BMW original remanufactured engine
Currently, I am under the situation where I need to replace S65B40 on my E92 M3.
It is being replaced by local BMW dealer, and I saw there are two different engines on the parts catalogue.
One is short engine(new engine) and one is remanufactured engine.
What is the actual difference?
Is there someone who knows BMW remanufacturing process of E92 m3 engine and give me detailed information about difference between two engines, especially equiped parts, quality, material, durability and performance.
