The oil geek video explores filter bypass activity vs. low oil temp vs. higher flow.
typical geared pumping oil through filter media
-- Pump has a pressure relief valve near 60Psi
-- Filter has a bypass valve near 10Psi
Side notes...
PAO oil viscosity is less affected by hot/cold temps ie. pressure is more consistent.
PAO 5W-40 flows better than equal synhetic stock when cold.
Our filtration media is not purposely undersized to trigger raw unfiltered oil bypass.
Special aftermarket filter-caps are available WITHOUT any BYPASS to prevent introducing contaminants into bearings on high-RPM high-flow applications.
Bypass primary use is to protect from dirty high sludge engines: not a concern with 5kMi service!

Yeah I have 1 of the first time I heard it. This video sounds slightly different to the recent 1s tho, the more recent 1s sound alot more rattle sound.
yes looks too pronounced, I suggest you to not drive it until you leave it in a garage for diagnostic

Mercedes diagnostic so far is timing chains and tensioners. 28k. I bought the car for 39k. I mean what kind of funny business is this. Currently im in the process of trying to get Mercedes to help with the costs. Seems pretty ridiculous

Would you mind sharing the estimated parts list and labor? Feel free to blackout any private information. I would love to read the vocabulary used in the diagnostic.

Thank you.
I haven't gotten the diagnostic back yet. When I do I'll share it. I'm still waiting for Mercedes Benz to reply to the service department about potentially covering some of the costs. Then when I go pick it up I'll get the diagnostic, because I definitely am not spending 28k on a 39k car.

Wait! Are you saying they want $28,000 to do timing chains and tensioners? That’s nuts! You have an M276 engine? I’d shop around a bit.

I have shopped around at 1 other place so far. They quoted 23k. The list of parts required is mind blowing. If you wish to see my cheaper quote, I can show you.

Would you guys consider aftermarket parts for this job? That would make it significantly cheaper.
What do you understand by aftermarket? I follow this:
1 - Genuine MB
2 - OE means manufacturer of the Genuine but w/o the star
3 - OEM means manufacturer of parts and provider ofbat least another car manufacturer but not MB for that part.
4- aftermarket means anyone making parts, but no manufacturer orders from them

They are emptying and removing the drive axles. Your car must be 4matic, correct?
The camshafts are way overpriced even for MB standards. Here is one genuine part from an MB online dealer ( https://mbparts.mbusa.com/oem-parts/...HjivlkEea8r9nJ)
They are even changing the pressure control valve for each VVT.
Since I am not the one performing the diagnosis, it is unclear why a full timing chain job is required.
I would not let the dealer do this work unless they offer a heavy (50%) discount. They are following the WIS book before opening the engine. For this, you need a mechanic (not a parts changer) who can assess exactly which parts must be replaced and measure things.
On top of that, there is "oops" these parts must also be replaced, say a camshaft or else, Account for extras.

Yeah my thoughts exactly. Imo, it's all assumptions. Nothing anyone has said to me is actual real information. There's 1 stored code, p001177 so I know the intake cam is either faulty or been replaced one before. Other than that they are guessing.
That part you showed me is still $1750 AUD. But still a good bit cheaper than what they quoted. Is that site a good 1? I have been looking at fcp euro, but can't find the genuine cam adjusters there.

Ok. We are talking AUD, not USD. So, AUD $23K ~ USD $16.4K. I would say in the US, an MB dealer will be close by. I have seen $12K quote for the top timing job, no engine out, no front/bottom timing job.
Your estimate includes removing the oil pump.
P0011xx can be a dirty control valve, or it can be a slipped tone wheel. So, keep that in mind.

I thought that code was the camshaft adjuster failure. Not necessarily a slipped tone, but I guess it could be related.

That is LOUD.....
How my KM is your car ?
Your engine is 99% similar to mine. M276.8xx
