i have a 2011 E350 4Matic and want to replace Crank Position Sensor that i purchased at dealer.
All Thread says it easy but cannot seem to find where its located on the car and how to get to it.
Anyone know or have pics of location? i know its somewhere near firewall on drivers side but so hard to see and get to .
let me know thx

 

Just have a mechanic do it. It is a pain in the ***.

 

Ok understood but can you let me know steps that needs to be done .. I usually repair most things on my car and not opposed to trying. do I have to move any major parts for this? is there a diagram I can look at.. thanks

 

I replaced the CPS on my '04 W211 E500 and I don't think the W212 E350 is that much different. It is way back there and at an odd angle to get at the bolt holding it in. It is easy to drop the bolt on both removal and installation. Google search "Crank shaft position sensor on W211" on YouTube and you will find videos that may help with your W212. It is on the Driver's side bell housing. Be careful not to mess something else up in the process. Good luck!
