it a myth.
Some say that N54 all comes with forged crank and rods. Some say only early years comes with forged crank and rods. VAC opened a N54 and found out crank is forged, rods are kinda forged. Only way to find out is to open your engine. |

N54 crankshaft and CONNECTING RODS are forged. End of story. Virtually no pistons are forged anymore, emissions are HORRIBLE with forged pistons because of all the blow by until warmup.
Crank is clearly forged and rods you can tell because the rod caps are cracked and matched. Build date doesn't matter, the 335is / 1M have the same engine internals. EDIT: somehow typed pistons were forged on accident before.

Correct. I have an 06 build 2007 335i. BPC is currently finishing the rebuild of my engine. Crank is forged, pistons and rods are not.

"Fracture-split connecting rods, however, are manufactured quite differently. The connecting rod is forged as a single piece of metal. Next, using specialized equipment, the large end of the rod is precisely scored. Finally, the cap is then literally ?snapped? from the rod. This process results in an uneven fracture surface on the rod and cap parts. This uneven surface allows for a more precise, durable cap-to-rod fit than is possible with traditionally manufactured connecting rods." I'm not aware of this changing and the ability of different years to sustain loading wouldn't suggest this has changed
