The M276 DELA 30 DI BI Turbo V6 Thread
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.
3.5 NA and TT have both larger bore and stroke, so bottom half will be different. This means block, rods, crankshaft.
Cylinder heads, fuel injection. induction and exhaust may or may not be common between the two turbo variants. Not sure if the combustion chamber for a 3.0TT would match up with a 3.5L cylinder bore.
Make a list of parts, then look them up for a 3.5TT and then again for a 3.0TT.
Turbo and intake manifold would be a starting point for me.

The Best of Mercedes & AMG
I own a MB c43 amg w205 287kw 2019.
I have a problem with the fact that on every cold start the car takes a long time to start (spinning) after warming up already catches right away. Has anyone had the same problem? Thanks
This will not throw a code since it starts before computer will trip code.
If it leaks down you need to find out why as many place for the fuel to go when sitting overnight under pressure.
Before replacing parts find out what is wrong.
Strange though as normally MB gives new model # for different engines in the same Chassis W212 so you wold think in 2015 they would the E400 something different due to different engine.
Guess I am thinking back to 70's thru 80's when model number was related to engine size like a 450SEL had 4.5L etc.
SO now model numbers mean nothing....

When was the facelift W212?
In 2015, the E400 was equipped with the 3.0L M276.8 DE LA 30 engine and 4matic powertrain. The 2015 E400 was sold as a Sedan, Coupe, and Wagon.
A Dec/14 production date is a MY 2015 car, so it would have the twin turbo.
