Thanks for the reply @CaliBenzDriver !! Yeah I presumed that from reading this thread. Just figured I wanted to double check my pressure was good because of the mileage. I am the second owner, the first had every maintenance record and it has been meticulously taken care of!! No leaks anywhere so far.
@CaliBenzDriver CamPositionSensor?? If that's what that means then yes I did replace all the camshaft sensors because the connectors had signs of oil in them. I checked the cam magnets and they were dry.

Yes, indeed: the standard wet cam sensors.
Did you install the cheap sacrificial extensions with your new CPS ?
They are used to help keep oil out of the engine harness.

I just wanted to log on and say a huge thank you for all the info in this thread!! My 2015 GL450 has 230k miles. I just had the passenger side intake phaser and camshaft replaced along with a few other parts MB recommended while it was apart. The P06DA00 code was current. I want to verify my oil pressure before I disconnect the sensor. Where is the test port so I can check? I have the M276 TT engine.
Here’s a picture of the plug for the oil pressure port. I stripped out mine, but you can locate it right next to the base of the oil filter. When I was measuring my oil pressure once, I dropped the plug (bolt) and couldn’t find it. So I found an inferior bolt that would fit. The plug is the same that is used on the transmission pan to drain out transmission fluid. It is an M12x1.5 plug, part number 000908012009, and I think it uses a 5mm or 6mm hex wrench.
