Mercedes has been using the same solenoid and position sensors on their camshafts for many years. So, if you bought solenoids or sensors 10 years ago, they still fit your newer Mercedes.

This harness is for the Camshaft Position Sensors actually! They are the ones that leak oil from the engine through the sensors to the plug and harness. The camshaft Adjusters do not leak oil so far so you need to change where you are installing the harness. Just trying to help you guys so you don't get confused. I have a video on my channel about the leaking camshaft position sensors in my channel. Please view it to understand... Thanks and Good Luck...
Thank you so much for your comment. I have another video on the position sensors as well. They are different harnesses. The harnesses on this video do not fit on the position sensors. If you want you can get both and see the difference. I will definitely see your video.
Yeah....I'm under the hood and discovering these harnesses don't fit
Is there way to find out if it's already too late to change those? I am getting a facelift CL500, but not sure if that's been changed or it has already leaked oil through the harness or not. Car has 170k
You will be able to visually see oil on and/or inside of the connectors if it's leaking. Just unplug them and take a look.
On a Benz with that many miles, you will definitely be able to see oil if the extenders have not been installed.
awesome video, just ordered the kit from fcpeuro for my s550 thanks to you . I also got a serpentine belt and plan to get the pulleys as well. A how to video for pulleys and belt would be awesome. keep the videos coming!
Thank you so much I’ll work on it
Mercedes Benz needs to come up with pigtails made of anti-capillary wires so it stops the oil, from my understanding, these pigtails don't do that, I believe they only intercept the oil and you still have to change the pigtail before it gets all the way through to the harness plug on the other end of the pigtail. My 2013 S550 had this issue a few months before the dealer sold me the car. The cars original owner took it in and the repair was $16,000. They pulled the engine and replaced the harness, the ECU, injectors, 02 sensors and a few other parts the oil got to. The dealer who did the work told me it will happen again even with the pigtails. It happened at 60,000 miles.
Thank you for your comment. Hopefully they do come up with something. Meanwhile we have to keep an eye on the solenoids and position sensors, and if they start leaking then yeah, throw out the pigtails and get new ones when you change the solenoids or sensors. One of my subscribers told me he had this issue at 30,000 miles. So we have to always look out for leaks.
I’d suggest they didn’t need to do all that.
A poor dealer will just replace the lot to prevent a return.
A good dealer will inspect and replace as necessary.
@@gottliebdee263 unfortunately there’s no permanent fix for this issue on the M278 engine and Germany has assured me they’re not going to do anything. The fix is replace the entire wiring harness of the engine and anything else the oil ruins. There is however a company on eBay that made pig tails for the cam sensors since Mercedes never did, but the pigtails are only a bandaid as it will continue to happen. Dealer just does what they’re told.
@@MercedesMechanic you are correct. We have to keep an eye on the solenoids and position sensors.
I just installed the pigtails, 1 of my 4 sensors had some oil on the factory plug.
Don’t need to do anything besides replace the solenoids. Will putting in the sacrificial pigtails stop the oil from advancing. Don’t need to worry about the oil that already touched the harness?? I believe it just started as there didn’t appear to be much oil. Other 3 solenoids were clean. I also have zero issue with my car. It has 81k miles on it.
Just need to know if no need to do anything else besides replace solenoids and add pigtails with the presence of a little oil?
That known problem was the reason I didn’t buy that car. Didn’t know they made a kit for it. Great 👍 video
Thank you so much for your comment. Now you have a reason to get it. It’s a great car. What did you get instead?
I got the 2003 CL55 amg its me ricky@@josecitomarin
Just watched a similar video by FCP Euro and the tech said the ‘pigtail’ protects for the life of the car.
Thank you so much for your comment. I certainly hope so.
Great video on the sacrificial harness for the camshaft adjuster magnets
Glad you enjoyed it
Great video. Wondering if I should look into this for my 2016 E400.
Thank you so much for your comment. Is definitely worth looking into it. Look at the part number in your solenoids and see if they are the same. They may be, because even the C300 uses the same. The problem really is with 8 cylinder engines.
