To answer a number of Qs, here here go!

1) It did fix the problem. No stalls since changing out CPS.

2) I should have noted, though it is stating the obvious, is that I would only do this on a COLD engine.

3) No resetting of anything required (as far as I know), as the engine was off and its not a vehicle/VIN specific part in terms of absolutes, just a range of VINs (and maybe 320/430/500 specific). The dealer wanted the VIN to make sure he gave me the correct one. I am not sure how many variations there may be, I did not ask.

4) It is on the back, drivers side of engine, where the engine/transmission mate up. Its kinda a PITA to get at. I purchased the part before I started so I knew what I was looking for. The external torx socket is difficult to see, but you can do it. Good lighting is essential or I don't know how you would find it.

Best wishes on your ML travels and DIYs.

PS-This vehicle, so far, is not as difficult to work on as my BMWs. Try replacing a cabin filter on a e36 BMW. Now that is a frustrating job in comparison to the ML cabin filter.
