Good point - no light, so unlikley to be a faulty component. I'll see what
happens this morning.

air filter done yesterday afternoon, diesel filter to be looked at shortly.
But it's not obviously short of power in general.

yeah. The intercooled ones have a "charge temperature sensor" instead of an
"inlet air temperature sensor" (or so sayeth the HBOL), the latter is on the
airbox on this one. Dunno if it plugs into the same wire. The intercooled
ones have the sensor after the cooler, which makes sense.
