I have replaced mine. Taking the passenger side cat out makes it easier to get the bottom bolt. I used a flex 1/4" ratchet to access the bolts from the top from the engine bay. You can remove and replace from the bottom.
Current concensus is that it's not a 'fix', as even the newest sensors have started leaking again down the road, but the wire extensions have a much higher potential to save the main harness if you are checking them at oil change intervals.
Previously I thought we only had pigtails for the cam magnets on the front face of the motor, but someone posted yesterday in the other thread FCP carries the harness for the CPS sensors too. So 8 pigtails in total.
The PCV repair in this thread is interesting and makes a lot of sense, however if the original fails like this it's bound to happen again, just like the sensors, so no matter what the wire harnesses still need to be watched at somewhat frequent intervals.

Where are you seeing that the confirmed latest part numbers for sensors and magnets are leaking?

Happened to my own GL63 after about 20k miles, replaced again under warranty along w/ harness, ecu to the tune of about $18k. When it happened again I did some thread searching and found one or two others seeing sensors leak again. I had the dealer confirm part numbers on the failed units and they were the most updated ones. Given it wasn't all of them, but two were definite smoking guns, both CPS sensors I believe, only trace at one or two magnets.

That seems correct.
My 2006/7 C180K has only been fitted with two pigtails - and a new wiring harness - and new cam gears and chains!
Perhaps different models have different leak points.
It is currently running very well - after 4.5 months off road.
Have tried many avenues to redress this failure by M-Bz to warn Australian owners back in 2012.
Due to time passed the consumer agencies would require me to get a finding from a lower legal entity, class action firms are hot on the diesel emissions class action but want at least seven Australian owners who suffered losses to contact them.
I am willing to broker such contacts - appears it is affecting models up to 2017.
It is easy to see the oil in the clip-on coupling - mine was brimming with oil.
so these sacrificial dealies ONLY fit the magnets ... not the cps... does anyone have the part number for the cps? I'm not too worried since I can replace the cps but can't easily replace the magnets
1991 964 Turbo, 2002 Black E55, 2002 Black E55 " The Beast"- 2014 E63s
Wagon going in tomorrow for a yearly check-up. One of the few things on the list is to check the CPS sensors, the wiring harness and servicing the pano.

I've been all over FCP and can't find just the pigtails for the cam position sensors. Note: The magnet/solenoids have 2 leads and the CPS have 3 leads. They DO offer this kit which includes the pigtails AND the sensors, for $192.00.
I will contact them and see if they will sell the pigtails only.
!!!!!!! I just cross-referenced the part #s referenced in this kit and the pigtails listed are the 2 lead pigtails for the magnet/solenoids!! I will try to discuss this with them, Sigh

I already contacted them. That kit does not have pigtails that work for the camshaft sensors. It's the same harness thats posted above and only works for the magnets

Yearly check-up resulted in replacing the coolant reservoir and all 4 CPU sensors. SA mentioned couple of them showed slight seepage and said could wait for now but I had them go ahead and replace all 4, good for now. ECU harness was not at risk though

Im going to need a refund now, I’ll send out an email
Take photo of your CPS connector.
If it is the same as M276 3.0 TT, you can make your own kit
This is my CPS
Lets call above as MALE connector.
Assuming your engine uses the same connector as mine, you can buy the MALE and FEMALE set
I bought the above for testing/troubleshooting purpose, not oil seepage protection.
===================
My M276 3.0 TT phasor magnet connector. Finding the female for this MALE connector below I have not been succesful. This connector brand I believe is KOSTAL, not Hirschmann.
LK logo is usually KOSTAL.
==================
Any male connector on our engine, we can buy them from MB.
However, the female is always at the device/sensor, sometimes your may be able to find stand alone female connector, but not always we can find it.
Most connector manufacturer will name connector's gender opposite to what I call them, because they describe the copper terminal and not the plastic body.
This is called FEMALE by manufacturer, see the terminal. I call it MALE
This is called MALE by connector manufacturer
When assembled
====================
What you guys can do to make a sacrificial connector kit, worse come to worse ( and not looking too pretty ) is to use other brand.
Example a good and easy one to use is Deustch connector https://www.buydeutsch.com/collectio...sch-connectors
Device or sensor>>MB MALE connector>>>>cut wire harness in the middle>>>use Deutsch connectors>>>>original harness
MB has special deals with Hirschmann and Kostal for certain connectors and sold only to MB.
Usually it is the position of the groove called KEY Type which is different on MB cars, compared those sold in open market.

How you can maximize prevention of oil seepage to main wiring harness is to allow oil to leak out at the DT connector as OIL LEAK SIGNAL.
Simply remove the seal for the wires at the side of the connector where it is facing the CPS/Phasor magnet
The insertion depth of the wire & that male round terminal is deep enough. as such when and if the orange silicone water-tight seal is not installed, the bare male terminal wont touch any metal parts of engine.
When you buy any MB connector from MB, you only get the plastic connector body, item 1. The female tinned copper terminals item 2 and each individual wire seal item 3 is not included.
Anyone happen to have the part number for the oil level sensor connectors that were mentioned earlier on in this thread, do you? If I am going to make my own pig tail harnesses I might as well make one for that as well. Thank you for posting all of this up. Installing new sensors with these jumper harnesses should reduce some of my anxiety about this car.