@@josecitomarin I just ordered 4 each cam solenoid harness extensions from Fcpeuro. Thanks for your video.
I though that only older Mercedes like W211, W204 and W220 have this type of problem. 🤔🤔🤔. Your transmission oil & filter will be changed at every 60,000km together outlet adaptor to avoid oil from going into TCM?
Thank you so much for your comment. Mercedes Benz has had this issue for many years. There are some modern cars that are being sold back to Mercedes with a damaged harness, by costumers that did not know the issue and did not want to spend the money fixing it. There are also some lucky ones that even got the issue while still under warranty and had it all covered.
A "pigtail" is a cable with a connector only on one end and loose wires on the other end.
Thank you so much for your comment. I keep learning new things every day.
That you for the heads up!
No problem. I am glad my video is helping
This issues even extends to the s550 from 2007
Thank you so much for sharing
Thank you changed cam shaft sensors but still getting oil will use this pigtails have 14 e55o with 32,000
Thank you for your message. Have you checked the solenoids for leaks? Those pig tails are for the solenoids.
@@josecitomarin will check , order 4 and will install for prevention , question do you think oil is coming from camshaft adjuster magnet
Those are the solenoids. It could be. If they are leaking they should be replaced. The pig tails will help so you harness doesn’t get damaged, but if they are in fact leaking they should be replaced. Just make sure they are leaking. It looks like you don’t drive your car to much. There is not enough lubrication on the seals
@@josecitomarin Thank You again , I will change them when the weather warms up here in the Northeast, it doesn't look to hard to do , I fig I would put pigtails on now to protect ECU , the 2 on the right by oil fill were both leaking other side was dry, Thank You again all input is appreciated
I’m in Jersey looks seems like we are close. Maybe we can meet and see what is going on with the car. If you saw my other videos you know I got an S550 as well
Thanks for the info
Thank you so much for your comment. No problem
I think these pig tail harnesses have their strands of copper wires that sealed off or are soldered solid to prevent it's capillary action that stop the leaked oil from travelling into ECU. But not sure about the one on camshaft or crankcase position sensor. Any pigtails for these.
Only last year my mechanic had fitted my infamous M271 engine with pigtails. At that point had yet to notice any oil sticking on any of its multi pins.
I had been thinking if premature wear on sprockets, timing chain and the holes of cam magnets (as seen in U tube) could be somehow be aggregated by flustered ECU making small but erratic adjustments leading to failure well before it's intended 250,000km lifespan. 🤔🤔🤔
I will forward your link to anyone I know that has a Mercedes. Thanks
I think, on a yearly PM basis, I must disconnect the large ECU adaptor & spray in some electrical contact cleaner & swipe it clean with an oil absorption pad. Next year I will replace the adapter connection located on the automatic transmission body.
Regards.
You have very good points. Thank you so much for your comment. If you see part two of this video you’ll see the pigtails for the position sensors. Please send the link.
@@josecitomarin my option is to change to new position sensor for camshaft &/or crankshaft as I think these are coming to 17 years on the car. Not sure if they have ever been replaced. If they had been replaced says 5 to 7 years back then putting in pig tails is a good option. 🤔🤔🤔
@@whlawson5812 even after replacing the sensors and solenoids it’s a good idea to add the pigtails. I changed all 4 sensors and all 4 solenoids and added the pigtails. Extra security. Only one of the solenoids was leaking, but I changed it all
@@josecitomarin I think after replacing old position sensor with I will cut up them to have a look. I am reasoning that the camshaft adjustors does have pressurized oil to allow it's modulation to take place - this would be the source of oil, gradually over time, leaking of these adjustors.
But tips of the camshaft & crankshaft position sensor are not exposed to pressurized oil of say 0.5 to 2barg. Yes, no?
After cutting up & have a look on these old sensors I will still have time to decide installing pigtails for them. 🤔🤔.
