 ML350 shows check engine light ever since I bought the car and opened the fuel tank to fill gas. Do you think, opening a fuel tank caused check engine light? The error codes are related to camshaft. Do you think changing camshaft part/rubber will help to get rid of error? Please advise. Thanks

Dude you're the best

I have P0015 on my 2008 clk350. It says exhaust camshaft position timing over-retarde bank 1. Which is bank 1? Well, I guess you aren't checking youtube very often. I got a screenshot from somewhere that shows each code position. I got another 2008 clk350 for me, the other one is my wifes car. It has the same one leaking oil a little bit from the connector. It's a good thing it has the updated connector adapter to dip down, so it doesn't flow up the wire.

Not sure if you still read comments but, I've tried on this same side and my dipstick tube is in the way along with the other part of the wire harness, I unscrewed the front 8 torx screw for the dipstick but I can't move it out of the way, feels like I'm going to snap it if I try moving it to the left out of the way or pull it forward. Same with the wire harness to reach the bottom left torx screw on the front passenger camshaft magnet. And yes I removed the sensor before hand.

Great video. Thank you. I have question, or questions: after replacing those two parts, do I need to do anything else? The error is regarding the Bank 1 position etc etc. Will this take care of the Check engine bs? Or.....could be something else ? I’ve been reading nightmares even after replacing the sensors and magnets. Thank you.

Whats up . What sensor or magnet do i replace for a code P0025 on a 2006 c230 sport

Great explanation and great video Thank you for sharing knowledge

Thanks for your video and I was able to replace a camshaft sensor successfully. However, when I turn on an engine, I start to hear a high tone metal sounds from an engine for several seconds. The sounds stop but 10 minutes later, I heard the same sound a few seconds. Now the ideal is about 800 rpm and a bit higher before the replacement. Is this alright?

Excellent work!

Excellent work 👏

Good Job!

On my C280 year 2007, had an engine light on from consistent camshafts adjustable. Should I replace any magnet?

Well I want to thank you so much.

7:01 - Isn't that the bolt that you removed initially to take out the position sensor? (At 3:22) Fantastic video though. The ECL came on in my stupid E550, different codes but they refer to the position sensor so I'm going to use this to guide me through changing it.

Thank you for the video. Question, how did you get the fourth one behind the power steering fluid? I'm a weekend warrior so didn't want to mess anything up! Wish that was in the vid!

hey the job are you doing on mercedes i just learns i need to do this in my car thank you so much i like your show is really good

Great instructions , would you please tell me which part is related to P0016 in a 2007 C230 Sports model . Thanks

thank you so much im going to try this ,Wish me luck!!!

You can wash ,whit ,blaster brake cleaner.is more easily.

Nicely done, thanks you for that!

Hello friend. I love the video. I have an slk350 giving me a P0025 code. Can you shed some light on this? Is this only a cam position sensor? Or do I have to do the magnets as wel

Thank you for the video I have a better idea about the crank sensor thank you so much

Sir ; can you give me a idea on ? Labor time ?" To change 2006 MB C Class " Camshaft Magnets "4" Tyl , AWESOME VIDEO

Hello , nice troubleshooting. I have an 03 ML500 . Did the oil change and this time oil filter got pinched and oil leaked all over towards the passenger side soaking the front of the engine. Fixed the “o” ring problem , cleaned engine,, started it , all good . But a 15 minutes drive , parked it . Engine off . 10 minutes later engine won’t start. It cranks in lot more RPM. After half hour engine cooled bit more and first attempt it started drove home , towards the 15 minute drive got the check engine light. Put my scanner code 0340 I believe, reset check engine ran an hour rat idle truck did not stalled. Few minutes later ran another 15 minutes and it did shut engine with check engine light. Your thoughts on this issue . Everything else works on the car . Is this sound like a shorting something when the car get hot ? Your thoughts. Thanks

As always best videos on the net, you are a blessing, one question! I have code p0016 only, does that code tells me I have to balance the crankshaft chain? Forgive me if I didn’t elaborate on my question, I’m hopping I just need to replace those sensors, thanks again for sharing

What are some symptoms of the camshaft position going bad.... I have an R350

Wowww nice job. Thank you.

Good quality and quantity job Bro

Does the w211 have magnets on the driver side also? And would this along with bad plugs cause misfire and a jerky idle?

@iRepairAutos Thank you so much for this video. My 2004 c230 is leaking oil (109k miles). My mechanic says it looks like leak's coming from the camshaft magnet/sensor. He said the OEM parts alone cost about $500 each! I started to research this bc it sounded too much money for these 2 little round things! I found online these cost around $50-100/pc. Needless to say, I'm looking for 2nd/3rd opinions and info. If oil is actually leaking from these magnets (the 2 round parts), would there be accompanying parts requiring replacement that might make each one cost this much?? Also, is it possible only the seals (rings) need replacement --how could I find this out? By chance would you know of a good MB mechanic (not stealership) in the NYC area that charges reasonable labor rate? Much appreciated!

Thank you

Do you have a video on replacing the crankshaft position sensor on an 06 R350

Kind of upsetting that I’m looking for the actual crankshaft position sensor and your video clearly replaces the camshaft position sensor. Terminology dude, it’d help a lot.

Hi thanks for this video it is really useful. I have a clk280 m272 engine. The Solenoids are leaking, no related dtc's present. When I pulled the electrical plug from the solenoid it is covered in oil. Will replacing the o-rings be enough to prevent this or should I get 4 new solenoids?

