Doc, the past week or so I have been asking a lot of questions regarding why our 1999 E320 shuts off both when cold and after being driven at highway speeds. You ,along with others have led me to beleive the cps is the problem.I have also consulted our nearby German car repair service(who has done our repair work, and been very good at it so far) and they advised me to take it to a MB dealer. Shouldn't the computer recognize this new part and the two get in synch pretty quickly?? I wonder why they would have suggested going to a dealership.

factory service manual lists having the star diagnostic tool be used before turning the car over to the customer so you will have to go dealer

Have you changed the part? I would say that if it is stated that it is bad change it and drive it. see what happens.. No more stalling you win. it still stalls take it to dealer..

YOU can synchronize the crank sensor. Doesn't require factory scanner.

May require a scanner with live data info though.

Procedure goes this way, Drive car in 3rd gear...2100 rpm...30 seconds.. with a 50% load.

Keeping the 50% load is the hard part. Knowing you are at 50% load requires a scanner with live data.

Getting a 50% load requires just the right up-hill ride OR using the parking brakes.
Too much brake & they will burn-up.
