2x - 271-150-27-33 - Isolating wire
2x - 271-051-01-77 - Cam sensor

So...where is the isolation wire goes?

Just so you all know, the cam magnets ARE NOT the cam sensors, the Cam sensors are located on each side of the cylinder head, close to the front of the engine...
Part number 271-051-01-77 is a cam magnet/cam actuator, NOT a sensor, just found out...

That is possibly the seal on the transmission connector. It has probably leaked enough to be low on fluid, and perhaps destroyed the TCU. This is the wrong thread to post in unless you pulled the cam sensor connectors and found oil there.

I just did this work as I found a little drop of oil in each of the cam magnet connectors on my 2005 C230K with 70K miles on it. You'll need to remove the little cover on the front of the engine. No tools needed, just pop it loose from the rubber bushings. After that, a small external torx socket is required. As mentioned, you'll need:

2x - 271 051 00 32 - Expansion Plugs (called "cover" on mine)
2x - 010 997 23 48 - Seal Rings (just an o-ring)
2x - 271-150-27-33 - Isolating wire (called "starter line" on mine)
2x - 271-051-01-77 - Cam magnet sensor (just called "magnet" on mine)
2x - nylon zip ties (also called tie-wraps) get them anywhere

Also mentioned was autopartspeople.com which I found to have pretty decent prices on factory parts. The first part, the expansion plug (called "cover" on my part bag label) is the rubber plug that goes in the center of the magnet. I installed the new magnets without first putting the new plugs in. Don't do that! It's a little more difficult since you might drop the plugs down into the void. The new plugs did not look like the old plug used on the original part, which confused me for a second. The seal ring is simply the o-ring that goes between the magnet and front of the head. The isolating wire is a short piece of harness that has a male connector on one end and female on the other. Put it between the magnet and existing harness connector to stop future oil from migrating down the wires. You'll need a "zip tie" or "tie-wrap" to secure the new bigger bunch of wire/connector to the two brackets that support the little cover for the front of the engine. To save yourself some money, you might consider leaving the magnets alone, since the new isolating wire will keep oil from damaging the other stuff. You may get a worsening oil leak but you can replace the magnets then. Easy job, less than an hour, have fun! (...and thanks to the previous posters for all your help. made my job so easy)

I'm about to do this myself but is this totally covered under extended warranty or is it just a matter of if they want to cover it or not? Will the dealer accept 3rd party extended warranty?
