Well I replaced my CAM Position Sensor this past fall with one from Autozone (Made in China, $120) and I had similar problems as other members had posted in this thread, with the car not starting on the first try. I put the car away for hibernation soon after that but with a very early spring here I decided to order the Bosch part and not deal with any further frustration.

I was about to order it from this posted link, but at the last second I decided to do a google search and found it for a little cheaper:

Genuine Bosch Cam Position Sensor 0232103037 Mercedes | eBay

~$65 shipped, so I saved about $20 from the original link. Seller seems legit, great rating and claims to be an authorized Bosch distributor. I will post an update when I get it installed maybe this weekend.

I just wish I had seen this thread before I bought it locally the first time around
