M264 vs M274 crankshaft
Could somebody confirm if the crankshaft in the M264 and the M274 are the same part #? My car is last 8 VIN "KU315483". 2019 C300 with the 2.0L M264. Alldata tells me they're the same crankshaft in these two engines, and the manual also says they have the same journal dimensions.

I called my parts buddy that works for a dealer parts dept and he ran my crank vs a 2017 M274 crank, same part number.

264 and 274 are generally the same engine. Same with 254. 264 and 254 are descended from 274 and share many critical parts.

Far as I can tell the only difference is camtronic for the 264.
