Sorry if I'm really dense, but this link doesn't mention part # A2769051000 for my car (it shows only # A2769050900 for the camshaft position sensor). I also performed a search of the entire site for "A276905100" and got "Nothing found! Modify your search". Shouldn't I have at least gotten models with 8-cylinder engines when searching for that part number?
Please keep in mind the wiring is a dummy device to interface between existing female/male connectors using standard 2-pin/3-pin MB connectors. There is nothing special within them. You can disconnect the wiring from your sensors/solenoids to verify if they are 3 pin, or 2 pins.
You can also buy the connectors that match your current sensors, and buy automotive wiring and create them yoursefl. They are not rocket science, just the convenience to get them premade.
JCM_MB I really appreciate your patience and help with this, but there's still something that doesn't seem to make sense.
We've established that my car uses the following part numbers:
Camshaft Solenoid: # A2761560790
Camshaft Position Sensor: # A2769050900
The Amazon product listing indicates that the pigtails will fit camshaft solenoid part # A2761560790 (this matches my engine). However, the Amazon part # for the camshaft position sensor is A2769051000, which does not match part #A2769050900 on my engine.
On what are we basing the assumption that the Amazon product will fit the connectors on my #A2769050900 position sensors?

That is all about the PIN on the harnesses. If in doubt, you can always check continuity on both sides of the harness, and confirm they wire are not crossed (color visual check will do as well). They are just like an extension cord in your garage to connect your tools.
Check how many pins your connectors have, compare to the photo posted in Amazon (same above), and make your decision.
To be honest, even the guy (Dannny K) at FCP Euro got it wrong the first time around, and they were packaging 8 identical harnesses as a kit for the M278/M276, and they had to remove them from the webpage. See their updated video (

I watched this video a few months ago, but I just watched it again and he states that the pigtails will NOT connect to the Camshaft Position Sensors (he says regular replacement of the Camshaft Position Sensors is the only "fix"). Are you saying that this is incorrect, and the pigtails WILL connect to the Camshaft Position Sensors?

These are the pictures the shop sent me. They said the “timing covers” were leaking and would wick up the wiring harnesses on both sides. I can’t really see what they are talking about.
OK so I checked all four round covers (solenoid sensors, whatever they be) they are bone dry on top where the connectors hook up. However, I cannot for the life of me, get the connectors to come off. Yes, I clicked the little white locks in the up position, and tried with needle nose pliers, gently rocking back and forth but it’s like they are CEEMENTED on. If I try any harder I’m afraid I’ll break the brittle plastic. Am I doing something wrong? 😳 so how do I check if there’s oil in them without breaking the connectors?

The pigtails from FCP Euro will NOT connect to the Camshaft Position Sensors, ONLY to the Camshaft Solenoids. Why? the pigtails they sell are for 2-pin connectors while the Position Sensors require a 3 wire connection. That is what I told Danny long time ago (after another MBWorld forum member highlighted that on another post) before he re-recorded and corrected the video.
The advantage of the Amazon "product" is that it has the 2 sets: 4 3-Pin pigtails, and 4 2-Pin pigtails in one set. There used to be another seller in eBay back then offering a similar product.

Unfortunately, you are likely NOT doing anything wrong. It is extremely tricky to do, and to explain. Glad you are patient; otherwise, you know.
Let me see if I find you someone's explanation on video.

So as long as the connectors on my Camshaft Position Sensors have 3 pins, the Amazon product will fit?
I tried to remain patient and use very gentle pressure, and they did eventually come loose. I was very nervous the whole time and felt fortunate to have managed it without cracking any of them (I expect they often do crack). The prospect of doing this regularly is daunting.
Question, though. If the sensor covers and the connectors are bone dry, how would oil get into them?
The oil leaks through the sensors and flows along the actual wires that come out of them, and into the wiring harness. If you unplug the wiring harness from the connector on the sensor and the inside of the connector (where the pins are) is dry, then it's not leaking (yet).
Although the seller says they won't fit my car, an earlier post in this thread indicates that you have successfully installed them on a model with the same engine found in my car (my engine # is 276820 30 229332). Are you able to confirm that this set will connect to the following parts on my engine?
Camshaft Solenoid: # A2761560790
Camshaft Position Sensor: # A2769050900
Thanks!

thank you for that video JCM_MB! That might make all the difference. I’m going to try again later today and if dry, hopefully order and install the pigtails. But the pigtails would only delay the problem, not correct it, am I right?

The pigtails will not fix the problem, but they provide a warning and something of a barrier to slow down the oil migration before it actually gets into your wiring harness. If you unplug a pigtail from a cam magnet or sensor and you see oil inside it, then you replace the failed cam magnet or sensor along with that pigtail to stop the oil migration.

Thank you. So then all I need to know is, where can I get these pigtails? I saw a picture earlier but could not read which site it’s from or what the part numbers are. It’s for the 276820 30 172597 engine.
HELP! I got all four connectors off, drivers side all dry but passenger side both had a tiny bit of oil in them 😱 pictures below. Part numbers in the pics

So it would seem I need to replace both camshaft solenoids right? Would these be the best option (I believe it is a set of 2)?

If you have an E400 coupe, then I assume you have the same engine I do (some variation of the M276). What I've been trying to establish here is whether the pigtails in the Amazon listing noted earlier in this thread will actually fit the sensors on my engine. The seller on Amazon says no, but others here have suggested that they will.

If your part number matches the number in this product listing, then yes, this is the solenoid for your engine. I recommend googling that number, as you'll likely find the part on a variety of websites (including actual MB dealers sites), and probably with a variety of prices and shipping charges. Prices on MB parts can vary wildly from site to site.
