That's what I expected too. Until last year, I'd always used my wife's old Accord for city driving and kept the Mondeo for longer, work trips.
But why did it take until the 6th, similar motorway journey for the
ECU to decide on a regen? They were all at similar speeds and the last trip was probably the shortest, which makes me think that there was a soot buildup from the constant speed, low load running.
Maybe city driving with bursts of acceleration does a better job of keeping the DPF clean? I tend to accelerate briskly in the Mondeo, partly because it's how I drive, but also because I was concerned about soot buildup in the DPF.
