Rattle on startup 2013 E350 4matic 178 k miles




VVT Phasor

Oil control solenoid

This is camshaft adjuster magnet, I forgot the actual EPC name, is the one "pushing" the oil control solenoid to flow oil so that the VVT phasor can change timing by oil pressure management






They go bad like clock work and send engine oil into the harness by capillarity.
This triple timing chain design is amazing

I also considering below
Mercedes Camshaft Position Sensor - Genuine Mercedes 2769051000 | FCP Euro it only around $50 OEM.




I use latest P/N ( revision probably )
My camshaft position sensors not replaced as it is still the current P/N.

But now I think maybe I should get OEM but the price jump quite step:

The MB genuine VVT is make of soft steel that's easily scratched. This was shown in a video where the Canadian guy filled in the wear carved by the pin with weld. He then showed how the weld steel is many folds harder than stock.
I'd select the genuine China quality without the pretty OEM box markups. By the time you need to go back in the engine to work on the next set of VVT, you can inspect existings and pick a remanufactured kit of newer generation parts.
When you receive your parts do a basic Quality-Control, perhaps move the old VVT spring over to replacement unit to closely match the force necessary to actuate.

I've read about every thread I can find concerning the issue, and every comment on every video, and I have yet to read anyone say what you just said.
Could you please share for all those with this horrible issue exactly what oil brand and weight you're using that stopped the startup rattle? I'm not sure what Moly oil is either, please advise.
And you're sure it was the common startup rattle from the camshaft adjuster like you bought? Guess you can't be sure if you didn't tear it apart, and I wouldn't either if the oil solve the problem. Did Yu ever take off the cover rotate the engine and see it skip to identify which one you need? I haven't with mine but I think I can hear its driver side and everyone says the intake goes first I believe.
You know that one will fit though? I'm curious about how Mercedes updates their parts and changes the numbers and such. Sure would save a lot of money to be able to put in the one you bought.
Thank you

How do you know the Uro is actually made in Germany and not just a German brand or China made and put into a box in Germany?
Maybe I just missed it? We have to be so careful these days!

I've used URO parts before, just not for such crucial items as timing system components. I like the fact that FCP Euro carries them, and also Rockauto (although they carry economy, regular and premium brands so you have to pick wisely).
Last place I usually check is Ebay.de when everyone else is expensive. Have found some good deals on name brand parts, even after shipping costs. Had a manual transmission B-Class and some parts were hard to find, especially since it wasn't sold in the U.S. (officially).
