Unhappy 2009 ML320 Bluetec CPS location

Can someone help on how to find the CPS location on my Bluetec ML320 2009. I remove the drive side filter housing and look underneath like half hour but didn't find it. I watched the youtube video for a similar car but I just can't find in the same location. probably because that's a right hand drive car and mine is left side drive.

anyone can help to find my CPS please. It starts right away when it's cold, but after short drive, re-stat sometimes need 3-5 times. Long travel on highway sometime stalls.

I assume you are asking about the Crankshaft Pos. Sen. which is referred to as the CKP.

Is the Check Eng. Light on because if there was a problem with the CKP, it will store codes.

But if you want to install a new CKP, here are the instructions.

Thanks a lot for the help. and apologize for the belated response. I did see the the CKP sensor from underneath the vehicle. it's covered by a metal shield that's why it's not visible from top.

Well I didn't get a chance to replace it, instead I had it traded in.

Again thanks very much for your kind help.
