Or it came from some part that lies between the intercooler and the cylinder ...

Like a sensor.

Probably dropped a valve, most likely scenario really.

Would turbine fragments, if the cold side of turbo blew, make it through a intercooler?

Sounds like the type of language a marketing department would use to avoid having to say that an unfortunate engineer dropped a washer in a place it didn’t belong.

Embarrassing but nothing beyond that.

My first thoughts were valve (or part of) or plug electrode

No one should expect Mercedes to admit to anything interesting....no PU manufacturer ever does.

"Ingested":- To me it means something that gets into a cylinder from outside of it, and as an air filter on the engine intake is used, whatever found it's way into a cylinder is not from the outside of the engine, but from the engine itself. This is unlike the other Mercedes engine that ''swallowed'' or dropped a valve inside the cylinder, which it itself is partly already inside a cylinder.

I just find the idea of foreign debris making its way past the air filters, compressor and intercooler without exploding the compressor into a million pieces a little difficult to believe, personally.

[AR3-GP]

The fact that it's being called "debris" cracks me up.

Next to impossible without complete carnage.

Possibilities are.... valve dropped, spark plug failed dropping ceramic down, no spark causing det/supersonic knock? (might be a little extreme for fully blown failure but could melt a piston), injector failure.

I'd include valve seat in that list. A nice regulation for technical fans would be to require an engine manufacturer to actually explain what happened.......

Why? The information is proprietary. These are trade secrets.

[PlatinumZealot]

Anything that is weak or can be loosened in the intake system I guess. The good news is, that it is unlikely to happen again.

The design and technology is certainly proprietary, but the reason(s) for the failures probably aren't as evidenced by the previous list; the proprietary information is the solution to the problem. My point is that it would be interesting for technical fans if the teams had to describe the failure. The FIA allows modifications to power train components to fix reliability issues, so why shouldn't the teams be required to explain what these issues are to all of us? For an engine manufacturer to get approval to modify an engine for reliability they have to submit their proposed 'fix' to all other engine manufacturers for comment and approval so 'proprietary' is weak sauce.

At least to me it seems close to what happened to FERRARI last year, meaning, and this was never official from FERRARI, which was said to be ''A spark-plug melt down". A spark-plugs nowadays includes the passive pre-chamber build into it.
