DIY Replacement - Crankshaft Position Sensor (CPS)

• One BenzWorld Member stated; "Bought a Bosch, same as the Mercedes brand, for $45 and installed it myself. No adjustment needed after installation. Removed the old one, installed the new one and back in business."
• Excellent article by BenzWorld Member Gabby07621 on DIY replacing CPS.

Summary:

The plate is extended all the way up to the second torx screw. That is it was impossible for me to squeeze the connector out. I tried like hell and my right hand got several cuts from the efforts, but it is just not possible.

My way around it was to not actually remove the connector but just remove the E8 torx bolt blind and use the connector and line to fish the CPS out.

Awesomely enough, that was the perfect way to do it. All I had to do was line the 12" extender to the E8 bolt blindly and turn until the bolt was off and fish the CPS attached to the connector. It slid off with no resistance and putting it back on was exactly the same.
