How to change camshaft adjuster magnets and position sensors on a Mercedes Benz - W222 |  

Thank you for making this video for all of us. My wife's 2015 S550 just started acting up. We purchased it off lease at a small dealer in Santa Monica, CA, and I usually do the oil changes and brakes, but recently it had coils go out. First #7, then #8. With 67k miles, I figured it was time for plugs. I only broke one stubborn coil (#3), but moved #1 to #3 so when it arrived the next day it would be easy to install. I do notice some weeping of oil around the magnets - not the sensors, and have ordered the sacrificial harnesses. I have also found and ordered O-rings for the magnets, and an inch-pound torque wrench - since I have a 1/2" drive ft/lb wrench only. So... I'm only planning to change the cam magnets, and then I will clean up the front head cam covers with brake-clean and keep an eye on everything. It's possible the cam covers are weeping oil too, and I have found and ordered a small tube of the grey Permatex silicone liquid gasket for about $8. The only thing I do not have are the 12 replacement bolts for the magnets. Do you know what the part number is for those bolts? That was a long explanation, but my reason is that taking the 4 metal intake tubes off is just beyond what I've done on this car. I need all the moral support that I can get to do this. I just know those tubes are going to be stuck like glue on the bottom side, but I watched you to the end and I promise I will grab each tube and wiggle, pull, wiggle, wobble, pull some more, get coffee, and repeat until they come loose! Oh my gosh, what have I gotten myself into now?

Awesome Jose !!! 😃😃😃

Jose, great video instructions, I just purchased my first Mercedes 2012 S550 and installed the sacrificial harnesses per your recommendation. I also purchased the 4 orings for the magnet sensors but I was not sure if the orings prevent oil from going into the harness or just to the outside engine block. When I disconnected the existing harnesses, I did notice a bit of oil on 2 of the connectors. I have not replaced the orings yet, but now I have seen your video I will do so. I would greatly appreciate your feedback.

Wow you are great

Finally got to adding sacrificial wiring harness today everything looked dry ... i changed to cam shaft sensors a couple monts ago because i spotted oil... 2014 E550 caborlet with about 32,000 miles on it , Love the car hoping to have it for a long while

Your video is saving us a lot. Thank you! I’ve 2013 E350. Does Magnet and position sensors are same part for E350 v6? Thanks!

Awesome! Looks simple enough. I am waiting for my parts from fcp and will have this done soon as well. So i need 10 new bolts from the dealer? Do you have part numbers for the bolts? This video will help many, thanks!

Amazing. Thank you. I have a wonderful 14 e550a. 70kmiles. Dealer just inspected. No oil so far. What is the risk of using the sacrificial harness as a oil path block? Does it affect the electronic or electrical performance of the circuit? Or extended warranty? What about intermittent poor connectors?

Also sorry do you need to unplug the battery in order to change them ? And update it into computer all those parts which we installed? Thanks 🙏

that wife is a keeper! 😁😁 btw how much in parts to do this job??

The parts you changed help eliminate engine noise?

Forgive me for stupid question but why do you need new bolts? Can’t one add blue lock-tight to original bolts instead?

Hi at what mileage do you need to change them ? And how many miles already you car has ? Thanks

How many miles did you have when you did this service? What led to you needed to change those parts? Did you have any issues?

It's not as bad as I thought it was. The people at the dealer are ridiculous with their prices

Which is sensor B Bank 1 that’s the code I got

torque specs?

Why did you install pig tails on magnets. I taught cam shaft sensors only leak not magnets?

I’m getting code p0347 bank 2 sensor A

i have p 0016 V8 MERCEDES
