Clk 270 Cdi crankshaft position sensor

[davemc29]

Hi, can anyone advise me on how to change the crankshaft position sensor on my CLK 270 CDI on a 53 plate?
I have read that it can be done from above on some models but I cannot see how this is possible on my CLK and wondered if it can be accessed from underneath?

Hi

You need to do it from underneath in this model.
Remove rear under tray & reach up just above starter motor.

Thanks for the info Benza750. I will give it a go.

And if it's stuck in it can be a bit of a ****!
