crankshaft position sensor
The crank sensor of my 2004 CLK320 is located in the back of the engine. He kneeled on top of the engine and dipped his hand inside the back of the engine, right in front of the windshield.
Now you know exactly where this item is fitted, do you think that it would be easier to get at from below? With the plastic covers off, of course. I don't like the idea of kneeling on the engine...
-remove your airbox
-look on the drivers side, behind the valve cover there is a 1 black wire at the bottom just above the tranny, its kinda cramp in that area, so a mirror is handy...grab it and trace it to the back of the motor...you wil need a socket, a 6" extention and a 1/4 ratchet, i forgot what size the torx socket size is...
-To make the DIY easier, i temp-disconnect the fuel line, and removed the driverside valve cover so i can access the plug. Its deep in there so its gonna need lots of patients and small hands.
- If you remove the fuel line and the valve cover, this DIY should take you about 1/2 hr.....if you do not remove the items, it will take you a few hrs plus shredded arms..haha
you cannot get to it from the bottom or the wheel well...

i need to replace this and get to work on tomorrow

thanks in advance
Your C320 uses the same M112 engine, right? Try this diy, which covers the topic very well.
