Camshaft adjustment solenoids commonly leak oil from the sealing ring or through the harness connector. If the solenoid is leaking from the electrical connector it should always be replaced and the harnesses included in this kit should be added at the same time to prevent damage to the main engine harness. This will save you money in the long run. It is a common failure on the 4.7L engines and all 2012-2020 Mercedes engines that use these specific magnetic camshaft adjusters where oil destroys your factory engine harness after time. You plug this plug and play wire harness pigtail extensions from the engine harness to the sensors. When they start causing problems from oil spillage you simply unplug them and throw them away and replace with new ones. No special labor require. Unplug from the sensor and plug these in place. Save yourself a lot of headache and money!

We specifically made these to address the issue on the 4.7L M278 engine vehicles, but found out there are other Mercedes engines that use the same sensor.
