How do I replace the camshaft position sensor. Does anyone have a link to video or instructions?

Just did my wife's Ml500 which was a tough job. I have heard the V6 is easier than the V8.. I tried to go through the drivers side wheel wheel but couldn't get the heat shields out of the way enough to get in there so went from the top. Not sure I would do it again not knowing anything. Now that I have done it, it's easier.. I spent at least 2 hours trying to figure out how to get to it.
I would second everything said here.. I did it and started wishing I had not started an hour into it. I have scratches up and down my arm and wasn't smart enough to put a blanket down till I almost passed out. I had a HUGE fear of dropping that screw into the engine or loosing it. I ended up taping the screw to the socket with electrical tape putting it back in. 7 out of 10 is generous. You cannot see anything and there is a heat shields around it. 1/4 extension is all that will fit. Good news is that the sensor on Amazon was $36 (Bosh) and the exact unit, part number and all that the dealership sells for $200. Now that I have done it, I could do it in an hour. My first time took me over 4 hours and a ton of second guessing what I had attempted. If you can afford it, have the dealership do it. It you can't, prepare for a tough job.

I have heard that the V6 is easier than the V8.. I have also heard you can do it from the drivers wheel well when you remove the liner and heat shield.. I tried and was not possible for me...