Regards
@@whlawson5812 you could be right, but you could also be wrong. I know the pigtails won’t hurt the car in anyway. They are just extension wires. So when I saw the price I didn’t think twice
This is the same on the V6 Ml 350 2014 model I have one now same issue
Thank you so much for your comment. Yeah the same sensors are used in many models
How do I know if the oil has reached my ECU? Would i check the ECU connector for oil? Car is misfiring in cylinder 2 and 4 and im getting camshaft sensor codes with a short circuit so I’m pretty sure I’m having this wiring harness issue.
Thank you so much for your comment. If it got to the ecu you would have a lot of problems and lights. So it looks like it didn’t reach that point yet. So change all of the cam sensors and positions sensors and install the pig tails. Make sure you clean the connectors really good. Also check what your spark plugs 2 and 4 look like
How do you know when this sacrificial harness is damaged?
You still have to keep an eye on leaks and oil levels. So you will see them wet. But they will keep most of the oil before it’s too late. When you see that the sacrificial harnesses are wet replace them.
Fcp euro does not sell camshaft harness, they only sell the cam magnet harness
Correct. It’s the sacrificial harness for the cam magnets or cam solenoids
@@josecitomarin eBay seller Zzperformance sells a kit for both cam sensors and cam magnets for our cars. Might want to add that to your comments of video.
Awesome. Thank you so much Joe. I got the harness kit for the position sensors thanks to you. I did a video on that. Please take a look
@@josecitomarinyou are very welcome!! Glad you were able to find them 🤝
Great. I’m glad you are doing it
Hello i just would like to ask I bought c63s it drives normal no abnormal engine sounds maybe a little sluggish in comfort mode i only got two codes p002177 and p001177 the mechanic told me the cam adjuster are ok and he’s going to check and probably going to change alot of stuff and it sounds expensive what do you think car with 80km 2017
Hi. I would try changing the position sensors and solenoids before anything else. Just follow my videos and do it your self. Make sure you add the pigtails while you are at it
Thank you!
No problem
It’s happening to 2021 E300 4 matic too ?
Thank you so much for your comment. It’s happening even to smaller 4cylinder engines like in the C300. I would play it safe and put it on. It won’t hurt to install it. It’s just a small extension of wires.
What the parts numbers ? I’m trying getting from MB dealership they said i don’t need one .
@@rudyvancolfort7072 I have the links on the description
Good diy video thanks so much, I just ordered mine.
Great I’m glad it’s helping you. Make sure you see part 2
@@josecitomarin will do thanks.
Thanks for sharing.
No problem
Hi Jose, does those harness will fit Mercedes G63 2014 with engine M157?
Thank you so much for your comment. Yes they do.
@@josecitomarin Many thanks for your quick response , I’ve ordered them yesterday from the link you provided under the video (zzperformance)👍
@@v0ss3n No problem. The other wires you have to order are from the dealer. One set is for the position sensors and the other is for the camshaft solenoids
@@josecitomarin yea, I’ve watched the other video, ordered from FCPEuro in USA, should receive them this Friday to Switzerland 👍
Maybe you can advise me, if I need to disconnect the wire like this guy did on his E63 ?

Hey Jose, I bought a 2014 s550 with 120k miles, just got it back from the mechanic. they said it will start making a knocking sound eventually and will cost 10k dollars to fix, said it has internal issues.
can they tell that all of that is going to happen just by hooking up their tester? ty
Thank you so much for your comment. One damage I know that costs 10k is the main harness replacement. That is if they found oil on the computer side.
If they hear a knocking maybe they found something pulling out a spark plug. The tester won’t tell you what is going to happen. It will read codes if the car has any. It’s a good idea to have a tester at home. Do you feel anything while driving?
@@josecitomarin Hi thanks for responding, no problems during driving. the car drives perfect.thats why I couldnt understand how they know the engine is going to go bad
@@Miamiflow885 no problem. Definitely ask them why they said that. Check your wiring. Why did you bring it to the mechanic in the first place?
@@josecitomarin radiator hose had a leak, 690 dollars to fix it
@@Miamiflow885 wow. A lot of money for a hose. See if they’ll tell you what they found. If not you are going to have to check your wires and take a spark plug out and see what you find in there.
Can I use this if the camshaft sensor already started to leak?
