It does make sense.

What doesn't make sense: the car ran completely normally on the weekend trip (400 km round trip), despite the EGR code coming up once on the way there and once on the way back. Not a hiccup from the engine: highway & city driving.

Yet when I was having all the cold start problems (now apparently cured), there were no codes at all.

Regardless, I'll be cleaning that EGR valve & passages.
