Will the M2 engine require walnut blasting?

The N54 and N55 engines were notorious for needing regular walnut blasting. I think 60k miles was the recommended interval. Any idea if this is still needed on this engine?

They changed the process.

They now use Hazelnuts. Better for the environment.


Oh and I have no idea if it is still recommended! The last BMW I drove was a '97 M3 for 60,000 miles, and never had that process done. My dad's older 5 series and M5's had that done at least once if I recall.

It will eventually at some point need to have the intake valves cleaned. Its a DI motor. I will install a catch can to slow down the carbon build up process.
