Yes, but someone on these boards, I think with a G42, had a piggyback, took it off, and the dealer somehow "knew." I'm sure with some searching the thread could be found, but I remember this vividly.
I have theorized it could come down to logs on additive fuel. Why would a car dump way more fuel in normal parameters? That's only my hypothesis though.
