I didn't think that was true any more, maybe I'm wrong. Thought all OEMs (for cars sold in the US) simply decided to build all vehicles to comply with the strictest emissions standards, IE, California. Do you know of any current Japanese oem examples or even current Mitsu examples who's engines are modified for California emissions compliance compared to the rest of the USA?
Even if true I would be surprised if it made a car that is otherwise e20 compatible in many global markets into one that can technically only handle e10. Open to your feedback.
Side note - CA cars can run at least one tank of approximately e30 without exploding, at least my old girl can. Not sure about 2 tanks though.

That's what i'm wondering too.
I wonder if this issue is more common to a specific regional fuel type blend in Europe vs. North America / Asia?
Have any people outside of Europe experienced this issue?
Almost all of the Gasoline here in Canada is E-10, so one would assume we should be having similar issues here if Ethanol is to blame.

Congratulations on your repair.
I do suspect that both instances of intake valve deposits were probably caused by bad fuel. Your theory about the fuel tanker being polluted by a previous load is one possibility. Another is that fuel is being intentionally polluted by dilution with some other chemical, probably an agricultural use fuel on which there is less tax. I have read of this happening in Ireland where gasoline/petrol fuel is diluted with agricultural use diesel fuel. I don't know how fuel quality testing is done at the fuel pump in Germany.
I am somewhat perturbed by your loss of compression pressure though, as I believe this may be caused by a change in camshaft timing. To remove the intake valves and clean them, your garage would have had to remove the cylinder head and camshafts, so there is the possibility of it being assembled wrongly, and this could cause a change in compression pressure, and then also a change in fuel consumption.
My service manual only covers my 1.2 engine, so I don't know if the 1.0 has variable valve timing like the 1.2, but I would expect it does.
As you obviously have the skills to clean your intake valves, you should be able to measure your camshaft timing and verify it is set correctly. Another more remote possibility is a problem with the variable valve timing, but I would have expected the cam and crank position sensors to have detected this.
