What year / month?
Yes, a B47 would work with some creativity.

Some later N47 used the same ecu as the B47, so compatibility is very close.
Amazinjoey I used genuine WinOLS and lots and lots of testing and logging. |

I don't really see the point of replacing for B47 since the timing chain configuration is basically the same. If your engine is not in disasterous condition, you could fix it and save a good amount of money. Ofc you need to tear it down and check.
On what mileage/km did it snap? |

How often did you change your oil, and with what type?

Every 10,000kms, it was Castrol Edge fully synthetic 5w40 and Shell Helix Ultra 5W-40 Pure Plus Fully Synthetic now.

Sounds like a random failure, they do happen. Definitely a bummer.
Although I do wonder if oil choice may have contributed in some way, over time. I thought most LL-04 diesel oils are Xw30 rated, not Xw40. Perhaps the thicker viscosity may have created extra drag? All conjecture, I realize.

I would think there's a stronger correlation between timing chain issues and automatic/manual transmission and using auto start/stop systems

Anyways, as someone said before, it may not be a lost cause after all. It's worth checking the condition of the engine, may still be worth fixing Replacing the N47 with a B47 sounds like more headache than it's worth tbh It definitely is a bummer tho |

Of course the easiest is to replace it with the same engine, but then he wouldn't be asking.
