Reading through the posts, I've seen mention a calibration that needs to take place once the crank position sensor has been replaced. Is this needed and how is it done?
honestly, i just replaced mine and started the car. no codes or anything. not sure if i "got lucky" or something but I definitely did not calibrate anything.
The first I've heard of indexing the stock CPS on newer MB engines was ohlord's blithe reference to it in another thread...and his silence on the topic thereafter.

Yea - before I dive in, just wanted to check. It sounds like many folks have done the replacement and there have been no comments on additional steps. The labor time in Alldatadiy shows labor at .8 hours - not enough time I would think to do much more than replace the sensor.

I didn't do calibration on 2 CPS I replaced on 2 different cars. They run just fine.
The .8 hours doesb't cover fishing for dropped screw and drinking beer.
The relevant WIS procedure is AR15.12-P-2133A, Remove/install crankshaft position sensor.

If the crankshaft position sensor was replaced, a re-initialization must be carried out with STAR DIAGNOSIS in the menu item control module adaptations.
Replaced mine myself and didn't have this done and don't think I have any problems. It sure fixed the problems I was having.

No SDS indexing is needed,the proper procedure is directly after replacement.
Start the engine and slowly bring the rpms up over a period of 2 minutes from idle to 2500 rpms,this allows the new cps to index itself to the ECU and really set it into sync with the flywheel indexers.Do it and the car will run better,don't do it and you may never know what you are missing
I haven't eaten any hats yet,nor do I run around with 10 year old brake fluid.However,It would be wise when the member that makes a habit of non maintenance of his and his family's vehicles learn something about anything before he opens his hat filled mouth and other orifices
