►While Mercedes has used a host of different engine blueprints from the early 2010s through 2023, many parts within the injection and timing system have remained consistent. From the M276 to the M278, M270 and M274 to M260 and M264, the M157 and M177, and even the M256, M133, and M139, Mercedes used the very same Camshaft Adjuster Magnets and Camshaft Position Sensor architecture across all models.

In this FCP Euro Tech Tip, Danny Kruger, our resident Mercedes-Benz Expert shows you how to inspect each of these sensors for signs of oil wicking into the engine wiring harness. By using Genuine Mercedes parts from the M272 and M273 engines, you can stop the issue in its tracks and save tens of thousands of dollars in damages. Simply add "sacrificial pigtails" at the camshaft adjuster magnets, and begin to replace the camshaft position sensors on a regular interval.
