P001885 code advice
My 2012 E350 4Matic has been down for a few months. We’ve just finished replacing the wiring harness, downstream O2 sensors, crank position sensor, cam position sensors, cam magnets, one injector, air/oil separator, brake vacuum pump, and deleted the oil solenoid connection. Whew. It’s running great but I’m now getting the P001885 code.
I plan on switching cam magnets to see if the problem is with the new magnet I installed. On the oft chance the magnet isn’t the problem, could the adjuster be affected by not running the car? I change the oil roughly every 5K so I don’t believe it is sludged up.

This is a good collection of maintenance parts ![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
Add your secondary chain tensioners accessed from the engine front. No need to open camshaft covers or remove injectors.
What's your current mileage?
Did you swap HPFP/Roller?

It has 167k miles on it. I never had a check engine light or any significant issues until I found: oil in the harness, oil leaking at the vacuum pump, and oil in the intake, as well as a split front cv boot — at essentially the same time. Hopefully everything is addressed now. Unfortunately, I didn’t think of the roller. I only put in a new o ring.

Your oil pump solenoid and "Approved 5w40" will help cancel the source of abnormal heat. Some people install pig-tail harness extension to preserve their precious harness from $10k repair job.
- As far as HPFP + Roller: at 160KMi you may need the pair.
- The hard to move pump plunger waste the roller needle bearing that then proceeds to reshape its cam lobes flat.
- The roller is tough but gets wasted when pump acts up.
No rush, listen for noise.