Hi there, have been your subscriber for a while. That was the first video, I've seen on youtube while trying to resolve the rattle noise issue on my w211 (m273 - 2007 model). Can you pls answer my question: My car has slightly noticeable rattle noise for about 5 seconds once engine started. What I've noticed, that it happens once car left for sometime but mostly on cold engine. I do guess the problem might be with oil insufficiency in a drip pan and when I run the car after leaving it for sometime drip pan gets some kind of emptied, so first 5 seconds there's no oil coming to the engine. (have to mention that there's no oil leakage on the engine). However, its still my personal assumption...Could you pls guide me, what could be a possible reason of the problem? Thank you in advance.

Thank you, I hope i dont end up doing this but suspect I will. This leak happened on my 98 c280 so the 09 ML 350 is probably next. What year is yours?

Great Video! Need to ask a question as you seem to understand this well. I had the Check Engine light pop up on my 2006 SLK280 . A scan showed the P0015 code. It was the only code pulled up. Researching it, I found your video and saw what an easy job it was. Then, I notice the Check Engine light is now off after a few days of being on. My dilemma is should I take that as a defective sensor (for it to go on & off) and replace it anyway or am I OK and good to go? I just purchased the vehicle and had it checked prior to buying. Carfax was clean. The car only has 44K miles and the pre-purchase inspection came back good. I have less than 150 mi on it yet since I got it. Any recommendation? Thanks in advance!

great vid. are the o-rings available on amazon? cant locate them. any tips?

Which one is camshaft sensor A? Driver side? Or passenger side?

ive got p0012, p0022 and p0015 on my c230 2007. Will this solve the problem? I will change the oil before and see if the check engine still shows up.

Great video. Thank you

2011 ml350 I replaced all the position sensor + magnet still getting rough start when cold and p054b and p054d engine light is on

hello Keith, please what are the physical signs of this error code?

nice job!

Is it the same for a 2001 mercedes e320? I can’t find a video to help me replace my camshaft sensor

HI NIce video! I have a 2008 GL 450 code P343 "Camshaft position Sensor A Circuit High Bank 1 or Single Sensor" How do i narrrow it down to the sensor or the magnet? Would the magnet through a code? There is 2 on each side. Is there a way to test or just replace the whole side?

Codes P0014 & P0024: Solenoid and magnets; are they the same thing on an SLK R171 350? Cam' sensors have been replaced, oil change is next. Could the magnets/solenoids be the last step and should all 4 be replaced?

Hi Kieth I hope you can help me I have a Mercedes C390 2008 and I got fault codes P0024 and P0019 Is the cam shaft adjuster magnet the same as an oil control valve ? And also got fault codes P0304 P0305 and P0306 Would greatly appreciate it if you could help me Thanks

I have a 2013 E550 4M TT (W212) - dealer found oil on my camshaft position sensors (replaced) replaced camshaft magnets - dealer found oil in wiring harness and ECU - had to replace wiring harness and ECU - this is an expensive repair if you don’t catch it soon enough

Just the tip… 🤣 Do you always use Bosch or do you go with Dorman or someone like that?

i have a question i can see ur egr valve at the front side, i have a question that these egrs have three sides two on the upper side having vacuum pipes attached as also in ur case but what about the third on as in my car its open, is it the way it should be like or mine one is left open

Thanks for the video

Where is the variable valve timing solenoid? Is it where the magnet snaps in and if so can I take it out a replace it from that port?

Great video.

Really good video my man but, how would someone know to just replace the old rings or just replace the part?? I have an 2007 Mercedes C280 4matic w/ error code P0016 & P0017... I believe which are the camshaft sensors.

So what are the symptoms of those things going bad?

So the Mercedes have 4 camshaft position sensors? I have a 2006 ml350

Hi there Keith does this apply to gasoline Mercedes or does it apply to diesel also ,do diesels have same sensors on same locations on 2010 ml350 , I have oil leak in front part of engine dripping down Thx In advance

At around 12:06 what does it mean torqued down to 10? I'm a little new to this tools I'm going to need a torque wrench?

Thank you for your vid. Can you tell me, which side is bank 1 and 2? I have 2 check engine codes and I dont understand which one I must to change. P0341 - camshaft position sensor "A" Circuit Range/Perfomance (Bank 1 or single sensor) P2093 - A camshaft position actuator control circuit High bank 2 b)

Hi how many camshaft position in any bank three or two and thanks

Hi. I replaced the magnet with new OEM ones as a preventative maintenance and it is now leaking. It wasn’t leaking before. I took them out and inspected them and everything looks fine. The rings are the same and positioned correctly. Any clue what I could try now? I was thinking of buying a gasket making kit and using that to create a seal. Thanks

i have a 2006 mercedes c280 4matic. How do i locate the camshaft position sensor B?

Same 350 you replaced the oil cooler gasket on?? Do you have any input due to using synthetic oil and that is supposedly dries the rubber at a faster rate than conventional oil? Someone who works on BMW was talking abut using synthetic and how it dries the gaskets making them brittle thus leaking? Old school beam type torque wrench certainly much cheaper than click type

have a 07 mercedes e550 and while installing the sensors do u need to do any adjustments

I have a 2010 mercedes s600 with that problem of many others problem. Where would I find that on a s600?

What one is bank 1 and or bank 2? Got the bank 2 code but scared to guess which one!
