im parts shopping now, one question- do I need to buy the new bolt that holds adjuster to cam? I’m thinking it’s best to change it, just didn’t know if it comes with the adjuster?
Do not recall any bolt, are you referring to star shaped at the center of the VVT? That is the control valve solenoid
Likely yes. Because it is a minor cost in overall picture of the repair, I would not think about it -> new.
Same as the external bolts for the timing cover, as per WIS
ok what about the tensioners? My car is new enough it has the updated tensions and check valves, however I’ve read some that say they wear and should be changed?
so my “hard parts” would be
cam adjuster
solenoid
2 tensioners.
plus misc. like bolts, sealer.
im also going to change the thermostat while im there
ok so im reading up preparing for this job. my amazon tool kit showed up today.
i think i have the overly simplistic view of what needs to happen, but i have some questions
1- remove intake manfiold (this i have the WIS for this somewhere, there is a goof youtube video also)
2- remove HPFP from rear of pass head (quetion 1)
3- remove pass side cam cover/valve cover- lock down cam with tools
4- R&R cam adjuster (WIS attached to this thread) (Question 2)- have special socket, hold rear with T60
so couple questions
1- is there a WIS for the HPFP removal? ive seen some people say this is hard due to limited space, but cant find much other than that.
2- when aligning timing marks, and i understanding correctly you align the marks on the cam adjusters pointed toward the bolt heads on the tensioners? im not sure how exactly to explain it, but i saw a video that the intake cam should have a mark at like 7 o clock, and the exhaust cam at like 5 oclock. does that sound correct?
also, prior to doing all this, i read about marking the adjusters with white paint, rotating the engine by hand and watching if they jump. is that even necessary since the car is already giving me a code for this particular one?

The attached is for a C-Class, but it's the same engine. Give me your car's model number (212.xxx) and I'll see if there is a different document for your car.

Enter your VIN into www.lastvin.com. You will get your car's datacard that lists all of the configuration items as built. It will also give you your model number. Here's a snippet from my car. My model number is 231.465
You best get a knock-off WIS/EPC from ebay if you want to to any proper work on MB cars/engine.
The small details like torque value of bolts and how sealant path/thickness/width is supposed to be done is important.
The injectors needed to be removed because cylinder head cover is removed, you must buy the seal repair kit and special teflon seat install tool and other special tools too.
I have given you the complete WIS.
All you need to do is read them one by one, the one relevant for your intended work and discover what special tools required and what seal CAN NOT be re-used.
If you do not even want to spend time reading them WIS well, I suggest you don't DIY this job.
I will not spoon feed you, because it is not a good SOP.
I too never done injector removal for M276.x, but have done recently for M271.8 . The concept is the same, but M276 is more complex due to the the drift tool involved due to the mini circlip...I think.
I collected and read the WIS because I too want to learn from MB WIS the proper way and what special tools involved.....because I will do this job someday too.
Doing actual work is Part 2, studying the WIS is Part 1.
There are many example in Utube of which is not a real proper job as per WIS.
Hence start with the WIS and then look at the Utube and see what they missed or what they never did right and don't copy them.

Or make the investment to join the BenzNinja Club and get authentic copies of XENTRY, WIS/ASRA, EPC, Vediamo, and DTS Monaco.
The eBay WIS/EPC knock-offs always require running the software in a virtual machine, which I have found to be problematic when it comes to saving files or printing outside of the VM.

I tried to replace my HPFP on my C350 yesterday and got to the point of almost removing the crash plate covering the pump. I chickened out going further. Partly because it was damned hot in my garage and partly because I knew it might take longer than I was prepared to work on it. Getting the crash plate off was going to be a royal PITA! I may try again in cooler weather. As much as I hate taking the car to the dealer to do work I should be able to, I may also end up doing that.
So, the point Surya makes is a good one. Don't do a DIY job if it's not DIY for you.
NOTE: The engine bay for the C-Class is tight. I have the M276.9xx motor. I cannot imagine how bad it is with a V8 squeezed in there. On the other hand, there are tons of room in my SL400 and I wouldn't think twice about doing the HPFP in that car.

2026 is my plan for PCV system total replacement including 2nd stage oil separator in mid Vee bank.... I am NOT LOOKING forward to it.
Max will be 50,000KM by then, but 12 years old.
i do appreciate the help. i'm just trying to learn as much as i can here before starting the job. its not that its beyond my skill- ive built plenty of engines from 50cc dirtbikes to heavy equipment with pistons as big as my forearm- its just this is my first time tearing into this engine, which is why i was trying to do my pre work education. also, being that i need to order the parts in before i start my work, why i was trying to plan out everything in advance.
i cant view the WIS now im at work, will look at them later. i was also a bit caught off guard because in my searching i didnt see anyone mention needing new seals for the injectors, now ive got parts arriving but apparently i need more parts.
edit- i also misunderstood benzninja a bit. i thought it was just coding, and some diagnostic, i didnt realize it was also all of the WIS info

Yes, you get a full blown copy of XENTRY/DAS (DAS being for older cars), WIS, EPC, etc. that work natively in Windows 10. All the software comes on an SSD. You will need an appropriate laptop (I recommend the Lenovo ThinkPad X260, under $200 refurbed on Amazon) and a C4 multiplexer. But even without the multiplexer, you will have working software. @BenzNinja can point you to good sources for the C4.
Know it doesn’t matter but could be good timing. I have an old laptop I was using for my GM software (EFI live) busted the screen need a new one. Would be great if I can buy 1 laptop that would handle all my garage tuning needs.
now I just need to survive this repair, let my wallet recover some, and order some goodies
