Anyone seen this video? Would love to hear your thoughts...

It recommends:

1. Change oil every 5K
2. Change PCV valve at 60K
3. Replace cooling system at 80K
4. Follow severe schedule maintenance for most drivers
5. Replace transmission fluid at 60K, diff fluid at 50K, power steering fluid at 40K
6. Replace fuel pump at 100K

 

That sounds correct if distances are measured in Miles. Delaying maintenance only increases repair cost.

Besides DO COMBINE (PCV + HPFP) at 100k.Mi. no sense in duplicating labor charges.
Group services at once.

Note 50kMi. ignition tune-up was left ignored....

 

And no mention of brake fluid specifically. Many people forget this until they have problems

 

Yes. Distances are in miles. You make a good point about combining labor charges. At some point, I will talk with my Indy mechanic and devise a strategy for getting this work done.

 

Your engine is M276.9 3.5 liter NA. Yes ?
It shares much components to mine, except I got two turbochargers.

If you really love your car and plans to keep to 20 years and have a good budget and best if you can DIY some to save $$, you can follow my preventive maintenance regime.
I can share with you, but your jaw may dropped a bit

 

I just change the oil 1 year regardless of mileage . I think using recommended oil by the manufacturers is much more important than replacing it "waywardly"

 

... using stock oil ensure stock experience.

 

Sure. I would love to see it.

 

I replace the oil using MB recommended. I have been doing that at 10K miles, but may switch to 5K.

 

Get EPC/WIS and find the equivalent parts on your engine :

I have done almost all of I mentioned in above post and ended up doing much more, due to some dumb-azz error of MB Indonesia for cooling water quality.

--------------------------

I have not done the engine oil pan/snorkle, below green o-ring is dangerous if it leaks, let alone fail.




I have not done the 2 killer o-rings, item 90




Suspension is another different work.
HVAC is another different work
Brake caliper and rotor disc is another different work

I think enough scare already. You can do search on my post,what I been doing for preventive maintenance. It will take you days to read them


Study you car and decides how long you want to keep it, and what category of owner are you :
01. Super sensitive to mechanical aging ? Wants parts to be at its prime at all time ? Car feel like new at all time if possible.
02. Expect zero breakdown ? Thus high level of preventive maintenance.
03. Car is a mechanical pride and not merely a transport machine ? Thus higher budget $$ is ok.

I plan to keep my car to 20th year and from there I shall decide if I want to keep longer, most likely I will.
Thus 10-11th year is a good middle period to refresh parts, knowing 2014 to 2024 those parts held well, thus 2024 new parts would also hold up well to 2034.

To me my car is a pride and joy and mechanical toy I use for physical exercise thru DIY works.
It is not a transport machine per se, I have other cars as transport machine. So I have sentimental value for it on this E400.

So, if your car is just a car with no sentimental value, you do not need to go to the extend of how I maintain my car, it is not worth it as someday the electronics will go kapoot and
MB WILL FOR SURE discontinue selling them and we are probably stranded or have to hunt down also aging USED parts in Ebay...yep, that is a sad fact.

Drive safe......

 

I must be missing something here. The PCV is in the engine compartment and the HPFP is under the back seat, correct? So how does doing both of these duplicate labor charges?

 

Yes, slightly different...:

1. PCV is at rear of Bk1 Exhaust camshaft
2. HPFP is at rear of Bk1 Intake camshaft

these two are really neighbors, not backseat.

Actually HPFP must be removed to service PCV and the interval is the same...

So replace both together at 100kMi.


There are other pairing opportunities:
plugs + boots + CPS + pigtails + Air filter
you get the idea: do it all at once.

....

 

That's a good tip - thanks!

 

No fuel pump under the back seat or in the fuel tank?

 

We were talking about grouping service work to cut down duplicate steps...

[Tank pump + fuel filter] can be grouped: ok

but [Tank pump + PCV] have no relation

HPFP(s) must to be removed to service leaky PCV...


Duplicating repairs book-style is A-Okay standard...

 

What does HPFP mean - in English, please ?

 

Here is Google in Continental English:

 

you have two, a LPFP in the tank and a HPFP under the hood

 

Thanks for that. I think I'll have the indy do the HPFP and the PCV.

Also, I have been trying to find the correct part number for the fuel filter. My VIN # is WDDHF5KB9GB203261, 2016 E350 Base Gasoline. I have looked at at least 10 different MB parts websites and have yet to find any consistency in the 'proper' part number for the filter. I would think that using the VIN# to retrieve the part number would yield the correct part number, but amazingly, it doesn't. Some of the websites say this is an invalid VIN#. Looking at FCPEURO, AutohausAZ, and various MB websites, no consistent answer. I guess I'll just have to uncover the pump in my car to see the correct part number.

For the fuel pump module, there is a mostly consistent part number, 2184700994. I'll check that one to confirm.

 

To be clear, the video is talking about replacing the in tank fuel pump at 100K miles. Do you agree?

 

At about 14:50 of the video, they are talkng about the low pressure fuel pump, under the rear seat, not the HPFP in the engine compartment..

The HPFP was brought into the conversation because you need to remove that to change the PCV valve on some cars, mine in particular. If you are going to remove the HPFP , you might as well replace it. The LPFP for my car runs from $231 to $355 or more. There is also a fuel filter under the other seat. I'm having difficulty determining the correct part number for mine. I am going to pull up the seat bottom and confirm both part numbers, pump and filter.

To bring one more thing into the discussion, the cooling system comments seem out of place if a person has proactively flushed out their cooling system and and replaced the antifreeze at say 50K mileage milestones. I don't think I'll replace mine until I see some sign of a problem ..

 

Well that is a big IF. My maintenance schedule says to replace coolant at 150K not 50K. Also, the video talks about rubber and plastic parts deteriorating due to age and environment, along with thermostat.

 

The video is made by a dude who never actually done any of the job himself

COOLING SYSTEM, aside from thermostat and other fittings for cooling system which is at mechanical coolant circulation pump.

Watch out for these parts :

01. Small pipe between bank 1 and bank 2 coolant return to thermostat. Item 90.


Item 90 broken due to heat :

------------

At the rear of the engine Bank 2, 2 plastic pipe and 2 hose set.
MB hose is very good, but not the plastic end fittings.

I done much more than just those 4 components........

All above is only a small part of the total 10th year refresh...........

 

you might go to an online mercedes dealer, type in your VIN for the proper filter part # then order from FCP or Autohaus AZ

 

I just changed mine in both cars, Just pulled the radiator plug, drained it and refilled
