Currently, I drive CLS 400 which shares same engine with C400/450/43AMG. I have done ECU reflashed with charge pressure about 1 bar (14.5 psi)
Can someone who has experience on tuning this engine let me know whether is it still safe if the workshop set more pressure let say about 1.25 bar (18psi)?
I mean safe for engine and related parts like gearbox etc.
Does the inside parts like crankshaft etc also shares same part among 400, 450, 43 AMG?
Thanks

Currently, i'm running at around 20 PSI of boost, I cannot really confirm whether the internals for my m276 is the same exact as yours. AMG does market that there are parts within the engine for the 43 models that from AMG themselves (Nanoslide tech), but I can't really confirm this myself.

See 2 zip files. E43 and E400 engine part numbers.
Compare their part numbers and see what you can find.
Hope this helps
The logic of any power upgrade is this = No extra power is free lunch when it comes to engine longevity, if driven apple to apple hard between stock vs power-upgraded via extra turbo boost only.
The fun part is this, as long as you can afford the repair bills, go for it because a fast car is partly for enjoyment ...so don't worry about $$, if $$ excess is what you have

I’ve owned the C43 with M276 engine for about a year plus and modded it to run 20psi, it was quite difficult getting it to manage and handle that level of boost, and it was especially hard trying to get it to run more. Now comparing it to my current Audi RS4 that runs more than 30psi of boost in stock form, it doesn’t even struggle as much as the Merc with heat management of the intake charge. One major flaw of the M276 is the turbo placement on the sides of the engine rather than the newer style hot-V placement of more current engines on the market.

The core of my set up is the jb4 stack with a tune, and now with wmi for better cooling it's easy at least for me. But wow 30 psi of boost in stock form how much hp are you pushing?

In stock form the RS4 engine makes 450bhp and 600Nm from 2.9L. I might not even tune this one. While I felt the need to constantly improve the power of the C43, the RS4 is plenty fast and just does what I need it to, it doesn’t make me feel like I need any more.

i have compared them with my car vin number parts catalogue. If i compare to C43 AMG the difference only in transmission, the rest like turbocharge, piston, cam and crank shaft, rod all shares same part no. If it compares to E43
AMG the turbocharge and transmission are different part number.

V6 running 30 PSI of boost with only 450 BHP? Or are you saying you have potential to push 30 psi of boost? To each their own of course, 43s just evidently weren't your cup of tea

then maybe it wouldn't push as much boost, assuming the ones from AMG can push more. Tune at your own risk is what I'd say

Yes, you are right, I meant the potential to push 30psi of boost, but in stock form it is 450bhp from 2.9L. It would be interesting to know what the stock boost levels are for the A45S 2.0L running 421bhp.

That's another thing, the A45s is already going to be pushing a high amount of PSI to get 421, pushing around 210 hp per liter** already. At least from my experience, if an A45s can push more than I am with stock internals, the V6 will edge it out on tuning potential, though that may not mean anything if the aftermarket for 45s overcomes the 43, which if the 43 is gone then probably

Reason: didnt mean per cylinder, meant per liter

I don’t think M276 will ever make anything close to that output per cylinder. It doesn’t even have a hot-V turbo arrangement and not to mention strong enough internals. It’s a bit antiquated by today’s standards, to be honest.

I guess you and I just had opposite experiences. Jeffery's 43 is almost pushing 600 on stock internals and that'd be 200 HP per liter. I'm not trying to assert any mechanical superiority of the M276 over other engine, but at least from my experience, with the amount of mods I put on and the 1/4 mile and trap speeds it recorded (not to mention the feel, you say you feel you can get more power, I feel like it's perfect, but that's always subjective) I'd be lying to say that the 43 isn't a sleeper.
Has anyone had knocking under load on these engines.. I was coming up a hill from a slow speed and then put my foot down. The engine was knocking / pinging for a couple of seconds.. I couldnt re-create the fault after this. Not sure if i have a bad tank of fuel..

Were you in full auto, or were you shifting yourself? Fuel might have been it, just asking, because audible knock is hard to create without real fuel/tuning issues. Give more details about your car and the conditions.

Neither does the GT-R. Please tell us your stories about how it takes a hot-v to make power. Be warned, I know about turbo cars, from technology that's almost 40 years old, and also V6. Let me mention, there's not a single C63 that's running as fast as that 40 year old technology. You may proceed.

I was in full auto at the time ( Comfort mode ). I have a 2017 GLC43.. Its been very warm here in Western Australia today, 39degC.. Im wondering if the heat, coupled with aircon on, and driving spirited up the hill caught the engine off guard so to speak..
Its cooled down tonight, and ive been out trying to re-create the knocking, but no luck.. Im just worried the knocking / pinging will damage the engine, so it would have been good to get to the bottom of it..
This is for my '16 C207 E400 Coupe: Anyone DIY their oil changes? Can you draw the oil out from the top through the dipstick tube? What is the correct oil filter? Thanks in advance...
Here's a video I made on how to change your oil at home on a 2016 C450, the process is the same for your car. Just go to the dealership and give them your VIN and they will give you the right filter for like $30-40 CAD.

I use the suction extraction method on my 2014 C350 (M276.957) and used it on my 2004 SL500 (M113.963). I have not done it on my 2015 SL400 (M276.825) yet but will follow that approach. Draining the oil from below is so much more work and inherently more dangerous anytime you get under a car. If the oil filter is on top of the engine, and you have the correct equipment to do so, there is usually no need to get under the car. Using the suction method with a Mityvac 7300 fluid extractor, I can do a complete oil change in about 15 minutes. I have a pancake air compressor and the pneumatic version of the Mityvac extractor, all for a one-time purchase of under $300. Then I get my Mobil 1 0W40 oil from Walmart and my oil filters from FCPEuro.com. I have more than paid for the equipment after a couple of oil changes, which I do every 5000 miles.
Long time ago when rumoured that there is a 3.5L version with Turbo, I thought it was a misprint. It does exist, in very low quantity. The engine variant is called M276.850
If W212 E400 uses M276.820 at 333HP and W213 E43 AMG uses M276.823 I think this is the 396HP ( so I read ) and C43 W205 uses this M276.823 too starting at 367 HP and must be 396HP in later years.
The chassis code, among others is W212.261 E400 or W212.061 E400. Engine is M276DE35LA where the 3.0 is DE30LA.
Damn so many W212 variants ...insane. W205 too.... plenty !!!
Unfortunately I never come across the VIN. Usually if used engine, they sometime list out from which car it comes from and they will sometime show the VIN.
This link sells the engine of 3.5L turbo ( looks so new ) , it shows some data on the car models for the 3.5L engine.
Its a mystery for a long time for me too on this 3.5L Turbo. It was first mentioned in some European forum, Wiki has no info yet on it back then.
Yes, 3.5L lower boost and HP is the same as 3.0TT.
What I am curious to know is, is the 3.5L turbo a 3.5L bolted with turbo or 3.0TT upsize to be 3.5TT ?
Why waste money only to introduce a very low quantity engine and that will make the owners suffer in buying parts.
When I first tried to source M276 3.0TT component in USA, all the website does not show a 2014 E400 as a 3.0TT ( does not exist ), it shows only 2015 being an E400 with 3.0TT.
My engine M276.820 is already a Pariah and confusing when trying to access WIS or EPC due to data collision with M276 3.5L , I can't imagine what a M276.850 3.5TT nightmare will be like for the owner and the workshop.
