Cam Magnet premature failures
Regarding 2008 ML350. 110,000 miles . Two years ago, I had a P0025 code and replaced the cam magnet part 272-051-01-77 on drivers side exhaust. The P0025 code came back in September and then disappeared. Now it's back again. I change the oil regularly. The car has been driven 19,000 miles since 2016 when the magnet was replaced.
Over the years, I have replaced all the magnets in the car. But I'm concerned that the P0025 cam has failed too soon. What should I expect regarding the life span of these parts. It seems like the failure is premature. Do you experience frequent failures of the Cam Magnets on these M272 engines? thanks for your help

Haven't pulled the plug connection , as yet. Waiting for new part to arrive. The wiring harness is original equipment. Is MB still replacing these harnesses on the recall? Or is that recall closed?

It's interesting that the P0025 fault code has disappeared.The ambient air temperature is warmer. That's the only change. These solenoids have an oil hole to keep the piston lubricate in its sleeve . I'm using 5W30 castrol syntec oil and its only 4000miles old. It's difficult for me to believe that these solenoids could be that sensitive, or said another way, that finicky.
