M157 camshaft sensors

[clk320x4]

Salutations everyone!
I have a question regarding the cam sensors for my E63 M157. MB sells them for about £65 each, but you can get Febi ones for roughly £15. Is there any difference in quality or anything else? I am grateful.

Good day!

You can't go wrong with genuine Febi goods. Keep an eye out for fakes sold on eBay.


I just changed all four camshaft sensors on my m157 since I found out one of them was leaking oil. After doing some additional research, I discovered that they were more fairly priced on Autodoc, therefore I ended up buying mine from the MB dealership instead.

Continental is the brand of tires that appears on the MB OEM sensors.

Some bunches from 63motorsport are a good investment, in my opinion. It will aid in preventing oil from possibly making its way up the wiring loom and into the ecu.

You are aware that heatshrink can be applied with a heat gun. 😉

What kind of protection does the addition of pig tails provide against oil seepage up the wiring looms?

Beneath that heatshrink is effectively a Raychem solder junction. The wicking process is halted when a solder block is placed on the strands. The early M271 engine, which had issues with the camshaft adjuster magnets, was the reason Mercedes made these. Interestingly, the issue didn't arise until Mercedes abandoned the long-used configuration of their wiring plugs. Modern techniques involve crimping tiny pins to the copper strands instead of soldering them, as opposed to the previous method of using large, spherical pins. Unchecked, the oil will wick up the copper to the other end, which is shocking to some.

Both the magnets and the kits for the camshaft position sensors are available at 63motorsport. It serves as a protective barrier against oil ingress and the capillary effect of oil travelling up the car wiring harness to the ecu. It would seem that the position sensors of the camshaft are more prone to failure.

Here we have the Mercedes-Benz variant of the M271 component. Back in the day, there was a service drive to get these fitted.
