Mercedes E63 W212 M157, 4 cam shaft sensors replace for sensors leaking oil which can damage ECU!

- very basic and a bit clumsy video i made about changing the 4 cam shaft sensors on a 2015 Mercedes E63S with M157 motor and 47,000 miles. This replacement of the cam sensors should be roughly the same for any M157 motor used in a Mercedes Vehicle.
NOTE - i commented that I had 1 leaking sensor, but actually 3 of 4 were leaking including both driver side sensors and 1 from the passenger side. Also had a very tiny drop of oil appear in a corner of my ECU. Everything was cleaned off with electrical cleaner spray and car has been running find and continues to drive perfect but it is critical to check these 4 sensors for any older M157 motor as the ECU and harness can get damaged if the oil from the 4 leaking sensors wicks up to the ECU.
Thanks for this. Today I have checked and replaced all four of the camshaft sensors on my 2015 CLS63S M157 using the FCP Euro kit at 45K miles. I had a small leak on sensor 2 and 3 looking left to right. I have not yet checked the ECU but I will. From what I can see on the forums Mercedes should have issued a recall for this issue. It may justify a class action.
Great video. I have a 2016 E400 6 cylinder and I installed cam positions extension harness to prevent any oil damage to ECU. When I was installing the cam position sensors extensions I carefully examen each connector and luckily they were bone dry no oil at all. Thanks to fellow UA-camr JoseRepair I found out how to prevent any oil damage and got my cam position sensor extension harness from ZZPerformance.
The cam magnets/pucks tend to leak as well. Check those out!
I thought mine was leaking too but it seems it’s a valve cover leak which is much much harder to replace
thanks for the video. mine was the oily same sensor next to oil fill
Dude thank you so much for putting this out there. You’ve genuinely helped me mentally prepare for owning my 2016 E63S. I wonder if these kinks were worked out in the 16’ models but idk. Maybe I’ll ask ChatGPT about it later. What year is your model?
mine is a 2015 E63 and am at 50k miles... definitely check the 4 cam sensors and cam magnets and ECU wiring harness for leaks on any car you're considering buying! Absolutely get a compression test done before you buy any M157 motor AMG as that plus leakdown & boroscope visual will help you avoid the "ticking time bomb" motors that have been abused, have valve issues, piston/ring issues and the compression test will help you determine that.
Exactly the same sensor on my e63 the rest was ok the cam magnetic also leaking
It helps fella thanks for the great content
2013 E350. I just replaced all 4 but the code is still there. There was oil residues on 2 out of 4.
I’ll replace the other 4 magnet adjusters next. My Indy shop wanted my arm & leg😢😢 to replace the wiring harness & other stuff related to code P0346 😢😢😢
Did it help the sputtering? (S63 M157 here) thanks to you I just looked and found all of them soaked with oil, ran to my laptop and ordered a set from FCP, thankfully nothing on the ECU connector, but I will spray it anyway once I got the kit, the reason I was researching this , my car sometimes sputter and has a long crank before it starts, and I'm talking once in while and not on cold start, it only happens after being driven then parked for about an hour or so it does that, then it's fine, and it's been driving me nuts, I'm hoping this will resolve the issue.
@gusf - i have had that sputtering/delayed start off and on with my car after about 35k miles. when i replaced the cam sensors / cam magnets and cleaned up the minor oil in my ecu wiring harness it was starting totally normal again BUT i notice that if I quickly turn the key to start the sputtering can return. now I put the key in ignition, turn it to position 2 (just before start) and wait like 1-2 seconds before starting and for some reason dont have any sputtering when starting that way.... i do get the sputtering if i just stick the key in and do full quick turn to start. still havent figured out why that happens (no codes shown, battery is good)
@@johnvakos9136 yea same here I replaced the cam sensors and honestly I don’t see a difference , I use the push buttons keyless but it’s the same Principle I press the with my foot off the brakes so it won’t crank right away wait for about 3-4 seconds and it starts normally , I think this a symptons of fuel regulator so I’m thinking of replacing the fuel filter next it’s one unit with the regulator in it , now here’s my exact symptoms , cold start no problem at all second start after stopping for an hour or so is where the problem most pronounced , and it’s also intermittent meaning sometimes it doesn’t happen at all, ohhh the mystery of Mercedes I love my my car but sometimes she drives me nuts😊😊
If you unplug the ecu and camshaft adjuster sensors, do you have to recalibrate the car after plugging them back in?
i didnt recalibrate anything... just removed the ECU and sprayed CRC electrical cleaner in the ECU and harness to remove the small oil residue and did similar on the camshaft magnet plugs before i put the new ones in. all good after that
Same here covered under extended warranty
Hey did you have to unhook your car batteries before unplugging your ecu?
i dont disconnect main battery BUT do make sure the car is off obviously. i usually pop the hood, then lock the car and let it sit for 5 minutes before taking the ECU out / swap with my other ECUs. not sure that is required
@@jvakos thanks for the tip homie! But do you disconnect the battery under the hood at least or nah?
How many miles on this vehicle
How come you didn’t replace Camshaft Aduster Magnets? I heard they leak too, but not as common.
i replaced the 2 cam magnets that are easily accessible and havent gotten around to doing the other 2 that are located behind the charge pipes. should absolutely replace them though good point
I ordered the new cam sensors and should get them from MB Parts Source. They are cheaper than FCP Euro. I didn’t see any oil in the cam magnets, but I will check every oil change. My GL has 54 k miles. It’s sad these engines have this issue this early.
Well....... just checked mine...... 3 of 4 have oil .... time to place another parts order
sorry to hear but not surprising. if you are in the US my suggestion is to buy the cam sensors from FCP Euro as they have a lifetime free warranty replacement and are nearly the same price as if buying from a dealer. i replaced my 4 cam sensors and 2 cam solenoid magnets from FCP and assume they will again leak and aside from my 1 hour of labor to do the work myself i will never have to pay for parts again with FCPs lifetime warranty.
I ordered the cam sensors last night from FCP 👍

Thanks! Mine are not leaking...yet... but I'll probably need them in the future.
Where did you get that intake setup?
www.blackboostusa.com/ very worth while mod... added 40HP per my dyno and dropped .3 off quarter from just this combined with my AMS 100 octane tune (quarter 10.42 and 133 trap)
Are all 4 sensors the same part number?
yes same part number for all 4 cam sensors www.fcpeuro.com/products/mercedes-engine-camshaft-position-sensor-mer-2761530028
@@jvakos thank you
I’m getting code p0347
promosm 😓