Thank you so much for your comment. You should replace the sensor and then install the pig tail. The harness only slows down the issue. It doesn’t stop it completely. So make sure you replace your position sensors and solenoids
@@josecitomarinthank you
@@DJRip83 no problem
So we need two order two sensors right ? One for each side ?
Thank you so much for your comment. There are 2 sensors on each side. So you have to get 4
Does this apply to w212 E350 or it’s just for v8?
Hi. They use the same cams for many of their models even the C class. The E class is included. Checkout the description of the video for the full list
@@josecitomarinthanks!
@@santagautam115 no problem
How do know when they are damaged and to change them again?
Thank you so much for your comment. If you see them wet again. Specially if it’s on both sides. They give you sometime for you to replace the position sensors or the solenoids. So if they are wet, you have to replace the position sensors and solenoids that are leaking as well.
Thanks for responding. Do you mean the sacrifice harness will get wet? Then you just put new sacrifice harness again? Thanks in advance. Keep the great videos coming.
Right. But if they got wet is because the sensors are bad. So keep an eye on them
hey Jose are this suitable for mb cl500 2008 s class 500 coupe
Hey. I don’t think that era was affected by it. But it might be worth exploring it. Look for the part number on your solenoids and see if it’s the same as in my list of parts. If they are, I would get the pigtails just in case.
If i already have an oil leak in the engine harness will these work or is it too late?
Thank you so much for your comment. Hopefully it is not too late. Just clean the connections really good and clean that leak. Then install new solenoids and position sensors if you have to, then sacrificial harnesses as soon as possible. Make sure you do all 4 solenoids and/or all 4 position sensors. No sense on doing just 1 or two. They other are going to leak eventually. Here are the links. Also make sure you see the other videos

Crud, Kevin at FCP EURO says there are no such csbles for my 2019 C300 inline 4. Can that be correct? I find it hard to believe
Hi. Thank you so much for your comment. Mercedes uses the same adjuster magnets in many cars. If you look at fitment under the part number in their website you’ll see that the same harness fits your car. The part number is 2711500156. Not many of the C class have this issue, but it doesn’t hurt to be safe and put them on. I would just order them and see if they fit. They are only $10 and you need 2.
@josecitomarin and thank you very much for your video. I completely enjoyed it, such a beautiful machine 👍. I just ordered the harness, thank you again for showing us this!
@@shireoryx6153 you are welcome. Make sure you see the other videos and stay tuned for the ones coming.
Jose, i just went to install the sacrificial harness i bought from fcp and unplugged the sensors and noticed a little oil on end of the plug, so i then took the whole sensor out and noticed they had some oil in them as well. are the sensors supposed to have oil on them but not the plugs or is nothing supposes to have oil?
You are not supposed to have any oil on the wire. Don’t run the car until you replace them. Replace cam magnets and cam position sensors. You can get them at FCP as well. I am working in the video on how to replace them. So order them and wait for me to release the video
@@josecitomarin but is it ok for the sensor inside to have oil on it? the plugged in side.
@@Rmayrap no it’s not okay. That is why you have to replace them. The leak into the valve and that is how the oil gets to the main harness. So don’t run the engine until you replace them. Hopefully it’s not too late
@@josecitomarin but how does the oil get in? The wires are not oily. Just the inside of the sensor and the inside of the plugs. Where does the oil come from?
@@Rmayrap it’s engine oil and that is the problem the sensors have. They leak into the sensor and then to the harness. That is why they created the sacrificial harness. One of my subscribers also found somebody else in eBay that sales the harness for the position sensors. I’m going to be getting them and install them as well. I’m glad there is no oil on the wires. Clean the plugs really good with electronic spray.
add m271 same problem
Thank you so much. Will do

What solution to remove p0016 🤣🤣🤣🫣
I think you should start by checking your wiring to camshaft position sensors and solenoids. Than I would go by changing the cam position sensors and solenoids.
I change all capteur just capteur solenoide i never change
@@roro85600 try that and make sure all the wiring is correct. Also check that there is no oil on your connections
