This is weird. My wife's 2007 Sedici multijet (21k on the clock) is only really used around town, so knowing the perils of this is I've just taken it on a 100 mile trip at roughly 80mph to try and force a regen . Just got home and the emissions light has come on? Seems like I did it more harm than good. She's only had it since December, so I don't know the type of driving that's been done before she got it, but with such low mileage I'd guess around town and short trips.
Ideas anyone?
