Boy O Boy do we have the evidence of a mistake on our hands!
This M276 DE 30 LA is a 3.0L Bi-Turbo V6 from a 2017 Mercedes C43 AMG. This engine comes compliments of Matt out of Lubbock TX, Totally appreciate it Matt! This is an engine I would otherwise never get!
The M276 is a V6 family of engines that comes in a TON of 2014 and newer Mercedes vehicles, including but not limited to the C43, E43, GLE450, E400, C400, ML400, S350 and many more. The DE 30 LA is just one variant of this engine.
This poor engine died with just 30k miles on it, a premature failure completely unrelated to design, something that ruins nearly any engine.
its a real shame too, because these are extremely expensive and I'm sure this lesson was an expensive one the driver won't soon forget.
Why am I doing this? I own and run a full service auto salvage business in the Saint Louis Missouri area called Importapart. Part of our model includes dismantling blown engines and salvaging the good parts to resell. We do not rebuild engines, merely supply parts to those who do!
To buy parts you can visit www.Importapart.com or email us at [email protected].

I really hope you enjoyed this teardown. As always, I love all of the comments, feedback and even the criticism.

Catch you on the next one!
